By controlling the angle and position of the scanning mirror, the laser beam can draw the desired line on the projection plane.

[0023] The level bubble 2 consists of a round transparent or translucent disk filled with liquid; there is a thin line or mark in the center of the level bubble 2 to indicate the horizontal position. When the level bubble 2 is placed on a horizontal surface, the bubbles in the liquid will automatically move to the center position and align with the mark, indicating that the surface is horizontal.

[0024] When in use, hold the two handles 6 with both hands and place the verification device on the ground. At this time, the leveling legs 4 are unlocked. Then, in the process of placing the verification device, the verification device is close to a horizontal state by observing the level bubble 2. After the leveling legs 4 touch the ground, the leveling legs 4 are freely raised and lowered on the leveling base, so that the bottom end of the leveling legs 4 automatically adapts to the ground conditions and can maintain the horizontal state of the verification device.

[0025] After the verification device is placed on the ground, the two handles 6 are controlled to move horizontally, and the handles 6 lock the leveling legs 4 in the height direction through the locking assembly 5, thereby stably supporting the verification device, and in the process of horizontally moving the handles 6, the position of the verification device in all directions in the height direction is maintained, so that the leveling legs 4 of the verification device can be kept in a horizontal state when stably supported.

[0026] Therefore, after applying the above embodiment, when placing the verification device on the ground, the unlocked leveling legs 4 can be freely raised and lowered on the leveling base to automatically adapt to different ground conditions. At the same time, by moving the handle 6 horizontally, the locking assembly 5 is controlled to lock the leveling legs 4, so that the leveling legs 4 can stably support the verification device on the ground.
