1) The first magnetic attraction piece is provided with a first control switch, the second magnetic attraction piece is provided with a second control switch, and the first control switch and the second control switch are connected with the driving piece to control the working state of the driving piece;
2) When the equipment works, the first control switch and the first magnetic attraction piece are opened, the second control switch and the second magnetic attraction piece are opened, the driving piece can be normally started, one part of the first control switch and the second control switch does not work, and the driving piece does not work;
3) When the equipment is stopped, the first magnetic attraction piece drives the locking piece to move towards the tooth position of the first gear, and the locking piece is meshed with the first gear tooth to limit the rotation of the winding wheel, so that the lifting assembly is locked at a stopping point;
4) The lifting disc rod ascends and touches the limiter, the second magnetic attraction piece drives the locking piece to move into the groove locking cap of the lifting disc rod to lock, and the locking piece and the lifting disc rod provide supporting force for the lifting assembly, so that the steel wire rope is in a non-stressed hanging state;
5) When the equipment descends, the winding wheel slightly lifts the lifting assembly, the first magnetic attraction piece drives the locking piece to separate the tooth position of the first gear, the second magnetic attraction piece drives the locking piece to move away from the groove locking cap, and then the winding wheel releases the steel wire rope, so that the lifting assembly descends.
