The head of the adjusting bolt 6 is sleeved with a gasket 7 and a spring washer 8. The gasket 7 can disperse the pressure of the head of the adjusting bolt 6 and protect the surface of the component in contact with it.The spring washer 8 can prevent the adjusting bolt 6 from loosening due to vibration and other reasons during use. The outer wall of the adjusting bolt 6 is arranged through the locking block 4 and the locking seat 5. By rotating the adjusting bolt 6, the locking block 4 and the locking seat 5 can be moved or fixed in the guide rail 1.

The outer wall of the fourth wedge 14 is The fifth wedge 15 is fitted on the side, and the fitting relationship between these wedges forms a coherent force transmission and locking mechanism. The inner wall of the second wedge 12 is threadedly connected to the outer wall of the adjusting bolt 6. When the adjusting bolt 6 is rotated, the second wedge 12 can be driven to slide on the guide rail 1, thereby triggering a series of chain reactions to achieve locking or loosening operations. The third slider 24 is provided with a left-right symmetrical first limit pin 16. The two first limit pins 16 are used to limit the sliding range of the third slider 24 in the guide rail 1 so that it can only move within a specified direction and range. The outer walls of the two first limit pins 16 are slidably connected to one side of the inner part of the guide rail 1, and the first slider 9 is provided with a second limit pin 17. The second limit pin 17 is for the first slider The sliding movement of block 9 within guide rail 1 acts as a limiter, ensuring the accuracy and stability of its movement. The outer walls of two second limit pins 17 are slidably connected to the inner middle side of guide rail 1. A third limit pin 18 is provided through one side of the interior of the second slider 10, limiting the sliding direction and range of the second slider 10 within the guide rail 1. The outer wall of the third limit pin 18 is slidably connected to the other side of the interior of the guide rail 1. A first limit slot 19 is provided through one side of the interior of the fifth wedge 15. The outer wall of a first limit pin 16 is slidably connected to the inner wall of the first limit slot 19.
