[0024] In this embodiment, the threaded rod 201 is configured so that the threaded rod 201 can drive the threaded tube 202 to be raised and lowered, and the threaded tube 202 drives the connecting plate 203 to move the subsequent locking components, thereby achieving the locking and fixing of the rope cap head, preventing the rope cap head from falling, and thus being able to automatically cut off the lock on the rope cap head, greatly improving the practicality of the overall device.

[0025] A rope cap head main body 3 is provided inside the frame 1, and two limit blocks 4 are fixedly connected to the inner wall of the frame 1. The side surfaces of the two locking plates 204 close to each other are fixedly connected with gaskets 5. By setting the rope cap head main body 3, it is easier to connect subsequent components, and the setting of the limit blocks 4 can better limit and block the rope cap head main body 3 to prevent the rope cap head main body 3 from shaking and deflecting during use, and the setting of the gasket 5 can better improve the clamping and fixing effect of the rope cap head.

[0026] Two fixed blocks 6 are fixedly connected to the upper surface of the connecting plate 203, and two sets of slide grooves 7 are opened on the inner wall of the frame 1. Two first slide bars 8 are fixedly connected to the inner walls of the two fixed blocks 6, and the first slide bars 8 are slidably connected to the inner walls of the slide grooves 7. By setting the slide grooves 7, the threaded tube 202 can be better limited and guided by the first slide bars 8, thereby avoiding the threaded tube 202 from shaking when rising and falling, thereby greatly improving the practicality of the overall device.
