[0002] In the process of overhauling the line, in order to judge whether there is a break in the circuit, thereby determining the fault location and repairing, the corresponding wire needs to be short-circuited, and wire short-circuiting refers to the phenomenon that two or more conductors are in direct contact. During the short-circuiting process, the maintenance personnel need to use wire strippers to strip the insulation layer at both ends of the short-circuiting wire. Therefore, it can be seen that wire strippers are indispensable tools in wire short-circuiting.

[0003] At present, the existing wire strippers mainly consist of a handle and a head.
