The outer ring of the bearing is embedded in the inner groove of the intermediate seat, which has a center positioning line, rotating grooves on both sides, and a threaded hole at the bottom. The rotating dial is embedded in the inner ring of the bearing and locked in place by the locking screws. This technical solution is simple in structure, compact in size, easy to install, and provides precise adjustment, making it highly practical and effectively meeting the needs of optical path adjustment. However, while this solution achieves adjustment, it is inconvenient for the quick disassembly and fixation of optical components, resulting in inconvenience during use. Utility Model Content

This utility model has a novel structure. In use, the movable seat is opened to one side, and after the movable seat is opened, the optical sheet is installed between the movable columns. The movable columns are supported by a crossbar. The movable columns are pushed to move according to the diameter of the optical sheet, and the movable columns clamp and fix the optical sheet through the reverse force, which facilitates quick installation in the early stage.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 6This utility model provides a technical solution: an optical rotation adjustment bracket, including a base 1, a support tube 2 welded to the base 1, a connecting column movably installed inside the support tube 2, a fixing column 3 fixed to one end of the connecting column, a fixing seat 4 fixedly installed on the fixing column 3, a fixing plate 5 welded to the side of the fixing seat 4, a rotating shaft 6 rotatably installed between the fixing plates 5, a fastening bolt 7 rotatably installed between the rotating shaft 6 and the fixing plate 5, a threaded tube 8 fixed to the rotating shaft 6, and a rotatably installed inside the threaded tube 8. The threaded post 9 has a ring seat 10 movably mounted at one end of the fixed post 3. A fixed frame 11 is fixed to the top of the ring seat 10. A support plate 12 is welded to the top of the fixed frame 11. A fixing assembly 13 is movably mounted between the support plates 12. The fixing assembly 13 includes a support frame 19. The support frame 19 has an annular groove. A rubber ring 20 is fixed to the inner wall of the annular groove. The rubber ring 20 will later come into contact with one end of the fixed insert 18 to generate a squeezing friction force. The squeezing friction force limits and fixes the support frame 19 to prevent rotation from causing any impact.

[0026] In this embodiment, a limiting cavity 21 is formed on the side of the annular groove, and a limiting groove 14 is formed on the support plate 12. A limiting block 16 is movably installed inside the limiting groove 14, and a limiting post 17 is fixed on the limiting block 16. One end of the limiting post 17 is movably installed inside the limiting cavity 21. A support mechanism 15 is fixed between the limiting block 16 and the limiting groove 14. An installation hole is formed on the inner wall of the support frame 19, and a movable post 23 is movably installed inside the installation hole. A crossbar is fixed on the side of the movable post 23. An optical plate 31 is movably installed between the movable column 23 and the movable column 23. A reset mechanism 29 and a positioning component 30 are fixed inside the mounting hole. One end of the positioning component 30 and the reset mechanism 29 are both fixed to one end of the movable column 23. A positioning column 24 is fixed to the side of the support frame 19. A tension mechanism 25 is fixed to one end of the positioning column 24. The support mechanism 15, the reset mechanism 29 and the tension mechanism 25 are all springs. When the support frame 19 moves downward under the push of the support mechanism 15, it contacts the fixed insertion 18 for limiting and fixing.

[0027] In this embodiment, movable seats 22 are movably mounted at both ends of the support frame 19. Fixing holes 27 are formed on the sides of the movable seats 22. Positioning pins 24 are installed inside the fixing holes 27 via a tension mechanism 25. A lens 26 is fixed inside the movable seats 22. A pressing pin 28 is fixed on the inner wall of the lens 26. One end of the pressing pin 28 is movably mounted inside the support frame 19. A sliding groove 32 is formed on the side of the fixing pin 3, and a return mechanism 3 is fixed inside the sliding groove 32. 4. One end of the repositioning mechanism 34 is fixed with a slider 33, which is fixed on the inner wall of the ring seat 10. One end of the fixing post 3 is fixed with a fixing insert 18. The fixing frame 11 has a through hole, and the fixing insert 18 moves and contacts the rubber ring 20 through the through hole. The repositioning mechanism 34 is a spring. Under the drive of the spring, the fixing frame 11 always moves downward. When the fixing frame 11 is movably installed on the fixing post 3, it avoids damage caused by excessive compression of the rubber ring 20 by the fixing insert 18.

[0028] Working principle: In use, place the base 1 at the point of use, and rotate the fastening bolt 7 until it is loose. After the fastening bolt 7 is loosened, the rotating shaft 6 loses its clamping and limiting force, and the threaded tube 8 rotates through the rotating shaft 6. The rotation of the threaded tube 8 controls the tilt angle, and the threaded column 9 rotates inside the threaded tube 8. After the threaded column 9 rotates, it contacts both sides of the base 1. The threaded column 9 and the base 1 cooperate to provide multi-point support to ensure the stability of the base 1. The optical plate 31 is installed inside the support frame 19. First, the movable seat 22 is moved to one side. During movement, the positioning post 24 pulls the tension mechanism 25 to move inside the fixing hole 27. After the movable seat 22 opens, the optical plate 31 is installed on the movable post 23 and the crossbar. The diameter of the optical plate 31 pushes the movable post 23 downward. After the movable post 23 moves downward, the reset mechanism 29 is compressed and deformed. The deformed reset mechanism 29 generates a downward thrust. The movable post 23 moves upward and completes the compression and limiting of the optical plate 31 through the crossbar. Then the movable seat 22 is released, and the positioning post 24 returns to one end of the support frame 19 through the tension of the tension mechanism 25. The extrusion column 28, driven by the movable seat 22, enters the interior of the support frame 19. One end of the extrusion column 28 contacts and presses against the optical plate 31 for further positioning and fixation. When it is necessary to observe the optical plate 31, the fixing frame 11 is moved upward, and the ring seat 10 moves upward inside the slide groove 32 via the slider 33. After the fixing frame 11 moves upward, one end of the fixing insert 18 separates from the rubber ring 20. The movable seat 22 drives the support frame 19 to rotate via the positioning column 24, adjusting the focal point of the optical plate 31. After adjustment, the fixing frame 11 is released. After the fixed frame 11 is returned to its position, the fixed insert 18 contacts the rubber ring 20 to limit the support frame 19. When it is necessary to adjust the height of the fixed frame 11, the threaded tube 8 drives the threaded column 9 to move towards the support tube 2. Under the movement of the threaded column 9, the threaded column 9 pushes the fixed plate 5 and the fixed column 3 to rise through the threaded tube 8. The fixed column 3 moves in the support tube 2 through the connecting column. After the tilt angle of the threaded column 9 is adjusted, the rotating shaft 6 is fixed by the fastening bolt 7, so that the height of the fixed column 3 can be finely adjusted through the threaded column 9.
