And when clamping the lens, due to different models of the lens, there are differences in the shape of the lens. However, the clamping and placement of the prior art are too fixed, resulting in only regular-shaped lenses can be clamped, resulting in poor applicability. Therefore, it is necessary to improve the prior art. Summary of the Utility Model

[0006] Preferably, the handwheel is in contact with the clamping frame, and a belt is sleeved on the outside of the handwheel, and the belt can drive the two positive and negative screw rods to rotate simultaneously.

[0007] Preferably, one end of the first spring is fixedly connected to the clamping frame, and the other end of the first spring is fixedly connected to the threaded frame. The first spring can support the clamping frame through its elastic force.

[0008] Preferably, the angle adjustment mechanism includes a limiting wheel. A limiting wheel is fixedly connected to the outside of the connecting shaft at the right end of the clamping frame. A fixed plate is fixedly connected to the right end of the bracket. A limiting frame is slidably connected inside the fixed plate. A pull ring is fixedly connected to the lower end of the rod of the limiting frame. A second spring is arranged outside the rod of the limiting frame. The pull ring can drive the limiting frame to move.

[0009] Preferably, one end of the second spring is fixedly connected to the fixed plate, and the other end of the second spring is fixedly connected to the limiting frame. The second spring can drive the limiting frame to automatically reset through its elastic force.

[0010] Preferably, the limiting frame is clamped with the groove of the limiting wheel, and the pull ring contacts the fixed plate. The limiting frame can limit the use angle of the clamping frame through the limiting wheel.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By adding structures such as a bracket, a limiting wheel, and a clamping frame to the base in the present utility model, the flipping angle of the clamping frame can be limited by the limiting wheel during use.

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 4, the angle adjustment mechanism 4 includes a limit wheel 41. The limit wheel 41 is fixedly connected to the outside of the connecting shaft at the right end of the clamping frame 3. The right end of the bracket 2 is fixedly connected with a fixing plate 42. The inside of the fixing plate 42 is slidably connected with a limit frame 43. The lower end of the rod of the limit frame 43 is fixedly connected with a pull ring 45. A second spring 44 is arranged outside the rod of the limit frame 43. The pull ring 45 can drive the limit frame 43 to move. One end of the second spring 44 is fixedly connected with the fixing plate 42, and the other end of the second spring 44 is fixedly connected with the limit frame 43.
