A sliding groove 13 located above the support block 12 is provided on the bottom left side of the mounting block 5. A slider 14 extending to the bottom of the mounting block 5 and movably connected to the top of the support block 12 is movably installed inside the sliding groove 13. A rotating block is fixedly installed on the top of the support block 12. The slider 14 is movably connected to the top of the support block 12 through the rotating block.

[0022] A U-shaped plate 15 is fixedly installed on the bottom right side of the column 2. A transmission assembly 16 is movably installed on the right side of the inner wall of the U-shaped plate 15, with one end extending into the rectangular groove 9 and fixedly connected to the outside of the threaded rod 10. The transmission assembly 16 includes a transmission shaft 161. A second bearing is fixedly installed on the right side of the inner wall of the U-shaped plate 15. The transmission shaft 161 is rotatably connected to the right side of the inner wall of the U-shaped plate 15 through the second bearing. The bottom right side of the inner wall of the rectangular groove 9 is connected to a mounting hole opened on the column 2 and adapted to the transmission shaft 161. A drive bevel gear 162 is fixedly installed on the left side of the transmission shaft 161. A driven bevel gear 163 located below the moving block 11 and meshing with the drive bevel gear 162 is fixedly installed on the outside of the threaded rod 10.

[0023] A rotating assembly 17 is fixedly installed on the outer side of the transmission assembly 16. One end of the rotating assembly 17 is movably connected to the inner bottom wall of the U-shaped plate 15, and the other end extends to the top of the U-shaped plate 15. The rotating assembly 17 includes a worm gear 171. The worm gear 171, located behind the transmission shaft 161 and extending to the top of the U-shaped plate 15, is movably installed on the inner bottom wall of the U-shaped plate 15. A third bearing is fixedly installed on the inner bottom wall of the U-shaped plate 15. The worm gear 171 is rotatably connected to the inner bottom wall of the U-shaped plate 15 through the third bearing. A worm wheel 172, located inside the U-shaped plate 15 and meshing with the worm gear 171, is fixedly installed on the outer side of the transmission shaft 161. A hand crank turntable 173 is fixedly installed on the top of the worm gear 171.

[0024] Working principle: When it is necessary to adjust the pitch angle of the laser 6 output light source, the worm gear 171 can be rotated by turning the hand crank 173, which in turn drives the transmission shaft 161 and the drive bevel gear 162 to rotate through the worm wheel 172. The driven bevel gear 163 then drives the threaded rod 10 to rotate. During the rotation of the threaded rod 10, the moving block 11 will move up or down, which in turn drives the mounting block 5 to rotate clockwise or counterclockwise around the mounting shaft 4 through the support block 12, the slider 14, and the slide groove 13. At the same time, the rotation angle of the mounting block 5 can be precisely controlled by the angle scale on the pointer 7 and the protractor 8. Finally, the pitch angle of the laser 6 output light source can be adjusted. Therefore, the pitch angle of the laser 6 output light source can be adjusted according to the actual situation, thereby improving applicability and facilitating the user.

[0025] In summary, this fiber optic assembly angle adjustment seat rotates the worm gear 171 by turning the hand crank 173, which in turn drives the transmission shaft 161 and the drive bevel gear 162 to rotate via the worm wheel 172. The driven bevel gear 163 then drives the threaded rod 10 to rotate. During rotation, the threaded rod 10 moves the moving block 11 up or down, which in turn drives the mounting block 5 to rotate clockwise or counterclockwise around the mounting shaft 4 via the support block 12, slider 14, and slide groove 13. Simultaneously, the rotation angle of the mounting block 5 can be precisely controlled via the pointer 7 and the angle scale on the protractor 8, ultimately adjusting the pitch angle of the laser 6's output light source. Therefore, during use, the pitch angle of the laser 6's output light source can be adjusted according to actual conditions, improving applicability and convenience for users. This solves the problem that existing semiconductor lasers often have difficulty adjusting the pitch angle of their output light source during actual use, thus hindering their operation.
