[0019] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Please refer to Figure 6 an existing optical adjustment frame: including an adjustment frame 11, a fixed frame 12, an adjustment plate 13 and a spring 14. The adjustment frame 11 and the fixed frame 12 are connected by the spring 14. After the spot is adjusted, the spring force of the spring 14 is used to fix the adjustment frame 11 and the fixed frame 12. However, the locking method has uncertainty, and the adjustment frame 11 will drive the optical lens to shake due to shaking, thereby causing the spot to shake.

[0021] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0022] An optical adjustment frame, comprising an adjustment frame fixed seat 1, a fixed rotation assembly 2, an adjustment plate 3, an optical mirror 4 and a fixed shaft 5.

[0023] One side surface of the adjustment frame fixed seat 1 is provided with the fixed rotation assembly 2.

[0024] For the convenience of understanding the fixed rotation assembly 2 in this embodiment, the fixed rotation assembly 2 will be further described.

[0025] The fixed rotation assembly 2 is used to fix the adjustment plate 3 and realize the rotation of the adjustment plate 3 under certain conditions.

[0026] In one embodiment, the fixed rotation assembly 2 includes the following parts: two fixed grooves 201 and two screws 203. By adjusting the position of the screw 203 in the inner cavity of the fixed groove 201, the adjustment plate 3 is fixed, and then the optical mirror 4 is fixed, preventing the optical mirror 4 from being interfered by environmental factors, causing shaking and resulting in optical path deviation. At the same time, the position of the screw 203 in the inner cavity of the fixed groove 201 can also be adjusted, so that the adjustment plate 3 deflects slightly by relying on the pin shaft 202, and then the optical path deflects.

[0027] In another embodiment, the fixed rotation assembly 2 includes the following parts: two fixed grooves 201 and two screws 203, and the fixed grooves 201 are arc-shaped. By adjusting the position of the screw 203 in the inner cavity of the fixed groove 201, the screw 203 loses the fixation of the adjustment plate 3, and the adjustment plate 3 rotates by relying on the pin shaft 202. After that, the screw 203 fixes the adjustment plate 3 after a small rotation, so as to achieve the fixation of the adjustment plate 3 after a small rotation, and further make the fixation effect of the adjustment plate 3 more comprehensive, and further avoid the offset of the light spot.

[0028] One side surface of the adjustment frame fixed seat 1 is provided with the fixed rotation assembly 2. The fixed rotation assembly 2 is rotationally connected with the adjustment plate 3. The inner wall of the adjustment plate 3 is fixedly installed with the optical mirror 4. The lower end of the adjustment frame fixed seat 1 is movably sleeved with the fixed shaft 5;

[0029] The fixed rotation assembly 2 includes a fixed groove 201, a pin shaft 202 and a screw 203. The fixed groove 201 is opened on one side surface of the adjustment frame fixed seat 1. One side of the pin shaft 202 is rotationally connected with the adjustment frame fixed seat 1, and one side of the pin shaft 202 is rotationally connected with the adjustment plate 3. The screw 203 penetrates through the fixed groove 201 and is threadedly connected with one side surface of the adjustment plate 3.

[0030] The adjusting plate 3 is fixed by the fixed rotation assembly 2 on one side of the adjustment frame fixing seat 1, so as to fix the adjusting plate 3 and the optical mirror 4, prevent the optical mirror 4 from being interfered by external environmental factors during use, cause the light spot to shift, and thus ensure the stability of the device. At the same time, the adjusting screw 203 can also be adjusted so that the adjusting screw 203 is adjusted in the fixing groove 201, so that the adjusting plate 3 and the optical mirror 4 rotate at a small angle through the pin shaft 202, and then fix the rotated adjusting plate 3 and the optical mirror 4 by adjusting the screw 203, thereby achieving the fixation of the adjusting plate 3 and the optical mirror 4, preventing the device from being interfered by environmental factors, causing shaking and causing the light path to shift and the light spot to shift.

[0031] Specifically, the nut of the screw 203 is countersunk in the inner cavity of the fixing groove 201.

[0032] The position of the adjusting screw 203 in the inner cavity of the fixing groove 201 can be adjusted, so that the fixing plate can rotate slightly depending on the 202 pin shaft.

[0033] Specifically, the adjustment frame fixing seat 1 is L-shaped, and a pin hole for fixing is opened at the lower end of the adjustment frame fixing seat 1, and a fixing shaft 5 is installed inside the pin hole.

[0034] The adjustment frame fixing seat 1 can be fixed through the pin hole. At the same time, the pin hole of the adjustment frame fixing seat 1 and the fixing shaft 5 can be fixed and moved back and forth. The adjustment frame fixing seat 1 can also be rotated through a single fixing shaft 5, thereby increasing the stability and application range of the adjustment frame fixing seat 1.

[0035] Specifically, the fixing groove 201 is a straight groove type and is mutually defined with the screw 203.

[0036] By adjusting the position of the adjusting screw 203 in the inner cavity of the fixing groove 201, the adjusting plate 3 and the optical mirror 4 can rotate slightly through the pin shaft 202, and thus the light spot can be deflected.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it.
