[0023] Working principle of the utility model: when using the utility model, two sets of auxiliary connecting lock hooks 226 are installed on the upper end of the object that needs to be lifted. After the hook 214 is installed, the front automatic reel 213 is started to lift the object. After the hook 214 completes the lifting work, when the problem of the wire rope falling off occurs during the lifting process, the two sets of auxiliary connecting lock hooks 226 can assist in hooking and lifting the upper end of the side of the object to avoid the problem of the material falling directly. When the auxiliary connecting lock hook 226 needs to be tightened during work, the electric hydraulic cylinder 222 can be started. After the electric hydraulic cylinder 222 is started, the pushing block 223 at the output end is driven to move backward. After the pushing block 223 moves backward, the two sets of auxiliary connecting lock hooks 226 are moved to the front end of the upper automatic wire rope tightener 228 and the lower automatic wire rope tightener 229. The upper automatic wire rope tightener 228 and the lower automatic wire rope tightener 229 are closed to tighten and fix the wire ropes at the upper ends of the two sets of auxiliary connecting lock hooks 226.
