Handheld insulator dismounting device

The invention discloses a handheld insulator dismounting device, and relates to the technical field of electric apparatuses. The device comprises a [-shaped plate, a cover plate connected to the top wall of the [-shaped plate, and an L-shaped fixing plate connected to the bottom wall of the [-shaped plate; a clamping telescopic rod and two clamping jaws are connected between the top wall of the C-shaped plate and the cover plate, and the clamping telescopic rod drives the two clamping jaws to clamp the insulator. The L-shaped fixing plate is connected with a guide column and a sliding block movably inserted in the guide column in a penetrating mode. The sliding block is connected with a motor which is connected with a sleeve. The C-shaped plate is connected with a lifting rod, the telescopic end of the lifting rod is connected with the sliding block, the lifting rod is used for driving the motor to ascend and descend, the motor is used for driving the sleeve to rotate, and the nut of the insulator is disassem
