[0002] The display device for teaching experiments is a device for displaying experimental objects or related equipment during the teaching experiment process. Generally, it is a cabinet or panel storage display structure, which is very common in teaching. Among them, the teaching experiment display The device is most frequently used in the process of chemistry, physics or biology teaching experiments. In the process of biology teaching experiments, because it is impossible to directly display the living animals and plants, biological specimens will be placed in the display device for teachers to teach Use and help students fully understand biology-related knowledge, but the existing display devices for teaching experiments still have the foll
