The working principle of the module fine adjustment mechanism is as follows:

after the electronic device 70 is fixed to the wall 80 by the module fine adjustment mechanism, if the electronic device 70 is too close to the wall 80, the rotary table 10 may be rotated in one direction to allow the first threaded shaft 20 to be unscrewed from the left-handed threaded groove 11, at this time, the second threaded shaft 30 is also simultaneously unscrewed from the right-handed threaded groove 12, the distance between the electronic device 70 and the wall 80 will be increased, and if the electronic device 70 is too far from the wall 80, the rotary table 10 may be rotated in the opposite direction to allow the first threaded shaft 20 to be rotated into the left-handed threaded groove 11, and at the same time, the second threaded shaft 30 is also rotated into the right-handed threaded groove 12, and the distance between the electronic device 70 and the wall 80 will be decreased.

When the outer surface of the electronic device 70 is viewed, if a certain corner of the outer side surface of the display unit 72 is too low relative to the whole plane of the display unit 72, the jacking screw 210 may be loosened for a certain distance, then the socket screw 220 may be screwed continuously, a certain gap may be jacked between the electronic device 70 and the connecting block 50 to raise the height of the corner of the electronic device 70, the position of the connecting block 50 is not fixed, and then the jacking screw 210 may be screwed tightly; if a corner of the display unit 72 is too high relative to the entire plane of the display unit 72, the other three corners need to be raised as before.

The module fine adjustment mechanism can be operated by a single person with one hand without excessive tools, and the operation method is simple and efficient without great effort.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
