The unhooking assembly includes: a biting tooth 2, a transmission tooth 21 and a rack plate 22, and an installation assembly is arranged on the housing 1 and used to connect the suspension rope 15. The installation assembly includes: a guide rod 3, a pressing block 31, a friction block 32, a threaded hole 33 and a top bolt 34.

[0027] During use, the suspension rope 15 is connected to the housing 1 through the installation assembly, the buckle 13 is controlled to open through the unhooking assembly, the steel cable for lifting the goods is hung on the hook 11, and then the buckle 13 is controlled to close to prevent the steel cable from falling off. After the goods are transported to the destination, the goods first land and the buckle 13 is controlled to open. Subsequently, the hook 11 moves downward and moves to the side opposite to the buckle 13, so that the steel cable is disengaged from the hook 11, thereby completing the unhooking operation. When lifting the goods, the hook 11 is controlled to move to the steel cable of the goods, so that the steel cable is clamped on the hook 11, and then the buckle 13 is controlled to close, thereby completing the hooking of the goods.

[0028] Embodiment 2

[0029] On the basis of Embodiment 1, the higher end of the buckle 13 is arranged in an arc-shaped structure, and a number of equally spaced biting teeth 2 are fixedly connected to the outside of the arc-shaped structure of the buckle 13. A rotating cavity communicating with the outside is formed inside the hook 11, a transmission tooth 21 is rotatably connected inside the rotating cavity, the transmission tooth 21 is in biting connection with the biting tooth 2, a moving groove communicating with the rotating cavity is formed inside the hook 11, a rack plate 22 is arranged inside the moving groove, the rack plate 22 is in biting connection with the transmission tooth 21, a threaded rod 23 is arranged inside the moving groove, both ends of the threaded rod 23 are rotatably connected between the opposite inner walls of the housing 1, a threaded block 24 is threadedly connected to the outside of the threaded rod 23, the bottom of the threaded block 24 is connected to the rack plate 22, a motor 25 is fixedly installed on one side of the housing 1, the driving shaft of the motor 25 is in transmission connection with one end of the threaded rod 23, and two stroke switches 26 are respectively fixedly installed on the opposite inner walls of the housing 1, and the two stroke switches 26 are on the same horizontal plane as the threaded block 24.

[0030] When controlling the opening and closing of the buckle 13, the motor 25 is started through the remote control device of the drone. The motor 25 is a forward and reverse motor and its rotation mode can be switched through the remote control device. When the motor 25 rotates, it drives the threaded rod 23 to rotate. The threaded rod 23 rotates and is screwed with the threaded block 24. Since the threaded block 24 is restricted by the moving groove, the threaded block 24 can only move in the horizontal direction. Therefore, when the threads are screwed together, the threaded block 24 will be driven to move. The threaded block 24 drives the rack plate 22 to move. The rack plate 22 moves and meshes with the transmission gear 21, thereby driving the transmission gear 21 to rotate. The transmission gear 21 rotates and meshes with the engaging teeth 2 outside the buckle 13, thereby driving the buckle 13 to rotate. When the buckle 13 rotates, one end of it moves inside the movable groove 14. By controlling the rotation direction of the motor 25, the opening and closing of the buckle 13 can be controlled. When the threaded block 24 touches the travel switch 26 on the moving side during movement, the motor 25 stops working, thereby restricting the maximum moving distance of the threaded block 24.

[0031] Embodiment 3

[0032] On the basis of Embodiment 1, an installation groove is opened at the top of the housing 1. A guide rod 3 is fixedly connected between the inner walls on the opposite sides of the installation groove. A pressing block 31 is slidably connected to the outside of the guide rod 3. One side of the pressing block 31 is fixedly connected with two symmetrically arranged friction blocks 32. A threaded hole 33 communicating with the inside of the installation groove is opened on one side of the housing 1. A top bolt 34 is threadedly connected to the inside of the threaded hole 33. One end of the lifting rope 15 bypasses the guide rod 3 and extends from the inside of the installation groove to the outside. Guide blocks 35 are respectively fixedly connected to the opposite sides of the pressing block 31. Guide grooves 36 matching the guide blocks 35 are respectively opened on the inner walls on the opposite sides of the installation groove. The two guide blocks 35 are respectively located inside the two guide grooves 36. A spring 37 is sleeved outside the top bolt 34. One end of the spring 37 is in contact with the nut of the top bolt 34, and the other end of the spring 37 is in contact with the housing 1.

[0033] When connecting the lifting rope 15, the bottom end of the lifting rope 15 is bypassed around the guide rod 3 and extends out from the installation groove. Then, the top bolt 34 is rotated by a wrench to screw the top bolt 34 into the threaded hole 33. One end of the top bolt 34 extends into the installation groove and pushes the pressing block 31 to move. The pressing block 31 is restricted by the two guide blocks 35 and the guide grooves 36 on both sides, so as to support the pressing block 31 and make it move only on the horizontal line of the guide groove 36. The pressing block 31 clamps the lifting rope 15, and the pressing block 31 can improve the friction force. When the top bolt 34 is screwed in, it will compress the spring 37, causing the spring 37 to contract and store energy. Under the elastic force of the spring 37, the loosening of the top bolt 34 can be avoided, thereby fixing the lifting rope 15 and completing the connection.
