Maintenance equipment for power maintenance

A cavity is formed in a fixing device, the inner wall of the cavity is movably connected with a rotating ring in a sleeving mode, rotating grooves are formed in the front wall face and the rear wall face, close to the inner circle of the fixing device, of the rotating ring, and the rotating ring is movably connected with the bottom end of a wire fixing rod through the rotating grooves. And the top end of the wire fixing rod passes through the inner ring of the fixing device and is fixedly connected with the wire fixing clamp. According to the invention, the push piece movably sleeved with the adjusting hole is arranged on one side of the upper end of the fixing device, the rotating ring is movably arranged in the fixing device, and the push piece is fixedly connected with the rotating ring, so that the rotation of the rotating ring can be realized only by pushing the push piece to rotate, and the rotating ring is promoted to drive the four wire fixing rods to synchronously move up and down; the cable fixing c
