Description

Technical Field

[0001] The utility model relates to the technical field of ideological and political education, in particular to a teaching auxiliary device. Background Art

[0002] Ideological and political education auxiliary devices mainly play an auxiliary role in the teaching process, which can help students better understand the teaching content and improve the efficiency of teaching. As people pay more and more attention to ideological and political education, their requirements for ideological and political education auxiliary devices are also getting higher and higher. Auxiliary devices are often used in teaching. Through the combination of screen display and traditional blackboard, the effect of ideological and political education can be improved.

[0003] However, since teaching auxiliary devices usually use screens, compared to traditional blackboards, the surface of powered auxiliary devices will absorb more dust when in use. After long-term use, the dust on the surface of the display will affect students' visual effects of the display, which is not conducive to ideological and political education. In addition, the display screens of teaching auxiliary devices are usually large, which makes them more troublesome to move and take up a lot of space when idle. Utility Model Content
