[0034] Specifically, the optical path lifting and adjusting device can be used as a transfer between two sets of assembled components, and a reflection unit 2 is used to receive the laser from one set of components, and then the received laser is reflected to another reflection unit 2, thereby realizing the vertical transmission of the laser, and then the other reflection unit 2 reflects the laser to another set of components, thereby realizing the splicing of the two sets of components; wherein, the position of the lifting body 21 on the guide column 11 is first adjusted, and then the height of the reflection unit 2 is fixed by using the first fixing mechanism; and then the rotating body 22 is rotated to adjust the horizontal direction of the optical lens to receive the laser and reflect the laser.

[0035] In some specific implementations, in order to facilitate the fixing of the lifting body 21, refer to Figure 2 and Figure 3 The lifting body 21 is provided with a sleeve portion 211, which is a hole or a C-shaped opening; the first fixing mechanism includes a first set screw 3, and the sleeve portion 211 is provided with a first set hole 212 in the radial direction. The first set screw 3 is threadedly connected with the first set hole 212, and the end of the first set screw 3 squeezes the outer wall of the guide column 11 to achieve relative fixation between the guide column 11 and the lifting body 21. In this way, by loosening or tightening the first set screw 3, the lifting body 21 can be lifted and fixed.

[0036] In some specific implementations, in order to facilitate the fixing of the rotating body 22, refer to Figure 3 The lifting body 21 is provided with a rotation hole 213, and the rotating body 22 is rotatably arranged in the rotation hole 213; the second fixing mechanism includes a second set screw 4, and the rotation hole 213 is provided with a second set hole 214 in the radial direction.

[0037] In some specific embodiments, reference Figure 2-5 The rotating body 22 is provided with a frame 23, and the optical lens is mounted on the frame 23; at least one of the two reflection units 2 is provided with a pitch adjustment mechanism 6, and the pitch adjustment mechanism 6 allows the frame 23 to deflect around a horizontal axis.

In other words, the spring 62 keeps the frame 23 in a tendency to approach the rotating body 22, and the line between the two fixed abutment blocks is equivalent to the horizontal axis.

Through the cooperation between the spheres 63 and the embedded holes, the frame 23 and the rotating body 22 are relatively fixed in the circumferential direction, so that the rotating body 22 can drive the frame 23 to rotate synchronously; by rotating the adjustment rod 64, the adjustment rod 64 is lifted and lowered relative to the rotating body 22, so as to adjust the deflection of the frame 23 around the horizontal axis.

[0040] In some specific embodiments, in order to facilitate the fixing of the optical lens on the frame 23, the optical lens is fixed to the frame 23 by a third fixing mechanism, the frame 23 is provided with a clamping hole 232 for placing the optical lens, the third fixing mechanism includes a third fixing screw 5, a third fixing hole 233 is radially opened in the clamping hole 232, the third fixing screw 5 is threadedly connected with the third fixing hole 233, and the end of the third fixing screw 5 squeezes the outer wall of the optical lens to fix the optical lens on the frame 23.
