[0002] A lens is an optical element made of transparent material (such as glass, crystal, etc.). Convex lenses are thicker in the middle and thinner at the edges, and come in three types: biconvex, plano-convex, and concave-convex. Concave lenses are thinner in the middle and thicker at the edges, and come in three types: biconcave, plano-concave, and convex-concave. Lenses play an important role in fields such as astronomy, military, transportation, medicine, and art.

[0003] Existing optical lenses typically employ a fixed structure. First, the optical lens is installed in a support frame. Then, sealant is applied to the gap between the optical lens and the support frame to secure it. After securing, the support frame is installed onto the instrument that requires the optical lens. Finally, the instrument is turned on for operation.

[0004] In the existing technology, the optical lens is fixed in the support frame, which makes it inconvenient to disassemble the optical lens and inconvenient to adjust the optical lens in the experiment, thus greatly limiting the use of the optical lens. Utility Model Content

After clamping, the upper gear 24 drives the inner wall of the bearing 19 to rotate through the teeth 20, thereby driving the lens body 23 to rotate.

[0031] In one embodiment of the present invention, the side wall of the adjustment box 13 is provided with a side groove 14; two sets of side grooves 14 are provided. When working, the side grooves 14 are provided on the side wall of the adjustment box 13, so as to prevent the side wall of the adjustment box 13 from blocking the viewing angle when the lens body 23 is deflected.

[0034] Working Principle: To overcome the limitations of existing technologies where adjusting the optical lens during experiments is inconvenient and restricts its use, the lens body 23 is installed inside the bearing 19. Operators can adjust the lens body 23 using the adjusting gear 16 and teeth 20. A lower gear 17 is positioned next to the adjusting gear 16 and is fitted onto the first adjusting rod 18. When the operator rotates the first adjusting rod 18, the lower gear 17 drives the adjusting gear 16 to rotate. The bearing 19 is fixed to the adjusting gear 16 via the connecting column 31, thus driving the bearing 19 to deflect left and right. Then, the operator rotates the second adjusting rod 25, which drives the upper gear 24 to rotate. The upper gear 24 is a bevel gear that meshes with the teeth 20 on the side of the bearing 19. Rotation of the upper gear 24 causes the inner wall of the bearing 19 to rotate, which in turn rotates the lens body 23. The arrangement of the upper gear 24 and the lower gear 17 solves the problem of the lens body 23 being unable to be adjusted during experiments.

[0035] The lens body 23 is clamped by a clamping plate 22. The clamping plate 22 is fixed to the inner wall of the bearing 19 by a telescopic spring 21. During installation, the clamping plate 22 can extend and retract back and forth according to the setting of the telescopic spring 21 to accommodate different sizes of lens bodies 23. After installation, the lens body 23 can be rotated by the upper gear 24 for adjustment.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
