The experimental operation device can be moved to the other side of the workbench. The slider slides inside the slide slot. At this time, the slide plate can be slid out to replace the module, leaving more space for easy operation.

[0024] 2. When it is necessary to take out an item, the baffle is moved horizontally, and the baffle drives the connecting rod to pass through the through hole until the second magnetic sheet on one side of the limit plate is adsorbed with the first magnetic sheet. The connecting rod drives the pulling plate to move horizontally, and the pulling plate drives the rectangular rod to move horizontally. The rectangular rod is no longer in contact with the second rectangular hole. At this time, the drawer is no longer braked. If it is inconvenient to take out or put in items, the drawer can be pulled out and the items can be stored inside the drawer.

[0025] 3. According to the position of the items inside the drawer, move the fixed block and rotate the transparent turn plate to the appropriate position.
