One end of the multiple limit blocks 14 close to the limit block grooves 15 is in contact with the inner wall of the corresponding limit block grooves 15. The lower surface of the fixed seat 12 is fixedly connected to the upper surface of the sliding seat 4. The upper surface of the rotating seat 7 is fixedly connected to two fixed blocks 9. The outer walls of the two fixed blocks 9 are threadedly connected to the rotating threaded rod 6. Multiple grooves are provided on the upper surface of the seat 12, and return springs 13 are provided inside. The two ends of the multiple return springs 13 are respectively fixedly connected to the inner wall of the groove provided on the upper surface of the corresponding fixed seat 12 and one end of the limit block 14. Two clamping blocks 5 are provided on the opposite surfaces of the two fixed blocks 9. The ends of the two rotating threaded rods 6 close to the clamping block 5 are threadedly extended to the outside of the fixed block 9 and are respectively rotatably connected to the outer wall of the corresponding rotating threaded rod 6. The ends of the two sliding rods slidably connected to the outer walls of the two fixed blocks 9 are slidably extended to the outside of the fixed block 9 and are respectively fixedly connected to the outer wall of the corresponding clamping block 5.

[0033] Among them, four dampers 11 are installed on the upper surface of the base 1, and the four dampers 11 are respectively located at the four corners of the base 1; a support seat 10 is provided on the upper end of the base 1, and the lower surface of the support seat 10 is fixedly connected to the end of the damper 11 away from the base 1; the upper surfaces of the left and right sides of the support seat 10 are fixedly connected to support columns 2, and the outer walls of the two support columns 2 are provided with grooves and the interiors are rotatably connected to threaded rods 16, and the two ends of the sliding seat 4 are respectively threadedly connected to the outer walls of the corresponding threaded rods 16, and the two threaded rods 16 close to the end of the base 1 are rotated to extend to the outside of the support seat 10 and are fixedly connected to the transmission wheel 18, and the outer walls of the two transmission wheels 18 are connected with a transmission belt 17 for transmission.

[0034] Furthermore, when using the device, it is started by connecting an external power supply, first placing the optical lens in the middle of the two clamping blocks 5, then rotating the threaded rod 6 to move toward the clamping block 5 while driving the clamping block 5 to move in the opposite direction, then clamping and fixing the optical lens by the clamping block 5, then rotating the output end of the motor 3 to drive the left threaded rod 16 to rotate while driving the right threaded rod 16 to rotate through the transmission belt 17 and the transmission wheel 18, then rotating the threaded rod 16 to drive the sliding seat 4 up and down while driving the clamping block 5 up and down to adjust the detection height of the optical lens, then the damper 11 can absorb the force acting on the support seat 10 as needed, relieve the force acting on the support seat 10 to achieve shock absorption of the equipment.

The output end of the motor 3 rotates to drive the left threaded rod 16 to rotate, and at the same time, the transmission belt 17 and the transmission wheel 18 cooperate to drive the right threaded rod 16 to rotate. Then the threaded rod 16 rotates to drive the sliding seat 4 to move up and down, and at the same time, drive the clamping block 5 to move up and down to adjust the detection height of the optical lens. This makes it easy to adjust the height of the optical lens, improves the practicality and flexibility of the equipment, and improves the work efficiency of the staff.

[0037] Working principle: First, place the optical lens in the middle of the two clamping blocks 5, then rotate the rotating threaded rod 6 to move in the direction of the clamping block 5 while driving the clamping block 5 to move in the opposite direction, then clamp and fix the optical lens through the clamping block 5, then rotate the output end of the motor 3 to drive the left threaded rod 16 to rotate while driving the right threaded rod 16 to rotate through the transmission belt 17 and the transmission wheel 18, then the threaded rod 16 rotates to drive the sliding seat 4 up and down while driving the clamping block 5 up and down to adjust the detection height of the optical lens, then when needed, the damper 11 can absorb the force acting on the support seat 10, alleviate the force acting on the support seat 10 to achieve shock absorption of the equipment, then when the angle of the optical lens needs to be adjusted, the force generated by the rotation of the rotating seat 7 makes multiple limit blocks 14 contact with the inner walls of different limit block grooves 15 respectively, and at the same time, the force generated by the contraction and expansion of multiple reset springs 13 resets the limit block 14, so that there is a pause when adjusting the angle, thereby improving the accuracy of the measurement results.
