During the process, the stripping knife body 501 will repeatedly press the spring 502 for compression. After repeated cutting, the stripping knife body 501 can cut an incision in the insulation layer of the wire harness. The stripping depth of the stripping knife body 501 is adjusted according to the thickness of the insulation layer of the wire harness, so that there is no need to pay attention to the stripping depth when stripping the wire harness, which simplifies the stripping steps before crimping the wire harness. The crimping head is placed between the crimping block 1 301 and the crimping block 2 302, and the stripped wire harness end is placed inside the crimping head.

The surfaces of the crimping block 1 301 and the crimping block 2 302 are integrally formed with a convex strip group. The convex strip thickness of the convex strip group is set to 0.5 mm. The crimping block 1 301 and the crimping block 2 302 are used to crimp the crimping joint. The stripped wire harness end can be crimped with the crimping joint, and the convex strip group improves the stability when clamping the crimping joint.

[0029] Working principle: Use a flat tool to rotate the adjusting bolt 505 to adjust the height position of the bottom plate 504. Since a spring 502 is provided between the bottom plate 504 and the wire stripping knife body 501, the height of the wire stripping knife body 501 protruding from the slot 203 is adjustable. The wire harness is placed on the cutting edge of the wire stripping knife body 501. When the pliers 101 and the pliers 201 are engaged with each other, the cutting edge of the wire stripping knife body 501 will cut the insulation layer of the wire harness. During the process, the wire stripping knife body 501 will repeatedly press the spring. 502 is compressed.
