Career planning is also called "career planning". The quality of career planning will inevitably affect the entire life course. Career planning teaching mainly guides college students to establish correct values. During the teaching process, teachers need to display the food testing career planning instruction frame diagram on the display board. At the same time, teachers also need to explain the career planning draft designed by students during teaching. Therefore, display devices are needed.

[0003] The existing display devices have a simple structure, and most of them use blackboards or whiteboards for writing. Since there is a lot of content to be written, the carrying area of ​​the blackboard or whiteboard is limited, and it is impossible to fully present the career planning instruction framework diagram. Secondly, when it is necessary to explain and compare the career planning drafts designed by students, the content written by the teacher will be blocked, reducing the practicality of use. In view of the above problems, the existing equipment needs to be improved. Utility Model Content
