[0015] 1. In the actual operation of this utility model, personnel can suspend the safety rope inside the second U-shaped opening. By pulling the rotating stop bar, the bottom end of the rotating stop bar can abut against one side of the second U-shaped opening to form a closed space and fix the safety rope. Alternatively, excess safety rope can be suspended inside the first U-shaped opening. By pulling the rotating stop bar, the second U-shaped opening is closed, and one end of the first U-shaped opening passes through the through groove of the rotating stop bar, thus also closing the first U-shaped opening and fixing the remaining safety rope, increasing safety during use.

[0016] 2. Furthermore, after the rotating stop lever comes into contact with the inside of the second U-shaped opening, the spring telescopic rods on both sides of the first U-shaped opening will extend into the corresponding insertion holes to fix the position of the rotating stop lever. At the same time, the operator can manually press the spring telescopic rod to retract it, which can unlock the lock and make the control more convenient.

[0017] 3. While the lever is rotating, the cleaning brush at the bottom can automatically clean the dust and slag inside the second U-shaped opening, preventing some slag and dust from accumulating inside the second U-shaped opening and causing dirt to stick to it when the machine moves up and down in the mine.
