DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below with reference to the accompanying drawings.

[0025] Example 1:

[0026] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 When the cam 2 is unlocked, the cam 2 is unlocked, and the cam 2 is unlocked, so that the cam 2 can be unlocked. Figure 1 The traction rope can be installed by being sleeved on the surface of the hook 4. The positioning rod 7 and the positioning groove 6 can also be separated. After the limit rod 5 is pulled out, the traction rope and the hook 4 are slid apart to facilitate the quick installation and removal of the traction rope.

[0027] Furthermore, a fixing groove 9 is opened at one end of the connecting seat 2, and a fixing rod 10 is clamped inside the fixing groove 9. Through the setting of the fixing groove 9 and the fixing rod 10, the fixing groove 9 and the fixing rod 10 can limit the connecting seat 2 after being clamped, thereby preventing the connecting seat 2 from rotating and the connecting rod 1 from separating.

[0028] Furthermore, a spring 2 11 is provided inside the connecting rod 1, and two movable grooves 12 are opened inside the connecting rod 1. The spring 1 8 and the spring 2 11 are respectively located inside the two movable grooves 12. The setting of the spring 2 11 is used to support the fixing rod 10. The setting of the two movable grooves 12 facilitates the movement of the fixing rod 10 and the positioning rod 7.

[0029] Furthermore, the bottoms of the fixing rod 10 and the positioning rod 7 are fixedly connected with a push-pull plate 13, and the two ends of the spring 11 are fixedly connected to the connecting rod 1 and the push-pull plate 13 respectively through spring fixing parts. The setting of the push-pull plate 13 makes it convenient for users to operate the fixing rod 10 and the positioning rod 7.

[0030] Furthermore, two sliding grooves 14 are provided at the bottom of the connecting rod 1, and a slider 15 fixedly connected to the push-pull plate 13 is slidably connected inside the sliding groove 14. The setting of the sliding groove 14 and the slider 15 is used to guide the push-pull plate 13 so that it can maintain linear movement.

[0031] Furthermore, the fixing rod 10 is slidably connected to the connecting rod 1, and the positioning rod 7 is slidably connected to the connecting rod 1. The setting of the fixing rod 10 and the positioning rod 7 is used to engage with the fixing groove 9 and the positioning groove 6 respectively, thereby limiting the connecting seat 2 so that it cannot rotate, and limiting the limit rod 5 so that it cannot move upward.

[0032] Brief description of the usage process:

[0033] When in use, the connecting seat 2 connected to the threaded rod 3 is threadedly connected to the connecting rod 1, and the push-pull plate 13 connected to the fixed rod 10 is pulled toward the other push-pull plate 13, so that the fixed rod 10 enters the inside of the movable groove 12. At the same time, the push-pull plate 13 will squeeze the spring 2 11, making it in a compressed state. After the connecting seat 2 is completely tightened with the connecting rod 1, the fixed groove 9 on one side of the connecting seat 2 will correspond to the fixed rod 10. At this time, the push-pull plate 13 is released, and the spring 2 11 in a compressed state will rebound, so that the fixed rod 10 is stuck in the inside of the fixed groove 9, thereby limiting the connecting seat 2. Due to the restriction of the square structure of the fixed rod 10 and the fixed groove 9, the connecting seat 2 will not be able to rotate, and thus cannot be separated from the connecting rod 1. When the threaded rod 3 is replaced by thread slipping, the fixed rod 10 is separated from the fixed groove 9, the rotating connecting seat 2 and the connecting rod 1 are separated, and the new connecting seat 2 and threaded rod 3 are installed as described above.

[0034] See Figure 1 When the traction rope needs to be installed, the limiting rod 5 and the hook 4 are separated, the traction rope is placed on the surface of the hook 4, the limiting rod 5 is passed through the hook 4, and the positioning rod 7 is driven to squeeze the spring 1 8 by pulling the other push-pull plate 13, so that the spring 1 8 is in a compressed state. After the limiting rod 5 is fully inserted into the hook 4, the push-pull plate 13 is released, and the compressed spring 1 8 pushes the positioning rod 7 back to the inside of the positioning groove 6. If the traction rope needs to be removed, the push-pull plate 13 is pulled to separate the positioning rod 7 from the positioning groove 6, and the limiting rod 5 is pulled out, and the limiting rod 5 is slid along the hook 4 and separated from the hook 4.

[0035] It should be noted that the rebound force of spring 1 8 and spring 2 11 is respectively greater than the combined weight of the push-pull plate 13 and the fixed rod 10 and greater than the weight of the push-pull plate 13 and the positioning rod 7. In the absence of external force pushing the push-pull plate 13, the normal state of spring 1 8 and spring 2 11 is sufficient to support the fixed rod 10 and the positioning rod 7 to remain stationary.

[0036] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
