The mounting portion 7 is fixed on the supporting wall 6, and the mounting portion 7 is provided with at least one mounting position 70. The wireless inductive servo stepping mechanism 8 is accommodated in the mounting position 70. A plurality of LED display units 1001 are mounted on the corresponding wireless inductive servo stepping mechanism 8 to be spliced ​​into an LED display screen 1000. The handheld wireless inductive calibration device 9 measures the flatness between adjacent LED display units 1001 and forms an adjustment data signal to be sent to the wireless inductive servo stepping mechanism 8, and then the wireless inductive servo stepping mechanism 8 performs telescopic movement relative to the mounting position 70 to drive the corresponding LED display unit 1001 to move.

[0029] In this embodiment, the mounting portion 7 is fixed to the supporting wall 6 by means of threaded connection or other fixing methods. There are multiple mounting positions 70 , and one mounting position 70 is used to mount one wireless inductive servo stepping mechanism 8 .

[0030] In this embodiment, the adjustment data signal includes a movement stroke L of the wireless inductive servo stepping mechanism 8 extending and retracting relative to the installation position 70 .

[0031] In this embodiment, through the cooperation between the wireless inductive servo stepping mechanism 8 and the handheld wireless inductive calibration device 9, it is possible to automatically and accurately adjust the flatness of the LED display screen 1000. Compared with the traditional adjustment method that relies on processing accuracy, assembly accuracy and on-site manual adjustment accuracy, the adjustment method of the present invention has the characteristics of automation, intelligence, high efficiency and low labor cost, which solves the problems of fine-tuning of the flatness of LED small-pitch display screens, difficult maintenance and low adjustment efficiency.

[0032] For further information, please refer to Figure 4-Figure 6 The wireless inductive servo stepping mechanism 8 includes a first main body 1, a signal processing device 2 and a driving unit 3 installed in the first main body 1, and a top rod 4 driven by the driving unit 3. The LED display unit 1001 is hooked on the top of the top rod 4. When the signal processing device 2 receives a control motion command, the driving unit 3 starts and drives the top rod 4 to extend and retract relative to the first main body 1, so that the LED display unit performs a telescopic motion together.

[0033] Furthermore, the driving part 3 is transmission-connected with the push rod 4 , and the driving part 3 can rotate relative to the first body 1 .

[0034] Furthermore, when the driving part 3 rotates in the first direction, the push rod 4 extends outward.

[0035] Furthermore, when the driving part 3 rotates in the second direction, the push rod 4 contracts inwardly, and the first direction and the second direction are opposite.

[0036] In this embodiment, the first direction is clockwise and the second direction is counterclockwise; of course, in other embodiments, it can also be arranged that when the driving part 3 rotates counterclockwise, the push rod 4 extends outward; when the driving part 3 rotates clockwise, the push rod 4 contracts inward, which are all within the protection scope of the present invention.

[0037] In this embodiment, the control motion command includes the extension and retraction distance of the push rod 4, and the control motion command comes from the handheld wireless sensing calibration device 9.

[0048] In this embodiment, the aperture of the receiving groove 12 is slightly larger than the accommodating cavity 10 , and the cover plate 5 is just flush with the depth of the receiving groove 12 when installed in the receiving groove 12 .

[0049] In this embodiment, the push rod 4 passes through the cover plate 5 , so that the push rod 4 and the cover plate 5 do not affect each other, and the cover plate 5 does not limit the telescopic movement of the push rod 4 .
