[0029] Please refer to Figures 1-3 , the present utility model provides a technical solution: an optical lens fixture that is easy to adjust, including a mounting base 1;

[0030] A limiting device is provided on the mounting base 1;

[0031] The limiting device includes a sliding seat 9, a protective pad 5 and a rotating rod 8. One end of the rotating rod 8 is threadedly connected to the outer wall of the sliding seat 9. A clamping plate 6 is provided outside the sliding seat 9. The clamping plate 6 is arc-shaped. Two guide blocks 15 are fixedly connected to the outer wall of the protective pad 5. One end of the rotating rod 8 close to the sliding seat 9 extends threadedly outside the sliding seat 9 and is rotatably connected to the outer wall of the clamping plate 6. A telescopic rod 4 is fixedly connected to the inner wall of the sliding seat 9. One end of the telescopic rod 4 away from the sliding seat 9 is fixedly connected to the outer wall of the clamping plate 6. Two sliding block grooves 14 are opened on the inner wall of the clamping plate 6. The outer walls of the two guide blocks 15 are respectively slidably connected to the inside of the corresponding sliding block grooves 14. Sliding blocks 13 are slidably connected to the inside of the two sliding block grooves 14. The outer walls of the two sliding blocks 13 are respectively in contact with the outer walls of the corresponding guide blocks 15. Threaded holes are opened on the outer wall of the end of the clamping plate 6 away from the protective pad 5, and two fixing bolts 7 are threadedly connected to the inside of the threaded holes. One end of each of the two fixing bolts 7 close to the sliding block 13 extends threadedly into the inside of the sliding block groove 14 and is respectively threadedly connected to the inside of the groove opened on the outer wall of the corresponding sliding block 13. There are two handles 2 in total for the limiting device, and both limiting devices are provided on the mounting base 1.

[0032] Among them, a sliding seat groove 3 is formed on the outer wall of the mounting seat 1. The outer walls of the two sliding seats 9 are both slidably connected to the inside of the sliding seat groove 3. A bidirectional threaded rod 16 is rotatably connected inside the mounting seat 1. Both sliding seats 9 are threadedly connected to the outer wall of the bidirectional threaded rod 16. A hand crank 11 is rotatably connected to the outer wall of the mounting seat 1. One end of the hand crank 11 close to the bidirectional threaded rod 16 rotatably extends into the inside of the sliding seat groove 3 and is fixedly connected to one end of the bidirectional threaded rod 16. Two handles 2 are fixedly connected to one end of the mounting seat 1 away from the clamping plate 6. A limiting groove 17 is formed inside the sliding seat groove 3. The outer walls of the two sliding seats 9 away from the protective pad 5 are both slidably connected to the inside of the limiting groove 17. A fixing rod 12 is slidably connected to the outer wall of the fixed block on the outer wall of the hand crank 11. Two fixing rod grooves 10 are formed on the outer wall of the mounting seat 1 close to the hand crank 11. One end of the fixing rod 12 close to the fixing rod groove 10 slidably extends outside the fixed block on the outer wall of the hand crank 11 and contacts the inner wall of the corresponding fixing rod groove 10.

[0033] Further, when using this device, it is started by connecting to an external power supply. First, remove the fixing rod 12 on the hand crank 11 and then rotate the hand crank 11. While rotating the hand crank 11 to drive the bidirectional threaded rod 16 to rotate, it also drives the sliding seats 9 to move in opposite directions. While the sliding seats 9 move in opposite directions, the limiting groove 17 is used to limit their rotation to prevent them from rotating. Then, adjust the distance between the two sliding seats 9 according to the size of the optical lens. After adjustment, insert the fixing rod 12 through the fixed block on the hand crank 11 into the inside of the fixing rod groove 10 to limit the hand crank 11. Then, place the optical lens on the opposite surfaces of the two protective pads 5 and then rotate the rotating rod 8 and move it in the direction of the sliding seat 9 at the same time to drive the clamping plate 6 to move in the opposite direction. Then, while the clamping plate 6 moves in the opposite direction, the telescopic rod 4 is used to limit its rotation to prevent it from rotating, and at the same time, it drives the protective pad 5 to clamp the optical lens.

[0034] Further, when it is necessary to remove the protective pad 5, after unscrewing the fixing bolt 7 to remove it, slide the sliding block 13 to limit it, and then it can be taken out from the inside of the sliding block groove 14. Then, the guiding block 15 on the protective pad 5 is used to limit the sliding block 13, and then the protective pad 5 and the guiding block 15 can be removed from the clamping plate 6.

[0035] After removing it by turning and fixing the bolt 7 in the limiting device, the slider 13 can be limited to take it out from the inside of the slider groove 14. Then, the guide block 15 on the protective pad 5 can limit the slider 13 to remove the protective pad 5 and the guide block 15 from the clamping plate 6. This facilitates the removal of the protective pad 5, avoids the need for the staff to remove the entire clamping plate 6, effectively reduces the workload of the staff, and improves the removal efficiency of the protective pad 5. After removing the fixed rod 12 on the rocking handle 11 and rotating the rocking handle 11, the bidirectional threaded rod 16 rotates, driving the sliding seat 9 to move in the opposite direction at the same time. While the sliding seat 9 moves in the opposite direction, it is limited by the limiting groove 17 to prevent it from rotating. Then, the distance between the two sliding seats 9 is adjusted according to the size of the optical lens. This facilitates the pre-adjustment of the distance between the sliding seats 9, effectively improves the practicability and flexibility of the device, and at the same time realizes the pre-adjustment of the distance of the protective pad 5, improving the working efficiency of the device.

[0036] Working principle: First, remove the fixed rod 12 on the rocking handle 11 and rotate the rocking handle 11. The rotation drives the bidirectional threaded rod 16 to rotate, driving the sliding seat 9 to move in the opposite direction at the same time. While the sliding seat 9 moves in the opposite direction, it is limited by the limiting groove 17 to prevent it from rotating. Then, the distance between the two sliding seats 9 is adjusted according to the size of the optical lens. After adjustment, insert the fixed rod 12 into the inside of the fixed rod groove 10 through the fixed block on the rocking handle 11 to limit the rocking handle 11. Then, place the optical lens on the opposite faces of the two protective pads 5 and turn the rotating rod 8 while moving it in the direction of the sliding seat 9, driving the clamping plate 6 to move in the opposite direction. Then, as the clamping plate 6 moves in the opposite direction, it is limited by the telescopic rod 4 to prevent it from rotating, and at the same time drives the protective pad 5 to clamp the optical lens. Then, when it is necessary to remove the protective pad 5, turn and fix the bolt 7 to remove it, and the slider 13 can be limited to take it out from the inside of the slider groove 14. Then, the guide block 15 on the protective pad 5 can limit the slider 13 to remove the protective pad 5 and the guide block 15 from the clamping plate 6.
