[0023] Please refer to Figures 1-2 , four frame columns 31 are fixedly installed on the top of the sand table frame 3, and a protection structure 4 is fixedly installed on the outer surface of the four frame columns 31. The four protection structures 4 include two slide rails 41, and the two slide rails 41 are fixedly connected to the frame columns 31. A sliding block 42 is slidably installed inside the two slide rails 41, and a folding cloth 43 is fixedly installed at one end of the two sliding blocks 42. One end of the folding cloth 43 is fixedly connected to the slide rail 41.

[0024] When the holographic projection component 33 is not in use, by sliding the sliding block 42, the folding cloth 43 is pulled up, so that the folding cloth 43 can block the four sides of the holographic projection component 33, thereby avoiding damage to the holographic projection component 33 caused by external factors when the holographic projection component 33 is not in use.

[0025] Please refer to Figures 1-2, at the top of the four support columns 31, a top plate 32 is fixedly installed, and at the bottom of the top plate 32, a holographic projection component 33 is fixedly installed.

[0026] Holographic projection can be carried out through the holographic projection component 33 for all-round display.

[0027] Working principle: When a multimedia display sand table is in use, first pull down the four folding cloths 43 to expose the holographic projection component 33, and at this time, display can be carried out. When the device needs to be moved, by starting the hydraulic cylinder 22, its telescopic rod drives the support plate 27 to move downward. Since the four fixed rings 28 are fixedly connected to the four sliding sleeves 24, and since the support columns 29 are slidably connected to the base 1, the four support columns 29 can support the support plate 27. When the sliding sleeve 24 drives the universal wheel 25 to move downward, the storage frame 21 can drive the base 1 and other structures above to be lifted. Thus, the device can be moved through the four universal wheels 25. When the holographic projection component 33 is not in use, by sliding the sliding block 42, the folding cloth 43 is pulled up. Thus, the folding cloth 43 can block the four sides of the holographic projection component 33, thereby avoiding damage to the holographic projection component 33 caused by external factors when the holographic projection component 33 is not in use.
