[0021] The electric drive mechanism includes a rotary drive motor 9. On one side of the rotary drive motor 9, there is a second roller disc 22. A second O-ring 23 is arranged on the second roller disc 22. On one side of the rotary drive motor 9, there is a battery 15 for supplying power to the rotary drive motor 9 and the lifting drive motor 18. On one side of the battery 15, there is a main control board 11. On the outer side wall of the base 3, there are a button rubber 12 and a dust plug 13 corresponding to the main control board 11. At the end of the output shaft of the rotary drive motor 9, there is a second clamping part 26, and in the second roller disc 22, there is a second clamping groove 27 corresponding to the second clamping part 26.

[0022] The lower end surface of the sleeve 21 is provided with internal threads.

[0023] The outer side of the upper end of the foot 4 is provided with an external thread corresponding to the internal thread, and a limiting groove 37 is provided on the upper end surface of the foot 4.

[0024] The output shaft of the lifting drive motor 18 has a shape corresponding to the limiting groove 37.

[0025] The connecting member 1 includes a threaded section 28 connected to the sleeve 21. The upper end of the threaded section 28 is provided with a socket section 29 for sleeving the turntable 2.

[0027] The set 31 includes a pressure plate 35 for being connected to the turntable 2 by screws. A threaded sleeve 34 for installing a level is provided on the pressure plate 35.

[0028] Working principle of the present application: The present application includes two moving parts. One is the angle adjustment of the base 3, and the other is the adjustment of the height and levelness of the feet 4. There are two ways to adjust the angle of the base 3, manual and electric. The base 3 is used to install a level, and the level emits a laser for positioning. When using the present application, the receiver can be placed at the required height first, and the height and angle of the level are adjusted through the present application. The receiver emits a signal to the level at the positioning point. After receiving this signal, the level controls the rotation drive motor 9 and the lifting drive motor 18 through the main control board 11 to position the laser line at the position where the receiver is located. When adjusting manually, the operator holds the knob 5 and rotates it. When the knob 5 rotates, the connecting rod 6 drives the first roller disc 7 to rotate through the cooperation of the first clamping portion 24 and the first card slot 25, and drives the turntable 2 to rotate through the first roller disc 7, realizing the angle adjustment of the turntable 2. The angle of the turntable 2 can also be adjusted by an electric drive mechanism, which is powered by the battery 15. The battery 15 is provided with a battery cover 14, and the rotation drive motor 9 and the lifting drive motor 18 are controlled through the main control board 11. The rotation drive motor 9 is provided with a motor cover 10. When the rotation drive motor 9 works, the motor output shaft drives the second roller disc 22 to rotate through the cooperation of the second clamping portion 26 and the second card slot 27, and drives the turntable 2 to rotate through the second roller disc 22, realizing the angle adjustment of the turntable 2. The height of the feet 4 can be driven by the lifting drive motor 18. When the lifting drive motor 18 works, it drives the feet 4 to rotate through the cooperation of the output shaft and the limit groove 37. During the rotation of the feet 4, they move relative to the sleeve 21 through the cooperation of the external thread and the internal thread, and the feet slide relative to the output shaft of the lifting drive motor 18, realizing the position adjustment of the feet 4. A magnet 17 is provided at the upper end of the feet 4, which can cooperate with the Hall switch board 16 to detect the position of the feet 4, avoiding damage to the lifting drive motor 18 and poor reliability when the lifting drive motor 18 still works when the feet 4 have moved to the uppermost end. Further, the magnet 17 and the Hall switch board 16 can also be replaced by the cooperation of the trigger switch and the contact point.
