In the above-mentioned hand-held cable stripping tool, the support is screwed with a limit pin for restricting the downward movement of the handle.

In the above-mentioned hand-held cable stripping tool, the center distance between the front pulley and the rear pulley is 60-70 mm; the length of the blade holder is 120-150 mm.

In the above hand-held cable stripping tool, the front pulley and the rear pulley are both V-shaped pulleys, the two side plates are connected by a threaded connecting rod, and the right end of the connecting rod is screwed with the front end of the support.

The beneficial effects of the present invention are: the pulley is used as the track of the cable, the pulley rolls when the cable is longitudinally cut, and the friction force is reduced. During ring stripping, the cable can be fixed in the V-groove to keep the cable stable and prevent the cable from slipping out during stripping. Control the depth of stripping by adjusting the depth of the bolt drive fine-tuning the tip into the cable. The tool is easy to carry and can be operated by a single person to realize peeling, which is very convenient for construction personnel to work at high altitudes or work alone, save labor and equipment costs, and improve work efficiency.
