The wire strippers currently on the market are all the size of ordinary hand pliers, which cut and strip the insulation sheath of the cable longitudinally. This kind of wire stripper is convenient, quick, time-saving and labor-saving when stripping the insulation sheath of small-diameter cables below 2cm. But for cables that are directly larger than 2cm, especially some cables that directly reach about 5cm, it is difficult to use this wire stripper to remove the insulation sheath. Therefore, at present, when stripping the insulation sheath of a cable with a larger diameter, generally a staff member is used to cut the insulation sheath of the cable with a blade.

Because the insulation sheath of large-diameter cables is thicker and the material is harder, the staff needs a lot of force to cut the insulation sheath, and the stripping speed is slow; at the same time, because the staff controls the tool by hand, the cutting The depth is difficult to grasp, so it is easy to cut the metal conductor in the cable and affect the use of the cable, and the hands are also easy to be cut.
