The personnel press the two plates 62 inward at the same time, the spring structure 65 contracts, and the telescopic rod 61 moves into the circular hole 64. The personnel turn the outer end of the L-shaped plate 51 upward to the maximum position, and the inner end of the L-shaped plate 51 is located in the hook 41, so that the hook 41 is opened. At the same time, the personnel releases the plate 62, and the spring structure 65 contracts. The structure 65 is extended, the telescopic rod 61 moves outward, and the telescopic rod 61 abuts against the lower side of the outer end of the L-shaped plate 51 to prevent the L-shaped plate 51 from rotating when the hook 41 hooks the wire rope, without affecting the lifting work of the personnel. After the personnel hook the hook 41 onto the wire rope, the personnel move the plate body 62 inward, the spring structure 65 contracts, and the telescopic rod 61 moves inward.
