[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A three-point level adjustment mechanism includes threaded holes 7 arranged at equal angles on a lower panel 1, and an adjustment screw 3 is threadedly connected to the threaded holes 7; and also includes: an upper panel 2, which is superimposed on the lower panel 1;

[0025] Conical holes are provided below the lower panel 1 and on the upper panel 2;

[0026] The center ball 5 is squeezed and engaged in the conical holes on the lower panel 1 and the upper panel 2. Through the setting of the center ball 5, the center holes of the lower panel 1 and the upper panel 2 are in contact with the center ball 5 to form a rotation center, and the horizontal positioning of the center is realized.

[0027] The above structure solves the problem that the center holes of the lower panel 1 and the upper panel 2 contact with the center ball 5 to form a rotation center and realizes the horizontal positioning of the center. Through the setting of the center ball 5, the angle between the lower panel 1 and the upper panel 2 can be adjusted, so that the lower panel 1 and the upper panel 2 remain horizontal. There is no need to select an adjustment screw 3 of a suitable length according to the thickness of the equipment, which facilitates its adjustment.

[0028] The butterfly spring piece group 6 is arranged at an equal angle on the lower panel 1. The butterfly spring piece group 6 is located above the threaded hole 7. The butterfly spring piece group 6 provides tension that spreads outward and forms a balance with the screw locking force. The outer diameter of the butterfly spring piece group 6 is 34 mm, and the butterfly spring piece group 6 passes through the outside of the adjusting screw 3. The top of the butterfly spring piece group 6 can contact the bottom of the upper panel 2.

[0029] The setting of the above-mentioned butterfly spring group 6 can provide outward-spreading tension, which forms a balance with the locking force of the adjusting screw 3. At the same time, the setting of the butterfly spring group 6 prevents the lower panel 1 and the upper panel 2 from contacting each other, thereby reducing the force between the lower panel 1 and the upper panel 2. The butterfly spring group 6 between the upper panel 2 and the lower panel 1 provides upward tension. The highest and lowest points are measured by measuring with a meter or other means. The height and low adjustment of the current orientation are controlled by adjusting the tightening and loosening of the corresponding orientation adjusting screw 3, thereby finally achieving a horizontal posture of the upper panel 2.

[0030] The adjusting screw 3 has a fine thread, and there are three adjusting screws 3, which correspond one to one with the threaded holes 7. The horizontal posture of the upper panel 2 can be adjusted by rotating the adjusting screw 3. Countersunk holes 4 are opened at equal angles inside the upper panel 2, and there are three countersunk holes 4, which are aligned with the threaded holes 7, and the adjusting screw 3 is inserted into the inside of the countersunk holes 4.

[0031] The arrangement of the above structure can change the distance between the lower panel 1 and the upper panel 2. When the upper panel 2 is not in a horizontal position, the screw head of the adjusting screw 3 is facing upward, and the adjusting screw 3 is extended and retracted by rotating the adjusting screw 3. When the lower panel 1, the upper panel 2 and the center ball 5 are installed, the three are squeezed and positioned. During adjustment, the upper panel 2 will slide relative to the fixed lower panel 1 and the center ball 5, and the center position will be automatically aligned through the center ball 5. The angular position is oriented by the three adjusting screws 3 until the upper panel 2 remains horizontal.

[0032] Working principle: When using the three-point level adjustment mechanism, first observe the angles of the lower panel 1 and the upper panel 2. When the lower panel 1 and the upper panel 2 are not in a horizontal position, turn the corresponding adjusting screw 3 by hand. During the rotation of the adjusting screw 3, the upper panel 2 can be pulled and pushed until the upper panel 2 maintains a horizontal position. During the process of pushing and pulling the upper panel 2, the center holes of the lower panel 1 and the upper panel 2 contact the center ball 5 to form a rotation center, and realize the horizontal positioning of the center.
