The lifting shackle is usually the final link in a connection chain or sling arrangement, and its main function is to establish a strong physical connection point between the load lifting equipment and the load to be moved or supported. In this embodiment, the first shackle 12 is an M12 hexagon socket D-type shackle for connecting with other equipment and is the load-bearing point of the equipment.

[0028] Preferably, the bottom of the pair of mounting plates 1 has a clearance groove 13 formed by inward depression from its lower surface, and the clearance groove 13 corresponds to the hook 3.

[0029] Please refer to Figures 2 to 3, the wrench 2 is installed on the top of a pair of mounting plates 1. One end of the wrench is located on one side of the first shackle 12, and the other end extends into the gap 11 and forms a hook 21 at the end. A second shackle 22 is installed at the end of the wrench 2 on the side of the first shackle 12. The second shackle 22 is used to connect with the pulling rope to reduce the friction of the rope. Specifically, the second shackle 22 is an M5 hexagon socket D-shaped shackle. A first central bolt 25 is provided at the connection between the wrench 2 and the pair of mounting plates 1. The first central bolt 25 sequentially penetrates through the mounting plate 1 and the wrench 2 from outside the pair of mounting plates 1. The wrench 2 rotates around the first central bolt 25 within the gap 11. The hook 21 is formed by inward depression from the lower surface of the end of the wrench 2, and its depression shape matches the shape of the hook 3.

[0030] An elastic member 23 is installed between the wrench 2 and the pair of mounting plates 1. One end of the elastic member 23 is connected to the first shackle 12, and the other end is connected to the wrench 2. Preferably, a limiting member 24 is installed on one side of the wrench 2. The limiting member 24 penetrates through the mounting plate 1 from outside the pair of mounting plates 1. When the wrench 2 is pulled by an external force, the wrench 2 rotates around the first central bolt 25. When the external force disappears, the elastic force of the elastic member 23 pulls the wrench 2 to reset, and at the same time, the wrench 2 is blocked by the limiting member 24 from moving excessively towards the first shackle 12.

[0031] Please refer to Figures 2 to 3 , the hook 3 is installed at the bottom of a pair of mounting plates 1. One end of the hook is movable within the gap 11, and the other end extends towards the outside of the gap 11 to form a counterweight portion 31.

[0032] Preferably, a hollow portion 33 is provided on one side of the hook 3. The hollow portion 33 penetrates through the hook 3 to reduce the weight of the top of the hook 3. The counterweight portion 31 extends outward from the bottom of the hook 3, and the weight of the bottom of the hook 3 is greater than the weight of the top of the hook 3.

[0033] When the hook release device for remotely releasing heavy objects of the present utility model is in use, the device is mounted with a certain amount of goods or personnel and moved to a predetermined position. When it is necessary to release the goods or personnel, the wrench 2 is pulled by an external force, such as a rope, etc. The wrench 2 rotates around the first central bolt 25, and the hook 21 is separated from the hook 3. The hook 3 is pulled by the gravity of the goods or personnel themselves, and the hook 3 rotates around the second central bolt 32, and the goods or personnel fall. Then, the hook 3 is pulled back to its original position by the counterweight portion 31. When the external force disappears, the wrench 2 is pulled back to its original position by the elastic force of the elastic member 23, and the hook 21 is re-engaged with the hook 3.

[0034] The utility model relates to a hook release device for remotely releasing heavy objects, which has the characteristics of self-resetting and long service life. By pulling the wrench with an external force, the wrench moves, the hook disengages from the hanging hook, the gravity of the goods or personnel pulls the hanging hook, and then the hanging hook is pulled back to its original position by the counterweight part, achieving the effect of self-resetting. At the same time, no wearing parts are required to participate in the direct work, improving the service life.
