Detailed Description

Referring to fig. 1-4, the novel wire stripper of the present invention comprises a first housing 1, a second housing 2 and a collet a10, wherein the first housing 1 comprises a collet B11 and a left handle 12, one end of the second housing 2 is a right handle 22, the other end is a fixed end 20, the fixed end 20 is fixed with a first shear blade 21, and the first shear blade 21 is rotatably connected to a second shear blade 3; the cartridge a10 and the cartridge B11 are provided with left and right knife rests 4, and a torsion spring is provided between the left and right knife rests 4, as shown in fig. 1, and functions such that the cartridge a10 and the cartridge B11 are in an open state without receiving an external force. The left and right tool rests 4 are rotatably connected with a limiting column 6 through a connecting frame 5; the pushing piece 7 is rotatably connected in the second shell 2, one end, far away from the tool rest, of the chuck A10 is provided with a bevel edge 101, the end extends into the first shell 1, the pushing piece 7 abuts against the bevel edge 101, and the pushing piece 7 moves towards the left grab handle 12 to sequentially push the bevel edge 101 and the limiting column 6 during shearing or stripping.

And the end parts of the contact parts of the limiting columns 6 and the pushing pieces 7 are provided with rotating wheels 67. The inner side of the left grab handle 12 is provided with a limiting step 121 and a through hole 122 for the limiting column 6 to penetrate through, the limiting column 6 is sleeved with an elastic part 8, and two ends of the elastic part 8 are respectively abutted against the through hole 122 and the rotating wheel 67.

A torsion spring is arranged between the pushing piece 7 and the second shell 2. As shown in FIG. 2, when the inclined plane 101 cannot be pushed continuously, the torsion spring realizes that the pushing piece 7 pushes the limit post 6 to move downwards continuously.

The second shear blade 3 is fixedly connected with the first shell 1.

Specifically, as shown in fig. 1, the two points a.b are the rotation pivots of stripping and cutting respectively. The shearing function is realized by matching the first shearing blade 21 and the second shearing blade 3, as shown in the attached figures 1-2, when the left grab handle 12 and the right grab handle 22 are held by hands, the end parts of the first shearing blade 21 and the second shearing blade 3 which are respectively fixed on the first shell 1 and the second shell 2 and are rotationally connected with each other at a point B are used for cross shearing.

When the wire is stripped, as shown in the attached figures 1-2, the left and right grab handles are close to each other, the runner 67 of the pushing piece 7 on the shell body 2 connected through the torsion spring in a rotating mode pushes the inclined plane 101, namely one end of the chuck A10 is stressed, the other end of the chuck A is moved towards the chuck B11 around the fixed point C, the chuck A10 and the chuck B11 are achieved to clamp and fix the wire, when the two chucks clamp the wire, the left and right knife rests 4 positioned inside the two chucks are clamped with the wire, namely the blade for stripping the wire is clamped on the outer wall of the wire. The inclined plane 101 is no longer moved, and the distance between the inclined plane 101 and the roller 67 on the spacing column 6 is smaller than the diameter of the roller 67 on the pushing part 7. The rotating wheel 67 of the continuous force applying pushing piece 7 abuts against the rotating wheel 67 on the limiting column 6 and pushes the limiting column 6 to compress the elastic piece 8 downwards, as shown in fig. 4, until the rotating wheel 67 at the end part of the limiting column 6 abuts against the limiting step 121, and the left and right grab handles cannot move continuously. The limiting column 6 compresses the elastic piece 8 downwards and simultaneously pulls the connecting frame 5 connected with the limiting column to move downwards, the connecting frame 5 pulls the left and right knife rests 4 to move downwards along the clamping head B11 and the clamping head A10, and the blades for stripping the wires also move downwards to drive the skins to be stripped on the wires, so that the operation of stripping the cables is realized. The fixed point C is the point a.

The utility model discloses the effectual limited problem of application scope who has improved current wire stripping pliers. Through install the cutter on wire stripping pliers and make it have the function of shearing, structural design is reasonable ingenious, and the function is various, and the practicality is strong.
