A friction pad 26 is rotatably installed at the end of the bolt 25. By providing a rotatable positioning structure 2 outside the pull rod main body 11, during the rotation of the pull rod main body 11, the pull rod main body 11 can be further positioned on the bottom plate 1 through the positioning structure 2, which can ensure the stable movement of the pull rod main body 11 and prevent the pull rod main body 11 from loosening from the bottom plate 1, thereby ensuring the use experience of the device.

[0027] Furthermore, a guiding structure 3 is installed on the bottom plate 1. The guiding structure 3 includes a fixed seat 31, which is fixedly installed on the top surface of the bottom plate 1. An activity frame 32 is movably installed inside the fixed seat 31. A buffer spring 33 is fixedly connected to the side wall of the activity frame 32. A screw rod 34 is threadedly connected to the activity frame 32. The middle part of the pull rod main body 11 is located inside the activity frame 32. Then, the screw rod 34 is screwed onto the activity frame 32. The pull rod main body 11 inside the activity frame 32 can be limited from above through the screw rod 34. When the pull rod main body 11 rotates, the pull rod main body 11 drives the activity frame 32 to move inside the fixed seat 31, and the activity frame 32 compresses the buffer spring 33 to complete buffering and reduce the damage rate of the pull rod main body 11.

[0028] Furthermore, both the fixed sleeve 21 and the rotating sleeve 22 are sleeved outside the connection part of the pull rod main body 11 and the bottom plate 1.

Rotate the bolt 25, and the bolt 25 drives the friction pad 26 to fit against the pull rod main body 11, fixing the rotating sleeve 22 on the pull rod main body 11, connecting the positioning structure 2 to the bottom plate 1, and the rotating sleeve 22 can rotate inside the fixed sleeve 21. When the pull rod main body 11 rotates, the bolt 25, the friction pad 26, and the extension plate 23 can drive the rotating sleeve 22 to rotate inside the fixed sleeve 21, enabling the movement of the pull rod main body 11 to be unrestricted and enhancing the connection stability between the pull rod main body 11 and the bottom plate 1. Then, use screws to fix the limiting block 24 on the top surface of the rotating sleeve 22. The limiting block 24 can limit the installation of the pull rod main body 11 inside the bottom plate 1 from the upper side, further enhancing the installation stability of the pull rod main body 11, effectively preventing the pull rod main body 11 from loosening from the bottom plate 1, and ensuring the use experience of the device;

[0033] The middle part of the pull rod main body 11 is located inside the movable frame 32. Then, screw the screw rod 34 onto the movable frame 32. The pull rod main body 11 can be limited inside the movable frame 32 from the upper side through the screw rod 34. When the pull rod main body 11 rotates, the pull rod main body 11 drives the movable frame 32 to move inside the fixed seat 31, and the movable frame 32 compresses the buffer spring 33 to complete buffering and reduce the damage rate of the pull rod main body 11.
