[0002] A whiteboard is a common tool for teaching, meeting discussions, and personal and family note-taking. It is usually made of an erasable white surface that can be written on with a dry-erase pen. Whiteboards have a wide range of uses and can be used to display and explain teaching content, record key points of meeting discussions, and take memos or messages at home. Whiteboards in the prior art are basically flat. Flat glass whiteboards are more common, including tempered glass, glue, and iron sheets. When installing, holes are drilled in the wall, expansion screws are inserted into the holes, and screws are screwed into the expansion screws through the four holes on the glass plate to fix the board. This type of flat whiteboard has the following defects: Since the surface of the whiteboard is flat, it is necessary to adjust the standing posture and wrist angle when writing to the bottom, the utilization rate of the bottom of the board is low, and writing is uncomfortable.
