[0026] See also Figure 3-4 The specifications of the fixing block 16 and the fixing groove 11 match each other, and the fixing block 16 and the fixing groove 11 are slidably connected to each other, so that the display screen body 4 and the connecting plate 10 can be connected together. The baffle 14 and the groove 12 are slidably connected. There are two groups of springs 13, and the two groups of springs 13 are evenly distributed inside the groove 12. The baffle 14 can limit and fix the limit block 15. The surfaces of the bottom plate 1 and the connecting plate 10 are both provided with rounded corners. The surfaces are provided with rounded corners, and the rounded edges prevent users from being scratched by sharp corners.

[0027] Embodiment 2

[0028] See also Figure 2 A soft pad 5 is fixedly installed at the bottom end of the base plate 1, and an anti-skid pad 6 is fixedly installed at the end of the soft pad 5 away from the base plate 1, and an anti-skid strip 7 is fixedly installed at the end of the anti-skid pad 6 away from the soft pad 5, which improves the stability and anti-skid performance of the base plate 1. The anti-skid strip 7 is made of natural rubber, and the anti-skid strips 7 are evenly distributed at the bottom end of the anti-skid pad 6. The anti-skid effect of multiple anti-skid strips 7 is better. The soft pad 5 is fixedly connected to the base plate 1 by super glue, and the super glue connection is more firmly.

[0029] Working principle: when it is necessary to disassemble and assemble the LED display screen, the staff first presses the limit block 15 by hand and presses it into the groove 12 to release the limit on the limit block 15, and then pulls the display screen body 4 outward to remove it. During installation, because the limit block 15 is a triangle, it is only necessary to align the fixing block 16 with the fixing groove 11 and insert it. The inclined surface of the limit block 15 is squeezed and shrinks into the groove 12. When the limit block 15 completely passes through the fixing groove 11, the rebound force of the spring 13 pushes the limit block 15 out, and the baffle 14 fixes the limit block 15, and fixes the display screen body 4 and the connecting plate 10 together. The orientation of the display screen body 4 can be adjusted by rotating the bearing 2, and the angle of the display screen body 4 can be adjusted by moving the damping shaft 9 up and down. The rounded edges of the display screen body 4 prevent users from being scratched by sharp corners, thereby improving safety. The anti-slip strip 7 made of natural rubber at the bottom is not only more durable, but also enhances the stability and safety of the base plate 1.
