The four universal wheels 112 are respectively fixedly connected to the four corners of the lower surface of the bottom plate 111. The universal wheels 112 have a self-locking structure.

[0028] During the specific setting, the lower surface of the support plate 120 is connected to the movable base 110, and a fixed plate 121 is provided on the lower surface of the support plate 120. The fixed plate 121 is fixedly connected to the upper surface of the base plate 111, and the bottom end of the positioning rod 130 is fixedly connected to the upper surface of the support plate 120. There are several positioning rods 130, and the bottom ends of several positioning rods 130 are all fixedly connected to the upper surface of the support plate 120. Several positioning rods 130 are evenly arranged.

[0029] In the present application, two elastic members 140 are provided, and the bottom ends of the two elastic members 140 are respectively rotatably connected to the two ends of the support plate 120. The bottom ends of the two elastic members 140 are each provided with a rotating shaft 141, and the two rotating shafts 141 are respectively rotatably connected to the two ends of the support plate 120. The limiting plate 150 is fixedly connected to the top ends of the two elastic members 140, and the two elastic members 140 are both springs.

[0030] See also Figure 1-5 A fixed block 210 is provided on the back of the display screen 200. The fixed block 210 is slidably mounted on the rod body of the positioning rod 130.
