Problems solved by technology

[0003] Usually, due to the large size of the whiteboard, it is relatively difficult to carry and carry it

If the whiteboard is small in size, although it is more convenient to carry and carry, but the usable area is small when used, and the user needs to wipe the whiteboard constantly, which will cause inconvenience in use

Faced with this situation, although various integral whiteboards can meet people's general requirements for use, they cannot satisfy both the convenience of use and the convenience of handling and carrying.

[0004] In addition, when users need to change the writing surface of ordinary double-sided whiteboards in general, people often need to move them by themselves, which is laborious and inconvenient.
