[0009] Preferably, the lifting mechanism comprises threaded barrels fixed at equal angles to the top of the lower surface base, and a threaded rod is threadedly sleeved inside each threaded barrel.

[0010] Preferably, the bottom of the upper surface base is rotatably connected with a plurality of support shafts at equal angles, the bottom end of each support shaft is fixedly connected to the top end of each threaded rod, and a hand wheel is fixedly installed on the outer side of each support shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention, by setting a level bubble, facilitates the entire device to be in a roughly flat state, and facilitates turning on the laser and the centering device through an infrared remote controller, and facilitates the laser to accurately illuminate the target point through the coordination between the fixed platform, the lower slide plate, the slide plate, the upper slide plate, the top platform and the turntable;
