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

after the electronic device 70 is fixed on the wall 80 through the module fine adjustment mechanism, if the electronic device 70 is too close to the wall 80, the turntable 10 can be rotated in one direction to enable the first threaded shaft 20 to be screwed out of the left-handed threaded groove 11, at the same time, the second threaded shaft 30 is simultaneously in a screwed-out state from the right-handed threaded groove 12, the distance between the electronic device 70 and the wall 80 is increased, and if the electronic device 70 is too far from the wall 80, the turntable 10 can be rotated in the opposite direction to enable the first threaded shaft 20 to be rotated into the left-handed threaded groove 11, and meanwhile, the second threaded shaft 30 is also rotated into the right-handed threaded groove 12, so that the distance between the electronic device 70 and the wall 80 is reduced.

When the outer surface of the electronic device 70 is too low, if a certain corner of the outer side of the display unit 72 is too low relative to the whole plane of the display unit 72, the jacking screw 210 can be loosened for a certain distance, then the sleeve screw 220 is continuously screwed, a certain gap is jacked between the electronic device 70 and the connecting block 50 so as to raise the height of the corner of the electronic device 70, the position of the connecting block 50 is motionless, and then the jacking screw 210 is screwed; if a certain corner of the display unit 72 is too high with respect to the entire plane of the display unit 72, it is necessary to raise the other three corners in the previous manner.

The module fine adjustment mechanism can be operated by a single person with one hand, does not need too many tools, has simple and efficient operation method, and does not need to consume great effort.

Although the 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 scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
