[0002] As we all know, most of the explanation boards belong to the purpose of teachers' teaching and are widely used in various colleges and universities, while the student interactive explanation board is an auxiliary device used for discussion and explanation among several students in a small range; the existing The student interactive explanation board includes four sets of outriggers, a support board and a writing board. The tops of the four groups of outriggers are respectively connected to the left front, right front, left rear and right rear of the bottom of the support board, and the writing board is installed above the support board. When this kind of student interactive explanation board is used, the text is written through the writing board to complete the explanation interaction. During its use, it is found that due to the different needs of various students' heights and environmental requirements, the four sets of legs are fixed heights, and it is impossible to carry out height adjustments. And the adjustment of the horizontal angle leads to poor adaptability; and its function is very single, which leads to a relatively simple way of explaining and interacting
