AI Technical Summary
In the laboratory of middle school or university, due to the reflection of multimedia displays, students cannot clearly see the content of the display, which affects the quality of classroom teaching; at the same time, there are too many students, and the teacher's experimental demonstration is difficult for every student to understand the experimental content and steps, which affects students' concentration and listening efficiency.
A teaching-specific student laboratory bench was designed, including support columns, fixing plates, foot pedals, light shields and display fixtures. The foot pedal drives the sliding column and fixed block to move, providing the function of shaking legs and refreshing; the light shield prevents external strong light from directly hitting the display to avoid reflection.
It effectively improves students' concentration in class, reduces the probability of classroom sleepiness, and avoids the reduced listening efficiency due to the reflection of the monitor.

Since the foot pedal is constructed as a telescopic plate, the length of the foot pedal is also changing when the top of the foot pedal descends. The foot pedal will drive the No. 2 fixed block and the sliding column to move downward through the No. 2 fixed axis. At this time, the bottom end of the sliding column will squeeze the spring, so that the spring is compressed and then rebounds, which can provide conditions for shaking the legs. The utility model provides a shading plate, and the shading plates on the left and right sides can effectively block the strong light from the outside from directly shining on the display, thereby avoiding the problem of reflection. The utility model can effectively improve students' concentration in class, reduce the probability of students feeling sleepy in class, and avoid reducing the efficiency of listening to classes in class due to reflection of the display. This has certain practicality. BRIEF DESCRIPTION OF THE DRAWINGS
