Cable stripping device

The invention relates to the field of power supply system line construction auxiliary facilities, and particularly discloses a cable stripping device. The cutting device comprises a fixing plate, a rotating gear driven by a driving motor is installed on the fixing plate, the fixing plate and the rotating gear are each provided with a U-shaped notch, two limiting clamping blocks capable of sliding are arranged on the rotating gear, the limiting clamping blocks are matched with a distance adjusting device and a fixing device, and a cutting device is installed on the limiting clamping blocks. According to the invention, through cooperation of the limiting clamping block, the fixing device and the adjusting device, the position of the cable is limited, then the driving motor drives the rotating gear to rotate, and meanwhile, the cable cutting device moves along the length direction of the cable under the action of external force; therefore, in the rotating process of the rotating gear, the cutting knife spirally
