[0045] The inside of the protective cloth 65 is embedded with metal films 22 arranged at equal distances.

[0046] In the present application, after the sand table main body 2 is used, the user can turn the sand table main body 2 by 180 degrees, rotate the wire pipe, make the display area of the sand table main body 2 face downward, and magnetically connect the magnetic plate 19 and the frame-shaped box 7 to ensure stability. Then, the driving fixed plate 12 is driven to move to the last side. In the movement process, the protective cloth 65 in the storage box 61 is pulled and shielded to the top of the sand table main body 2. The base 1 is matched with the sand table main body 2 to cover and prevent dust. Since the protective cloth 65 is pulled to the right position, the corresponding metal film 22 will be magnetically connected with the corresponding magnet 16, so that the protective cloth 65 is in a taut state. Therefore, the space between the protective cloth 65 and the sand table main body 2 forms a buffer area, which can reduce the phenomenon that the accidental knocking and falling of external articles cause damage to the sand table main body 2, and further increase the protection effect. In the later use, the driving fixed plate 12 can be reset, and then the torsional spring 64 on the fixed shaft 62 will drive the sleeve pipe 63 and the protective cloth 65 to reset.
