Problems solved by technology

[0002] Blackboards for teaching are an indispensable tool in teaching. Generally, blackboards are installed in every classroom of every school. The blackboards installed in the classroom are generally fixed on the wall by bolts, screws and other fasteners. Fasteners such as bolts and screws need to be provided with multiple mounting holes on the wall, which will cause damage to the classroom walls, and the use of bolts and screws to fix and connect them is prone to defects such as loosening and loosening during long-term use. It is necessary to process the matching thread structure, so it is easy to cause structural damage and shorten the service life. When the blackboard is damaged and needs to be replaced, it is troublesome to disassemble due to the use of multiple fasteners for installation. The installation and replacement of the blackboard Extremely inconvenient and low installation and replacement efficiency
