Abstract

The invention discloses a pair of pliers, which includes: two clamps, each of which is provided with a positioning hole, the two positioning holes cooperate with each other, and the side walls of the clamps are respectively provided with through holes; positioning pins, It is provided with the above two positioning holes; two adjustment blocks are respectively provided in the above two through holes and matched with them; the spring is provided between the side walls of the above two chucks, and the two ends One end of the above-mentioned two adjustment blocks respectively contacting; two handles, which are respectively connected and matched with one end of the above-mentioned chuck. The clamping force of the pliers can avoid damage caused by clamping some soft, hard or brittle objects with the pliers and the phenomenon that some too small objects cannot be firmly clamped.

Description

pliers

【Technical field】

The invention relates to pliers, in particular to pliers with adjustable clamping force.

【Background technique】

Because the functions of the existing pliers are relatively single, the clamping function is limited, and it is impossible to achieve good clamping force control for each object. If you use the existing pliers with springs on the handle: 1. Clamping After some objects with relatively hard or brittle materials, excessive clamping force will easily cause surface deformation and surface damage; clamping phenomenon. All kinds of pliers on the market are of different shapes and sizes. Not every user can find the right pliers for them. The size of the hands of the pliers is different, so that the handle of the pliers becomes long or short. If it is too long, it will be cumbersome to use, and if it is too short, it will be very inconvenient and laborious to use; Volatilization can cause human injury), and it is necessary to keep a safe distance from the special item by hand. If it is too long, it is inconvenient to hold and use, and if it is too short, it will cause harm to the human body.

【Content of invention】

In view of this, the object of the present invention is to provide a kind of pliers, through the clamping force of the pliers, it can avoid the phenomenon of damage caused by the use of pliers to clamp some soft, hard or brittle objects and clamp some objects with too small volume. A phenomenon in which an object cannot be firmly held.

To achieve the above object, the present invention provides a kind of pliers, which comprises:

Two chucks, each with a positioning hole, the two positioning holes cooperate with each other, and the side walls of the chuck are also provided with through holes;

A positioning pin, which is provided with the above two positioning holes;

Two adjustment blocks, which are respectively arranged in the above two through holes, and cooperate with them;

a spring, which is arranged between the side walls of the two chucks, and whose two ends respectively contact one end of the two adjustment blocks;

Two handles are respectively connected and matched with one end of the chuck.

In particular, the internal thread provided in the above-mentioned through hole cooperates with the external thread provided on the adjusting block.

In particular, the above-mentioned handle and the chuck are threadedly fitted.

Compared with the prior art, the clamping force of the pliers of the present invention can avoid damage caused by the use of pliers to clamp some soft, hard or brittle objects, and some objects that are too small in size cannot be firmly clamped Phenomenon.

In order to have a further understanding of the purpose of the present invention, structural features and functions thereof, the detailed description is as follows in conjunction with the accompanying drawings:

【Description of drawings】

FIG. 1 is a schematic diagram of the structure of the pliers of the present invention.

FIG. 2 is an exploded schematic diagram of the structure of the pliers of the present invention.

【Detailed ways】

Referring to Fig. 1 and Fig. 2, the pliers of the present invention includes: .

Two chucks 11, each chuck 11 is provided with a positioning hole 111, the two positioning holes 111 cooperate with each other, the side wall of the chuck 11 is also respectively provided with a through hole 112, in this embodiment, the The through hole 112 is provided with an internal thread;

The positioning pin 12 is provided with the above-mentioned two positioning holes 111, and the positioning pin 12 can be matched with the positioning hole 111 by other methods such as riveting;

Two adjustment blocks 13, which are respectively arranged in the above two through holes 112, and the external threads provided on them cooperate with the internal threads of the through holes 112, so as to adjust the telescopic length;

Spring 14, which is located between the side walls of the above-mentioned two chucks 11, this spring 14 is in contact with one end of the above-mentioned regulating block 13, and controls the size of its elastic force through the expansion and contraction of the regulating block 13;

Two handles 15 are respectively connected and matched with one end of the above-mentioned clamp 11. In a preferred embodiment, the handle 15 and one end of the clamp 11 are threadedly fitted, and the handle 15 and the clamp 11 can be adjusted in this way the combined length.

In this embodiment, the pliers have the following effects: 1. Turn the adjusting blocks 13 on both sides to adjust the elastic force of the spring, thereby adjusting the clamping force of the pliers chuck 11, and then avoid using the pliers to clamp some soft, hard or Objects of relatively brittle materials cause damage, avoiding the phenomenon that some objects that are too small in size cannot be firmly clamped; 2. The length of the handle 15 can be adjusted through the thread on the handle 15 of the pliers. After adjustment, each user can Find the right length to use to hold the right object.
