The fine-tuning lifting cylinder 16 slides inside the fine-tuning support cylinder 15, thereby limiting the position of the fine-tuning lifting cylinder 16, thereby increasing the sliding stability of the fine-tuning lifting cylinder 16.

[0023] In this embodiment, specifically: the coarse adjustment component 2 includes a coarse adjustment support cylinder 20, a rotating shaft 21, a gear 22, a coarse adjustment lifting cylinder 23, a slide groove 24, a toothed plate 25 and a coarse adjustment reduction motor 26.

The output end of the horizontal sensor 27 is electrically connected to the input end of the leveling controller 28.

[0028] In this embodiment, specifically: limiting grooves 33 are provided on both sides of the fine-tuning lifting cylinder 16, and the inner walls of the two limiting grooves 33 are slidably connected to the outer walls of the limiting block 31. The limiting grooves 33 on the fine-tuning lifting cylinder 16 slide along the outer wall of the limiting block 31, thereby limiting the fine-tuning lifting cylinder 16.

[0030] The working principle or structural principle is that when in use, the coarse adjustment reduction motor 26 is started through the leveling controller 28 to drive the rotating shaft 21 to rotate, thereby driving the gear 22 to rotate, and the gear 22 is meshed and connected with the toothed plate 25 on the inner wall of the coarse adjustment lifting cylinder 23, so that the rotation of the gear 22 drives the coarse adjustment lifting cylinder 23 to move up and down inside the coarse adjustment support cylinder 20, thereby preliminarily adjusting the height and levelness of the total station body 30 on the triangular base 11, and on uneven ground, the three coarse adjustment lifting cylinders 23 are adjusted separately, so as to preliminarily level the total station body 30. After the preliminary leveling, the level sensor 27 on the triangular base 11 is used to monitor in real time. The horizontal state of the triangular base 11 is monitored and the monitoring data is transmitted to the leveling controller 28. Then the leveling controller 28 controls the three fine-tuning reduction motors 17 to drive the screw 18 to rotate according to the received data, thereby driving the fine-tuning lifting cylinder 16 to perform fine-tuning lifting and lowering movements inside the fine-tuning support cylinder 15, and then accurately leveling the triangular base 11 and the total station body 30. After the total station body 30 reaches the horizontal state, the fine-tuning reduction motor 17 and the coarse-tuning reduction motor 26 stop working. At this time, the total station body 30 completes rapid leveling, and the operator can rotate the total station body 30 through the rotating seat 29 to adjust the angle to meet the needs of the measurement work.
