Compared with the existing technology, the beneficial effects of this utility model are:

1. When it is necessary to adjust the level of the theodolite body, first turn the rotating ring. Since the rotating ring and the screw are threaded, when the rotating ring rotates, it will drive the screw to slide inside the sleeve. At the same time, the screw and the connecting frame are rotationally connected. , so when one of the screws moves, it will drive the connecting frame to tilt, thereby achieving the adjustment effect. It can be used on complex and uneven terrain. Through the above mechanism, it is more convenient to adjust the level of the theodolite body in complex environments.

2. When it is necessary to protect the lens of the theodolite body, first pull the telescopic rod. At this time, the telescopic rod and the spring shrink. Then the telescopic rod detaches from two of the slots. At this time, the slider slides on the outside of the slide rod and downwards. Then the slider drives the inclined rod to move. When it moves to the designated position, the telescopic rod enters the other two slots. At this time, the protective cover is flush with the lens of the theodolite body, thereby achieving a protective effect and making it This prevents the lenses from getting scratched when left idle outdoors.
