In order to ensure the accuracy of the measurement data of the auxiliary optical measurement equipment, the equipment needs to always ensure that its azimuth axis system is parallel to the geodetic coordinate system and the pitch axis system is perpendicular to the geodetic coordinate system. However, in actual use, since the flatness of the installation base cannot be determined, the auxiliary measurement equipment may change its angle due to the unevenness or tilt of the ground during installation, and it cannot be guaranteed that the installation base of the equipment remains parallel to the ground.

[0004] In the prior art, multiple tension springs and X-axis and Y-axis levels are added, which effectively solves the problem that the flatness of the installation base cannot be determined, and the angle of the auxiliary measuring equipment may change due to the unevenness or tilt of the ground during installation, and it is impossible to ensure that the installation base of the equipment remains parallel to the ground. However, although the overall adjustment response is relatively good, the single adjustment rate is too slow, and thus the leveling operation cannot be performed in a timely and effective manner.

The above-mentioned scheme solves the problem that although the overall adjustment response is relatively good, the single adjustment rate is too slow, thereby failing to perform the leveling operation in a timely and effective manner. It can be understood that the above-mentioned scheme can be used when an offset is required. During leveling, gravity will be utilized to make the sliding block 112 slide in the control box 109 according to the tilt angle. When sliding onto the sensing plate 110, the sensing plate 110 will control the telescopic column 103 to adjust the horizontal tilt angle of the leveling plate 104, thereby completing the leveling work. At the same time, the leveling ball 106 will effectively cooperate with the identification plate 107 to display the actual situation of the current tilt angle to the staff in real time, thereby actively and effectively solving the problem that although the overall adjustment response is relatively good, the adjustment rate is too slow, and thus the leveling operation cannot be performed in a timely and effective manner while retaining the original beneficial effects.
