Background
In the long-time use process of the laser device, stable and reliable laser beam optical index output is obtained, which is an important technical requirement in the application design of laser engineering. As an important component of the laser, the long-term mechanical stability of the optical lens needs to be carefully considered, and the mechanical stability of the adjustable frame carrying the optical lens is particularly important. The common optical adjusting rack needs to have two functions, and the first is that the angle of the optical adjusting rack in the horizontal direction and the vertical direction is required to be adjustable. The other function is to lock the horizontal direction and the vertical direction respectively after the adjustment is finished so as to ensure the long-term reliability of the output parameters of the laser.
The conventional two-dimensional optical adjusting device utilizes the common cooperation of a thread pair and a spring to realize the fine adjustment function of adjusting the direction, and in the aspect of laser engineering, the adjusting frame cannot meet the requirement of long-time mechanical absolute stability of a laser.
