[0026] As Figure 1 shown, embodiments of the present application provide a laser lens group detection adjusting mechanism, which comprises a lens group mechanism 1 and a detection mechanism 2 for detecting the lens group assembly mechanism.

[0027] As Figure 2 shown, the lens group mechanism 1 comprises a mounting plate 11 and a lens group assembly 12, the lens group assembly 12 is mounted on the mounting plate 11, the lens group assembly 12 comprises a negative focal length lens mechanism 121, a positive focal length lens mechanism 122 and a lens barrel 123, the negative focal length lens mechanism 121 is connected with one end of the lens barrel 123 through threads, and the positive focal length lens mechanism 122 is connected with the other end of the lens barrel 123 through threads.

[0029] Specifically, the negative focal length lens 102 is installed on the first step 002 of the first through hole 001 of the first mounting mirror seat 100, the first compression ring 101 is threadedly connected with the first through hole 001 of the first mounting mirror seat 100, and the negative focal length lens 102 is fixed. Then threadedly connect the first mounting mirror seat 100 with one end of the lens barrel 123. The structure and installation steps of the positive focal length lens mechanism 122 and the negative focal length lens mechanism 121 are the same. The positive focal length lens mechanism 122 is threadedly connected with the other end of the lens barrel 123. Then install the assembled lens group assembly 12 on the mounting plate 11. Finally, install the mounting plate 11 on the fixed platform 25 of the detection mechanism 2.

[0030] By rotating the first mounting mirror seat 100 or the second mounting mirror seat 103 to adjust the distance between the negative focal length lens 102 and the positive focal length lens 105, so that the light spot reaches the near focus state, then the first linear module 22 and the second linear module 23 of the detection mechanism 2 drive the laser analyzer 24 to move to the light emitting position, and capture the light spot data. Using the captured light spot information, fine-tune the instrument position to make the light spot reach the center of the field of view, and then fine-tune the first mounting mirror seat 100 or the second mounting mirror seat 103 to make the light spot reach the finest state.
