Special tool for power-cut or live replacement of 220kV spacer

The invention discloses a special tool for power-cut or live replacement of a 220kV spacer. The tool is characterized by comprising an upper hook and a lower hook, wherein a labor saving screw is respectively connected between the upper hook and the lower hook in a screw-thread fit manner; hook ends of the upper hook and the lower hook are respectively connected to a trigger locking hook; after trigger devices trigger, locking devices lock the trigger locking hooks, so that the upper hook and the corresponding trigger locking hook are closed to form a round structure, and the lower hook and the corresponding trigger locking hook are closed to form a round structure; one side of the upper hook is fixedly connected to a pulley, one side of the lower hook is fixedly connected to an insulating bar connecting piece, and a screw is fixed through screw locking devices. The tool has the following beneficial effects that the problems of tedious steps, long operation time, large working strength, high operating risk and the like of the previous operating method for replacement of the spacer can be solved, the working efficiency is greatly improved, and the working security of maintenance personnel is enhanced, so that the maintenance work for power-cut or live replacement of the 220kV spacer is more standardized and normalized.
