[0025] Among them, the guide rail 5 is fixed between the outer frame 10 and the support rod 11 through a fixing plate 14. The fixing plate 14 is of an L - shaped structure, and both sides of the fixing plate 14 fix between the guide rail 5 and the outer frame 10 and between the guide rail 5 and the support rod 11.

[0026] The feed screw 6 is located outside the guide rail 5, and a bearing is arranged between the feed screw 6 and the feed screw fixing plate 15. At the same time, in order to facilitate the rotation of the first handwheel 16, a handle can be arranged on the first handwheel 16. During use, rotate the first handwheel 16, so that the feed screw 6 rotates in the feed screw fixing plate 15 through the bearing, and the slider 7 sleeved on the feed screw 6 slides back and forth along the feed screw 6.

[0027] The up-and-down adjustment assembly 4 includes a worm 17, a turbine 18, a first worm fixing plate 19, a second worm fixing plate 20, a first optical axis 21, a second optical axis 22, and a lead screw 23; the first worm fixing plate 19 and the second worm fixing plate 20 are fixed on the outside of the lead screw fixing plate 9, and the first worm fixing plate 19 is fixed to the lower end of the slider 7; both ends of the worm 17 are rotatably arranged on the first worm fixing plate 19 and the second worm fixing plate 20, and a second handwheel 24 is arranged at one end of the worm 17 away from the second worm fixing plate 20; the upper end of the lead screw 23 is rotatably arranged on the lead screw fixing plate 9, and a turbine 18 is fixed on the lead screw 23; the first optical axis 21 and the second optical axis 22 are fixed on the lead screw fixing plate 9, and the first optical axis 21 and the second optical axis 22 are located on both sides of the lead screw 23; the turbine 18 and the worm 17 are meshed with each other.
