[0022] Furthermore, LED splicing screens are fixed inside the upper mounting plate 102 and the lower mounting plate 103. The inner ends of the LED splicing screens are plugged into the plug-in slot 105. The two LED splicing screens are fixed in the middle by plugging. When splicing, each single board of the LED splicing screen is fixed in the plug-in slot 105 of the upper mounting plate 102 or the lower mounting plate 103. The upper and lower connection positions of the two splicing screens are on the upper mounting plate 102 and the lower mounting plate 103. The upper mounting plate 102 and the lower mounting plate 103 are used to limit the position of the splicing screen, and the middle connection position is limited and fixed.

[0023] Furthermore, a sliding bin 108 is provided on one side of the fixed frame 101, and a plug-in bin 109 is provided inside the sliding bin 108. The plug-in plate 207 slides inside the sliding bin 108 to achieve the effect of limiting the movement of the baffle 206. When the baffle 206 moves to the inside, it abuts against the outer end of the upper mounting plate 102 and the lower mounting plate 103 on the far left, which has a tightening effect on the internal structure of the fixed frame 101, strengthens the firmness of the connection between the left and right sides of different splicing screens, and avoids loosening after the splicing screens are connected.

[0025] Furthermore, a threaded rod 205 is fixedly connected from the middle of the outer side of the gear 204, the outer side of the threaded rod 205 is threadedly connected to the baffle 206 and the inner side of the plug-in board 207, the outer side of the baffle 206 is slidably connected to the inside of the sliding bin 108, the outer side of the plug-in board 207 is slidably connected to the inside of the plug-in bin 109, the inside of the baffle 206 abuts against the outer side of the upper mounting plate 102 and the lower mounting plate 103 on the far left, and the other end of the threaded rod 205 is rotatably connected to the inside of the plug-in bin 109, ensuring the correct positioning of the baffle 206 and the plug-in board 207. Often move, after the splicing screens inside the fixed frame 101 are installed, the double-headed motor 201 controls the operation of the two sets of transmission components, thereby controlling the movement of the baffle 206 on the outside of the threaded rod 205, and the baffle 206 moves from the left side to the middle, so that the inside of the baffle 206 abuts against the upper mounting plate 102 and the lower mounting plate 103 on the leftmost side, and the internal structure is pressurized. The splicing screens on the upper mounting plate 102 and the lower mounting plate 103 can improve the firmness of the connection under pressure, and avoid the loosening of the connection position when the position is transferred.

[0026] Furthermore, the main gear 203 and the slave gear 204 are both helical gears, which can ensure a normal power transmission effect. The main gear 203 and the slave gear 204 constitute a transmission assembly.
