Description

Wire stripper

Technical Field

The utility model relates to an electrician tool, in particular to a portable small-sized wire stripper.

Background

At present, wire stripping tools are of various types, but most of common electricians commonly use stripper pliers. The wire stripper is easy to handle wires with small wire diameters and short stripping lengths. However, in some electricians, the operation of large wire warps or large peeling length is often encountered, and the common wire stripper cannot be used. The utility model patent of application number 201921600159.1 discloses a waste wire stripper which can be used for stripping the outer skin and the wire core of a wire, is mainly applied to stripping work of waste wires and has a good use effect. However, the damage to the wire core during peeling is not considered because the wire is aimed at waste wires. The structure adopts a design of matching the guide wheel with the blade, and the cutting depth of the blade is not well regulated. When the blade cuts the wire sheath, the blade can also penetrate into the wire core to scratch the wire core. Therefore, it is not suitable for the peeling work of a normal wire in the wire laying work.

Disclosure of Invention

Aiming at the problems, the utility model provides the portable wire stripper with good use effect.

The technical scheme is that the wire stripper comprises a bracket, guide wheels and blades, wherein V-shaped grooves are formed in the peripheral surface of each guide wheel ring, the bracket is a rectangular frame formed by plates, side plates on two sides of the bracket are provided with sliding grooves which are vertically arranged, the guide wheels are rotatably arranged on the bracket below the sliding grooves through guide wheel shafts, an adjustable knife rest in a door shape is arranged above the guide wheels, the bottoms of the adjustable knife rest are provided with wire pressing wheels, each wire pressing wheel is formed by two wheels which can rotate independently and are separated by a certain gap, the wheel shafts of the wire pressing wheels are parallel to the guide wheel shafts, two ends of each wire pressing wheel extend out of the side edges of the adjustable knife rest and extend into the sliding grooves on the side plates on two sides of the bracket, the blades are arranged at the gaps between the wire pressing wheels, the knife tips face the middle positions of the guide wheels, the top ends of the bracket are in threaded connection with adjusting bolts, and the bottoms of the adjusting bolts are rotatably connected with the tops of the adjustable knife rest.

The utility model has the advantages of simple structure, small volume and convenient pushing and using. The wire diameter and the stripping depth of the wire can be adjusted, and the wire stripping machine is suitable for stripping common wires. The peeling operation of the electric wire can be completed manually or by driving an electric tool such as an electric drill.

Detailed Description

As shown in fig. 1 and 2, an electric wire stripper comprises a bracket 1, a guide wheel 2 and a blade 3, wherein a V-shaped groove is formed on the circumferential surface of the guide wheel 2, the V-shaped groove can play a role of aligning knife tips, the bracket 1 is a rectangular frame formed by plates, side plates on two sides of the bracket 1 are provided with sliding grooves 4 which are vertically arranged, the guide wheel 2 is rotatably arranged below the sliding grooves 4 on the bracket 1 through a guide wheel shaft 5, an adjustable knife rest 6 in a shape of a door surrounded by a top edge and two side edges is arranged above the guide wheel 2, a wire pressing wheel 7 is arranged at the bottom of the adjustable knife rest 6, the wheel shaft 8 of the wire pressing wheel 7 is parallel to the guide wheel shaft 5, two ends of the wheel shaft 8 of the wire pressing wheel 7 extend out from the side edges of the adjustable knife rest 6 and extend into the sliding grooves 4 of the side plates on two sides of the bracket 1, the blade 3 is arranged at the gap in the middle of the wire pressing wheel 7, the knife tips face the middle position of the guide wheel 2, the top end of the bracket 1 is in threaded connection with an adjusting bolt 9, and the bottom of the adjusting bolt 9 is connected with the top of the adjustable knife rest 6 in a rotatable manner. The adjusting bolt can be rotated to enable the adjusting tool rest to slide up and down along the chute. The electric wire stretches into the groove between the guide wheel and the wire pressing wheel, the wire pressing wheel can press the electric wire through the adjusting bolt, and the cutter point stretches into the outer skin of the electric wire. The wire sheath can be axially split by pulling the wire or rotating the guide wheel. The bracket and the adjustable tool rest can limit the left-right clearance of the adjustable tool rest by reserving a smaller clearance, and also can process the two ends of the wheel shaft of the wire pressing wheel into a flat shape, and limit the left-right clearance of the adjustable tool rest by matching the steps with the inner sides of the side plates of the bracket, so that the wheel shaft can only slide up and down and cannot move in the front-back left-right direction.

The upper side of the wire pressing wheel 7 is provided with a blade fixing part 10, a hole is formed in the wheel shaft 8 of the wire pressing wheel 7, and the blade 3 is fixed on the blade fixing part 10 and passes through the hole on the wheel shaft 8 of the wire pressing wheel 7. The blade may use a wallpaper blade.

The blade fixing part 10 is vertically provided with a blade fixing hole, the blade fixing hole can be opened in three directions, the disassembly is convenient, and the blade 3 is fixed on the blade fixing part 10 through a locking screw 11. The extending length of the cutter point can be adjusted by adjusting the position of the cutter blade up and down, so that the depth of the cutter point for cutting the wire sheath can be controlled more accurately. The locking screw can be screwed by extending into the tool through a sliding groove on the bracket.

Recessed arc-shaped ring grooves are formed in the positions, adjacent to the rims, of the two wheels of the wire pressing wheel 7. The arcuate groove may be used to provide greater contact with the wire skin to make the blade easier to sever the wire skin.

One end of the guide wheel shaft 5 extends out of the bracket for a certain distance to serve as a connecting part with a driving device. To facilitate connection of electric drills and the like the electric tool is driven.

The bottom of the bracket 1 is provided with a handle 12.

The surface of the V-shaped groove of the guide wheel 2 is provided with anti-skid patterns. The anti-slip lines are arranged transversely along the surface, and can play a role in preventing the electric wires from sliding when the electric tools are used for driving so as to ensure stable feeding of the electric wires.
