High-altitude operation power line repair equipment

The invention discloses high-altitude operation power line repair equipment which comprises a main pedal and an outer buckling ring; a sliding groove is formed in the main pedal, the outer buckling ring is slidably connected into the sliding groove in a sleeved mode, a toothed plate and an inner ratchet are arranged on the two side faces of the outer buckling ring correspondingly, and a U-shaped piston is arranged in the main pedal; the two ends of the U-shaped piston are sleeved with connecting rods in a sliding mode, and the connecting rods are connected with a reverse rotation preventing device and a threaded rod correspondingly. The pressure effect of the human body gravity on the threaded rod is utilized, and the transmission performance of the inner threaded gear on the outer buckling ring is matched, so that the outer buckling ring can rotate, and the purpose of adjusting the inner diameter of the ring, making contact with the telegraph pole, of the outer buckling ring is achieved; and by increasing th
