[0002] During the process of power construction, it is often necessary to strip the cable insulation sheath. A common cable insulation stripping device is a cable stripper. When using the cable stripper, the cable is first clamped by two clamp arms, and then the two clamp arms are rotated to make the blades perform circular cutting on the cable insulation sheath, loosen the cable, and then the blades are used to perform axial cutting on the cable to strip the cable insulation sheath. However, during the use of the cable stripper, manual circular cutting requires the operator to firmly grasp the two clamp arms and rotate the two clamp arms at the same time, which is slow and laborious. At the same time, after radial cutting, the direction of the blade needs to be adjusted before radial cutting can be performed, which is troublesome to operate.

[0003] Therefore, a power cable stripping device is needed to solve the above problems. Utility Model Content
