When the level bubble 120 is balanced, the air bubble in the level bubble 120 is located at the middle position, the infrared signals received by the two photosensitive diodes have the same intensity, and the currents output by the two photosensitive diodes are the same; when the level bubble is inclined (i.e., unbalanced), the position of the bubble in the level bubble 120 is shifted, the infrared signal intensities received by the two photodiodes are unequal, the currents output by the two photodiodes are different, and the angle deviation between the main optical axis of the movement and the horizontal plane can be determined according to the difference of the currents. The first sensing unit 100 is configured such that the core primary optical axis coincides with the horizontal plane when the vial 120 is balanced. Because the first sensing unit 100 is fixedly connected with the movement, the main optical axis of the movement can be coincided with the horizontal plane only by adjusting the posture of the movement through the first leveling mechanism 300 according to the sensing result of the first sensing unit 100 to balance the level bubble 120, and the reference line formed by the sweep level on the target object is a vertical line (i.e. a plumb line).

Specifically, the level bubble, the light emitting element, and the two light sensing elements of the second sensing unit 200 may be disposed at 90 ° with respect to the first sensing unit 100.

In some embodiments, the second sensing unit 200 may be a capacitive or inductive level meter, as long as it is configured such that when it is horizontal, the main optical axis of the movement is perpendicular to the horizontal plane.
The first flattening mechanism 300 includes: a leveling motor 310 fixedly attached to said deck; the screw rod 320 is fixedly connected with the leveling motor 310, and the leveling motor 310 drives the screw rod 320 to rotate; the screw rod sleeve 330 is fixedly connected with the shell and is in threaded connection with the screw rod 320; when the screw rod 320 rotates, the screw rod 320 makes a linear motion relative to the screw rod sleeve 330, so as to drive the movement to deflect relative to the shell and adjust the angle between the main optical axis of the movement and the horizontal plane. The first leveling mechanism 300 is configured to adjust an angle between a main optical axis of the movement and the horizontal plane according to a sensing result of the first sensing unit 100, so that the main optical axis of the movement coincides with the horizontal plane. The second leveling mechanism 400 also includes a leveling motor, a lead screw, and a lead screw sleeve, and the setting of the second leveling mechanism is substantially the same as that of the first leveling mechanism 300, and is not repeated here, but the difference is that the second leveling mechanism is configured to adjust the angle between the main optical axis of the movement and the horizontal plane according to the sensing result of the second sensing unit 200, so that the main optical axis of the movement is perpendicular to the horizontal plane.
