Description

Technical Field

[0001] The invention relates to a cable insulation stripping device, in particular to a cable electric wire opening device. Background Art

[0002] When laying cables or recycling cables, the insulation skin on the outer surface of the cables needs to be stripped off. The traditional method is to manually use a stripping knife to cut the insulation skin, which has low operating efficiency and high labor intensity. With the development of science and technology, some electric strippers have appeared. The blades are automatically rotated on the outside of the cable to achieve stripping. However, the clamping stability of the cable by such electric strippers is poor. When working, the stripper is prone to shaking along the radial direction of the cable relative to the cable, resulting in the blades easily damaging the wires in the cable during the stripping process. Therefore, a stripper with better cable stripping effect is needed. Summary of the invention
