Background Art

In the prior art, conventional meter installation and connection pliers are simple in design and single in function, and are mainly used for specific tasks, and are not convenient enough in actual meter installation and connection operations. In particular, when stripping the outer sheath of the wire, conventional pliers cannot effectively store and organize the stripped wire ends, which requires extra time and manpower for cleaning after the work is completed.

Although existing technologies such as the Chinese invention patent with authorization announcement number CN109586212B discloses an environmentally friendly wire stripper, it uses two handles, a cross-rotatable axis, a cutting blade, a storage box and other structures to achieve the storage and arrangement of the stripped insulation layer while stripping the wire, achieving an environmentally friendly effect.

However, when using such a wire stripper, the insulation layer of the wire harness needs to be cut by the cutting blade first, and then the cutting blade is pressed against the stripped insulation layer and the stripped insulation layer is pulled off the wire harness. This process may damage the cutting blade, thereby shortening the service life of the wire stripper. Therefore, although the existing wire stripper provides storage and organization functions to a certain extent, there are still some problems and limitations in actual operation, which need further improvement and optimization.

Embodiment 1: As shown in FIGS. 1 to 4, the multifunctional pliers for connecting the meter to the power supply of the present application include a pliers body 100 and a pliers head 200; the pliers body 100 includes two handles 110 and a compression spring 130 cross-hinged by a hinge shaft 120, and the two ends of the compression spring 130 are respectively fixed to one end of the two handles 110. The pliers body 100 is a prior art and will not be described in detail here; the pliers head 200 is arranged at one end of the handle 110 away from the compression spring 130; the pliers head 200 includes a bottom plate 210, a blade 220, and a pressure block 230 and box body 240; there are two bottom plates 210, and the bottom plates 210 correspond to the handles 110 one by one; the bottom plates 210 are rectangular plates as a whole, and the bottom plates 210 are detachably arranged on the corresponding handles 110, and the two bottom plates 210 are opposite to each other; in the initial state, the length direction of the bottom plates 210 is perpendicular to the axial direction of the hinge shaft 120; blades 220 are fixed on one side of the two bottom plates 210 away from the hinge shaft 120, and the two blades 220 are arranged opposite to each other, and the blades 220 are provided with There are multiple wire stripping ports of different sizes, which is the prior art; in the initial state, the length direction of the blade 220 is the same as the axial direction of the hinge shaft 120; the blade 220 is located at the end of the bottom plate 210 away from the hinge shaft 120, and the two blades 220 are arranged opposite to each other; a pressure block 230 is arranged on the side of the blade 220 close to the hinge shaft 120, and the pressure block 230 is fixed on the corresponding bottom plate 210, and the pressure block 230 is arranged parallel to the blade 220; the material of the pressure block 230 is elastic rubber A box body 240 is fixed on each of the two bottom plates 210, and one end of the box body 240 close to the blade 220 is open and the opposite ends of the two box bodies 240 are open; the opening of one end of the box body 240 close to the blade 220 abuts against one end of the pressure block 230 close to the hinge shaft 120; when the pliers head 200 is fully closed, the blades of the two blades 220 abut against each other, and at this time, the two pressure blocks 230 also abut against each other, and the two pressure blocks 230 and the two box bodies 240 are combined into a hollow rectangular parallelepiped.

When the multifunctional pliers of the embodiment of the present application are actually operated, the steps are as follows:

S1: Check the stripping opening on the blade 220 and select a stripping opening size suitable for the current work;

S2: Fix the two bottom plates 210 on the corresponding handles 110 respectively, place the wire to be stripped between the two blades 220, and one end of the wire should extend into the box body 240. By holding the handle 110 tightly, the two blades 220 are brought close to each other, thereby clamping the wire;

S3: Continue to hold the handle 110 tightly, ensure that the wire is stably clamped by the blade 220, and gently pull the other end of the wire outward, so that the insulation layer of the wire is cut off at the blade of the blade 220.

Embodiment 2: The multifunctional pliers in the above embodiment are difficult to operate effectively when encountering some special scenarios (such as narrow and long areas); the embodiment of the present application is optimized to a certain extent on the basis of the above embodiment.

As shown in Figures 5 to 8, the base plate 210 in this embodiment is detachably arranged on the corresponding handle 110 through an adjustment component 250; the adjustment component 250 includes a rotating shaft 251 and a nut 252; the rotating shaft 251 is a circular shaft as a whole, one end of the rotating shaft 251 is fixed to the center of the corresponding base plate 210 away from the box body 240, and the rotating shaft 251 passes through the handle 110, and a threaded line that meshes with the nut 252 is provided on the part of the rotating shaft 251 extending out of the handle 110; the nut 252 is threadedly connected to the rotating shaft 251, and the rotating shaft 251 is rotatably connected to the handle 110; when the nut 252 is rotated in a direction away from the handle 110, the base plate 210 can be controlled to rotate around the rotating shaft 251, and the nut 252 is rotated in a direction away from the handle 110. When tightened in the direction close to the handle 110, the base plate 210 and the handle 110 are tightly fitted together. At this time, the base plate 210 and the handle 110 are relatively still due to the friction between the two; the thickness of the end of the box body 240 away from the blade 220 is 2 to 3 cm, which can be used as a pressurizing end; the position and angle of the base plate 210 on the handle 110 are controlled by the adjustment component 250, so as to achieve flexible control of the direction of the pliers head 200. When the base plate 210 is rotated 180 degrees by the adjustment component 250, the end of the box body 240 away from the blade 220 becomes the operating end, and this end can be used as a pressurizing end. In addition, by adjusting the rotation direction of the base plate 210, the pliers head 200 can adapt to different adaptation scenarios (such as narrow and long areas).

The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

1. By providing the adjustment component 250, the bottom plate 210 can be flexibly adjusted and fixed relative to the handle 110, thereby improving the adaptability and flexibility of the pliers head 200, so that the pliers head 200 can easily adapt to different working scenes and angle requirements;

2. The threaded connection design between the nut 252 and the rotating shaft 251 allows the position of the base plate 210 to be fixed by tightening the nut 252 after adjusting the angle of the base plate 210, ensuring that it will not shake or change angle due to external force during work, and the stability and accuracy of the pliers head 200 can be maintained even in a complex working environment.

3. One end of the box body 240 away from the blade 220 is designed as a pressurizing end. When the bottom plate 210 rotates 180 degrees, this end can be used as an operating end for pressurizing operation, which can more conveniently perform wire stripping or clamping operations.

4. By adjusting the rotation direction and angle of the base plate 210, the clamp head 200 can adapt to more different application scenarios, such as narrow areas, complex angles, etc., greatly expanding the scope of use of the multifunctional pliers for meter installation and power connection.

Embodiment 3: In the above embodiment, the discarded insulating layer of the multifunctional pliers may fall out of the box body 240 during continuous use; the embodiment of the present application is optimized based on the above embodiment.

As shown in Figures 9 and 10, the pliers head 200 also includes a stretching body 260; the stretching body 260 is rectangular as a whole, there are two stretching bodies 260, and the length direction of the stretching body 260 is perpendicular to the length direction of the blade 220; the two stretching bodies 260 are both located inside the hollow rectangular parallelepiped formed by the two box bodies 240, and the two stretching bodies 260 are arranged opposite to each other; the stretching body 260 is attached to the inner wall of the hollow rectangular parallelepiped formed by the two box bodies 240, and the two ends of the stretching body 260 are respectively fixed on the inner walls of the end faces of the two box bodies 240 away from each other, so that the gaps on both sides between the two box bodies 240 along the length direction of the blade 220 can be covered by the two stretching bodies 260; the material of the stretching body 260 is elastic rubber material, and the stretching body 260 is in a stretched state in the initial state. When the pliers head 200 is closed, the stretching body 260 is folded as a whole.

Further, as shown in FIGS. 11 and 12 , the stretching body 260 is composed of an outer layer 261 and a resistance layer 262, wherein the outer layer 261 is located on the side of the stretching body 260 close to the outside of the box body 240, and the resistance layer 262 is close to the inner center point of the box body 240, and the outer layer 261 and the resistance layer 262 are integrally combined into a closed bag structure, and the internal space is an inner cavity; the elastic coefficient of the resistance layer 262 is smaller than the elastic coefficient of the outer layer 261; in this embodiment, the inner cavity of the stretching body 260 is filled with air. In the initial state, the two stretching bodies 260 are flat. When the pliers head 200 is closed, the two stretching bodies 260 shrink and fold. At this time, the gas in the inner cavity is squeezed, so that the resistance layer 262 expands toward the center point of the box body 240, so that the stretching body 260 can limit the waste insulation layer located in the box body 240. When the pliers head 200 is opened, the stretching body 260 is elongated, and the waste insulation layer located in the box body 240 is no longer restricted by the stretching body 260, and can be dumped more conveniently.

The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

1. By providing two stretching bodies 260, the gaps on both sides of the box body 240 along the length direction of the blade 220 can be effectively blocked, thereby significantly enhancing the sealing of the pliers head 200 in the closed state, helping to prevent waste insulation layers or other debris from scattering from the gaps during operation, thereby improving the cleanliness and safety of the operation;

2. The stretching body 260 is made of elastic rubber material and is designed to be in a stretched state in the initial state, so that the stretching body 260 can be folded as a whole when the clamp head 200 is closed, and can be stretched when the clamp head 200 is opened, which is not only convenient for operation, but also can maintain stable performance in different usage scenarios;

3. By providing a design of a stretching body 260 with an inner cavity and gas filling, when the clamp head 200 is closed, the force generated by the gas compression can be used to expand the resistance layer 262 toward the center point inside the box body 240, thereby effectively limiting the waste insulation layer, ensuring that the waste insulation layer will not move or scatter at will during the operation, and further improving the stability and safety of the operation;

4. When the clamp head 200 is opened, the stretching body 260 is stretched, and the waste insulation layer in the box body 240 is no longer restricted by the stretching body 260, so it can be dumped and processed more conveniently, which not only simplifies the waste processing process and facilitates the wire harness to be inserted into the box body 240, but also improves the operating efficiency;

5. The material selection (elastic rubber) and structural design (different elastic coefficients of the inner and outer layers) of the stretching body 260 can ensure that it has good durability and stability during use, thereby extending the service life of the pliers head 200.

Embodiment 4: In the above embodiment, if there are many discarded insulating layers between the two stretching bodies 260, the discarded insulating layers will move around or even scatter, making the multifunctional pliers inconvenient to use; the embodiment of the present application is optimized based on the above embodiment.

As shown in FIG. 13 , the inner cavity is filled with an inner medium 263, and each of the resisting layers 262 is provided with 20 to 50 through holes; the inner medium 263 is made of keyboard cleaning glue, which is soft and elastic, has excellent elasticity and tensile properties, and can be repeatedly stretched and rubbed without breaking easily; in the initial state, the inner medium 263 is entirely located inside the cavity, and when the clamp head 200 is closed, a portion of the inner medium 263 extends out of the through hole under the restriction of the stretching body 260 to contact the discarded insulating layer, and sticks the discarded insulating layer. When there are many discarded insulating layers between the two stretching bodies 260, the stretching bodies 260 are squeezed, so that more of the inner medium 263 extending out of the through hole contacts the discarded insulating layer, and the limiting effect is better. At the same time, due to the elasticity of the inner medium 263, when the pliers head 200 is opened, the inner medium 263 will become flat along with the stretching bodies 260, and will not cause too much obstruction when taking out the discarded insulating layer. In addition, due to the repeated use of the inner medium 263 and only a part of it contacts the discarded insulating layer, its service life is longer.

Preferably, the inner medium 263 is Cyber Clean brand keyboard cleaning glue, and the inner medium 263 may also be rubber or gel with a specific ratio.

The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

1. When the clamp head 200 is closed, the compression of the stretching body 260 causes the inner medium 263 to contact the waste insulation layer through the through hole, forming a tight limiting structure, effectively preventing the waste insulation layer from moving or scattering;

2. Due to the elasticity and compressibility of the inner dielectric 263, it can adaptively adjust the limiting effect according to the amount of waste insulation layer. When there are more waste insulation layers, the inner dielectric 263 will squeeze out more through the through hole and contact the insulation layer, thereby enhancing the limiting effect;

3. When the clamp head 200 is opened, the stretching body 260 and the inner medium 263 will return to their initial state, so that the waste insulation layer can be easily dumped or taken out without causing excessive obstruction.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
