In this embodiment, the triaxial moving mechanism 4 is for achieving movement in the X-axis direction, the Y-axis direction and the Z-axis direction, and can be achieved using a screw drive connection. The movement in the X-axis direction and the Z-axis direction is to realize the position shift of the sliding member 5 on the X-Z plane, and the movement in the Y-axis direction is to realize the distance adjustment between the sliding member 5 and the carrier member 1. When the lens 2 is fine-tuned, the slider 5 is then brought close to the carrier 1.
The bottom of slider 5 is provided with the rotating assembly, is connected with connecting frame 6 through the rotating assembly, is provided with adjustment mechanism on the connecting frame 6. Wherein the adjusting mechanism has an adsorption function, and the required angle adjustment and/or position adjustment is completed for the lens 2 under the condition of no shielding of laser rays.
