[0002] In the field of teaching, the experimental box, as an important teaching auxiliary tool, is widely used in various types of experimental teaching.

[0003] Traditional experimental boxes usually have fixed sizes and heights, and cannot be adjusted according to teaching needs or students' observation angles. This results in that during experimental teaching, if the height of the experimental box is too high or too low, students will find it difficult to clearly see the operation details in the experimental box, which affects their understanding and mastery of the experimental content. In addition, most traditional experimental boxes lack the function of adjusting the display angle, and cannot adjust the display angle according to teaching needs or students' observation habits, which further affects the teaching effect. For this reason, we propose an experimental box for teaching. Utility Model Content
