[0028] Embodiment 1: An optical lens positioning structure, including a base 1. The front end of a connecting rod 7 is fixedly connected with a positioning housing 8. The inner wall of the top end of the positioning housing 8 is rotatably connected with a rotating shaft 10. The bottom end of the rotating shaft 10 is fixedly connected with a small gear 11. The opposite ends of a second sliding tooth plate 15 are fixedly connected with positioning plates 16. The inner wall of an outer tooth ring 12 is fixedly connected with an inner tooth ring 13. The inner walls of the four sides of the inner tooth ring 13 are all meshed with long gears 14. The outer walls of the second sliding tooth plates 15 are meshed on the upper side of the outer diameter of the long gears 14 in the clockwise direction. The top end of the rotating shaft 10 is fixedly connected with a second knob 9. The bottom end of the small gear 11 is rotatably connected with the inner wall of the bottom end of the positioning housing 8. The bottom ends of the outer tooth ring 12 and the inner tooth ring 13 are both rotatably connected with the inner wall of the bottom end of the positioning housing 8. The upper and lower ends of the long gears 14 are respectively rotatably connected with the upper and lower inner walls of the positioning housing 8. The top ends of the second sliding tooth plates 15 are slidably connected with the inner wall of the top end of the positioning housing 8.

[0029] Specifically, first place the optical lens in the middle of the positioning housing 8, and then rotate the second knob 9. The second knob 9 drives the rotation shaft 10 to rotate, the rotation shaft 10 drives the small gear 11 to rotate, the small gear 11 drives the outer tooth ring 12 to rotate, the outer tooth ring 12 drives the inner tooth ring 13 to rotate, and the rotation of the inner tooth ring 13 drives the long gears 14 on the four sides of the inner diameter to rotate.

Finally, the positioning of optical lenses of different specifications is achieved, which has strong flexibility, strong adaptability, and can provide stable support and fixation to maintain the stability of the lens during processing.

[0030] Embodiment 2: A support column 2 is fixedly connected to the rear side of the top end of the base 1.

[0031] Specifically, when it is necessary to adjust the angle of the fixed optical lens, the first knob 3 can be rotated. The first knob 3 drives the threaded rod 4 to rotate, the threaded rod 4 drives the first sliding tooth plate 5 to move, the first sliding tooth plate 5 drives the half gear 6 to rotate, and the half gear 6 drives the connecting rod 7 to rotate, thereby driving the entire positioning housing 8 to rotate, so that the fixed optical lens can adjust the angle, facilitating the worker to process the optical lens at different angles and improving work efficiency.

[0032] Working principle: During use, first place the optical lens in the middle of the positioning housing 8, and then rotate the second knob 9. The second knob 9 drives the rotation shaft 10 to rotate, thereby driving the small gear 11 to rotate, thereby driving the outer tooth ring 12 to rotate, and further driving the inner tooth ring 13 to rotate. The rotation of the inner tooth ring 13 drives the long gears 14 on the four sides of the inner diameter to rotate, thereby driving the second sliding tooth plates 15 on the four sides to move inward, thereby driving the positioning plate 16 to clamp the optical lens, so that the optical lens does not shake during processing. Then, the first knob 3 can be rotated. The first knob 3 drives the threaded rod 4 to rotate, thereby driving the first sliding tooth plate 5 to move, the first sliding tooth plate 5 drives the half gear 6 to rotate, and the half gear 6 drives the connecting rod 7 to rotate, thereby driving the entire positioning housing 8 to rotate, facilitating the worker to process the optical lens at different angles and improving work efficiency.
