In the prior art, wire strippers include a clamping portion and a shearing portion. When the stripper is used to strip the skin, the clamping portion clamps the skin, and the cutting portion cuts the skin and removes the stripped portion. The split thread sheath is not peeled off, and a clamp mark of the clamping part is left on the thread sheath. In the action process, the clamping part plays a role in fixing and clamping, and the shearing part shears the thread skin and removes the stripped thread skin. For example, in the wire strippers disclosed in chinese patent nos. ZL200820134236.4, ZL 200820137083.9, and ZL201220255751.4, the clamping portions are all provided on the left side, and the cutting portions are all provided on the right side.
