Permanent magnet lifting appliance

The utility model provides a permanent magnet lifting appliance which comprises a shell, a driving mechanism and an adsorption mechanism, the driving mechanism and the adsorption mechanism are arranged in the shell, the adsorption mechanism is located at the bottom of the shell, and the adsorption mechanism comprises two magnetic suction units oppositely arranged in the length direction of the shell and a variable magnetic mechanism used for changing the magnetic force of the adsorption mechanism. The two magnetic attraction units are both fixed to the bottom of the shell, a rotating space around which the variable magnetic mechanism rotates is formed between the two magnetic attraction units in a spaced mode, the variable magnetic mechanism is arranged in the rotating space and rotatably connected to the shell, and the driving end of the driving mechanism is fixedly connected with the variable magnetic mechanism. According to the structure, a technician does not need to lock a steel wire rope for cutting hea
