DETAILED DESCRIPTION

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 In this utility model, an easy-to-install trailer hook includes a base 1 and a plug rod 9. A fixing frame 2 is fixedly connected to the upper surface of the base 1. A connecting rod 6 is threadedly connected to the inside of the fixing frame 2. A first nut 7 is threadedly connected to the left end of the connecting rod 6. The right side of the first nut 7 contacts the left side of the fixing frame 2. A symmetrical first pin 19 is fixedly connected to the outer surface of the fixing frame 2. A rotating plate 4 is hinged to the outer surface of each of the two first pins 19. A second pin 20 is fixedly connected to the side of the two rotating plates 4 that is close to each other. A rotating rod 11 is hinged to the outer surface of the second pin 20. Insertion holes 3 are provided on the outer surfaces of the two rotating plates 4 and the outer surfaces of the rotating rod 11. The insertion holes 3 are adapted to the plug rod 9. The upper surface of the base 1... The device has symmetrical mounting holes 17. Bolts 14 are slidably connected inside both sets of mounting holes 17. Second nuts 16 are threaded onto the outer surfaces of both sets of bolts 14. Through the cooperation of the fixing frame 2, the connecting rod 6 and the first nut 7, the connecting rod 6 can replace the hook. When the trailer hook is damaged, it is not necessary to replace the entire trailer hook. Through the cooperation of the fixing frame 2, the rotating plate 4 and the rotating rod 11, the rope wrapped on the connecting rod 6 can be positioned to prevent the rope from falling off the connecting rod 6. Through the cooperation of the insertion hole 3 and the insertion rod 9, the rotating rod 11 can be positioned to prevent the rotating rod 11 from shifting and causing the rotating plate 4 to lose its positioning function. Through the cooperation of the bolts 14 and the second nut 16, the device can be easily installed and disassembled.

[0021] A hanging ring 10 is fixedly connected to the front of the fixing frame 2. A connecting rope 8 is wound around the outer surface of the hanging ring 10. A plug rod 9 is fixedly connected to the left end of the connecting rope 8. A positioning plate 18 is fixedly connected to the outer surface of the connecting rod 6. The left side of the positioning plate 18 contacts the right side of the fixing frame 2. A ball 5 is fixedly connected to the right end of the connecting rod 6. The outer surface of the ball 5 contacts the outer surface of the rotating rod 11. The cooperation of the hanging ring 10 and the connecting rope 8 facilitates the connection of the plug rod 9 and prevents the plug rod 9 from being lost. The cooperation of the positioning plate 18 and the fixing frame 2 facilitates the positioning of the installation position of the connecting rod 6. The ball 5 provides resistance to the rope wound around the connecting rod 6, thus limiting its movement.

[0022] A symmetrical positioning rod 12 is fixedly connected to the outer surface of the rotating rod 11. Positioning grooves 13 are provided on the right side of both rotating plates 4. Both positioning rods 12 are adapted to the positioning grooves 13. Washers 15 are provided on the outer surface of both sets of bolts 14. The upper surface of both sets of washers 15 is in contact with the bottom surface of the base 1, and the bottom surface of both sets of washers 15 is in contact with the upper surface of the second nut 16. Through the cooperation of the positioning rods 12 and the positioning grooves 13, the rotating rod 11 can be limited. By providing washers 15, the friction can be increased to prevent the second nut 16 from loosening with the bolts 14.

[0023] The working principle of this utility model is as follows:

[0024] In use, the user first installs the base 1 onto the frame using the bolt 14, the second nut 16, and the washer 15. Then, the rope is wound around the connecting rod 6. Next, the rotating plate 4 is rotated to contact the ball 5. Then, the rotating rod 11 is rotated between the two rotating plates 4, and the rotating rod 11 contacts the fixing frame 2 to position the rotating plate 4. Finally, the insert rod 9 is inserted into the insertion hole 3 to position the rotating rod 11, thereby preventing the rope from falling off. When the connecting rod 6 is damaged, the first nut 7 is rotated to separate it from the connecting rod 6. Then, the damaged connecting rod 6 can be separated from the fixing frame 2 for replacement.
