[0022] In this embodiment: when installing the imaging device 15, the imaging device 15 is placed above the base plate 3 between the two clamping blocks 10, and then the threaded rod 18 is rotated. The threaded rod 18 drives the second fixed block 17 to move upward, and then drives the base plate 3 and the first sliding rod 5 to move upward along the sleeve 4. The base plate 3 further drives the two sliding blocks 9 and the two clamping blocks 10 to move upward, and then the two clamping blocks 10 are squeezed inward by the squeezing block 12. The two clamping blocks 10 slide relative to each other to clamp and fix the imaging device 15. While the base plate 3 moves upward, it drives the imaging device 15 upward against the lower end surface of the pressure plate 14, thereby limiting the imaging device 15 in the vertical direction. The imaging device 15 can be fixed from four directions: front, back, left and right through the relative sliding of the two clamping blocks 10. The imaging device 15 can be fixed in the vertical direction through the pressure plate 14 and the base plate 3. The fixing is firm and the installation is convenient.

[0025] As a technical optimization solution of the present invention, the outer wall of the second slide bar 7 is sleeved with a first spring 8 located between two slide blocks 9 .

[0026] In this embodiment, the elastic force of the first spring 8 facilitates the two sliding blocks 9 and the clamping block 10 to slide to both sides.

[0033] The working principle and use process of the utility model are as follows: when installing the imaging device 15, first place the imaging device 15 above the base plate 3 between the two clamping blocks 10, and then rotate the threaded rod 18. The threaded rod 18 drives the second fixed block 17 to move upward, and then drives the base plate 3 and the first sliding rod 5 to move upward along the sleeve 4. The base plate 3 further drives the two sliding blocks 9 and the two clamping blocks 10 to move upward, and then the two clamping blocks 10 are squeezed inward by the squeezing block 12. The two clamping blocks 10 slide relative to each other to clamp and fix the imaging device 15. While the base plate 3 moves upward, it drives the imaging device 15 upward against the lower end surface of the pressure plate 14, thereby limiting the imaging device 15 in the vertical direction. The imaging device 15 can be fixed in four directions from front to back, left to right, and the relative sliding of the two clamping blocks 10 can fix the imaging device 15 in four directions. The imaging device 15 can be fixed in the vertical direction by the pressure plate 14 and the base plate 3. The fixation is firm and the installation is convenient.
