The two sliding sleeves 5 are both sleeved on the surface of the guide frame 2, and a bearing plate 6 is arranged on the front side of the lifting plate 4. A movable groove 7 is opened in the middle of the surface of the bearing plate 6, and a threaded rod 8 is arranged inside the movable groove 7. An adjusting wheel 9 is arranged at one end of the threaded rod 8, and two threaded blocks 10 are symmetrically arranged on the surface of the threaded rod 8. A clamping mechanism 11 is arranged at the front end of the two threaded blocks 10. By rotating the adjusting wheel 9, the adjusting wheel 9 drives the threaded rod 8 to rotate, and the threaded rod 8 drives the two symmetrically arranged clamping mechanisms 11 to approach each other, so that the clamping mechanism can clamp and fix instrument bodies of different sizes, with a wide range of uses and good practicality.

[0025] Furthermore, the clamping mechanism 11 includes a movable plate 12 fixed at the front end of the threaded block 10, and shaft sleeves 14 are built-in at both ends of the movable plate 12. A limiting shaft 15 is arranged inside the shaft sleeve 14, and a limiting plate 13 is arranged at the end of the limiting shaft 15 away from the movable plate 12. A compression spring 16 is sleeved on the surface of the limiting shaft 15. By arranging the compression spring 16, the clamping mechanism 11 is prevented from making hard contact with the instrument, thereby protecting the instrument.

[0026] The core of the limit plate 13 includes a first limit plate 131, a second limit plate 132 and a third limit plate 133. The second limit plate 132 and the third limit plate 133 are symmetrically arranged at both ends of the outer wall of the first limit plate 131. The first limit plate 131 is a rectangular structure, and the second limit plate 132 and the third limit plate 133 are both arc-shaped structures. The first limit plate 131, the second limit plate 132 and the third limit plate 133 are a smooth transition and one-piece molding structure. The core of this part is to improve the structure of the limit plate 13 body by design, and design the outer wall of the limit plate 13 body into a two-stage arc surface structure, so that the limit plate 13 body can extend its service life in actual application.
