[0040] When the cargo needs to be lifted, the protective plate is rotated to drive the fixing block 4 and the fixing member 5 to rotate. When the fixing member 5 reaches a suitable position, the fixing member 5 is pushed. The fixing member 5 drives the fixed baffle 703 to move on the surface of the limit column 701 and squeezes the fixing spring 702. The fixed baffle 703 drives the control block 704 to move. The control block 704 drives the control link 807 to rotate. The control link 807 drives the control plate 806 to move. The control plate 806 drives the control member 805 and the control gear 804 to rotate synchronously. The control gear 804 drives the control rack 803 to move on the surface of the support column 802. The control rack 803 drives The control switch 801 moves. When the fixing part 5 enters, the force released by the fixing spring 702 after being squeezed pushes the fixed baffle 703 to move in the opposite direction on the surface of the limit column 701. The fixed baffle 703 drives the control block 704 to move in the opposite direction. The control block 704 drives the control link 807 to rotate in the opposite direction. The control link 807 drives the control plate 806 to move in the opposite direction. The control plate 806 drives the control part 805 and the control gear 804 to rotate in the opposite direction synchronously. The control gear 804 drives the control rack 803 to move in the opposite direction on the surface of the support column 802. The control rack 803 drives the control switch 801 to move in the opposite direction and reset, thereby completing the fixation.

[0041] In summary: the anti-slip structure for the crane hook, through the coordinated use of the protective plate, the fixing block 4, the fixing part 5, the fixing device 7 and the control device 8, solves the problem that when the existing crane is lifting the goods, the hook may shake, causing the goods to fall off the hook, causing the goods to fall directly to the ground and the goods themselves to be damaged.
