Also can be fixed with the joint in being convenient for pull out, also be convenient for accomodate, also be convenient for just also shift and transport, can be convenient for use in more use scenes, have the characteristics of more functionality equally.

On the other hand, the invention can fold and erect the display component by arranging the display component when in use, and then connect with an external teacher portable computer through the host computer to realize audio-visual teaching. When the students need to be shown that some multimedia has no content or step, the writing component 5 can be pulled out from the board opening 3, and normal writing teaching can be realized after the writing component is fixed. Of course, the teaching can be carried out while the two are combined, the complementarity applicability is good, and the teaching effect is favorably improved. In the teaching process, can utilize hydraulic stem 10 to release workstation 60, realize with 2 parallel and level of operation panel, be favorable to mr's normal teaching. Meanwhile, the seat 11 can be suitable as required, the seat 11 can be taken or rejected aiming at different use environments, and additional supply is not needed. The display assembly, the writing assembly 5, the workbench 60 and the seat 11 can be stored, and the storage is conveniently and rapidly realized in the later arrangement and storage process, so that the size is greatly reduced, the transfer and the transportation are convenient, and the applicability of the invention is improved. The invention has uncomplicated structural principle, and the technical scheme of the invention is easy to understand by technicians in the field and is suitable for popularization in the field.

In summary, embodiments of the present invention provide an audiovisual teaching device, which can provide a solution to the deficiencies in the prior art, and has the characteristics of various functions and high applicability in use. Has better market promotion prospect and is very suitable for popularization and use in the technical field of teaching.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
