In this application, when students watch the teacher's experimental teaching, the second table top 4 is placed horizontally on the upper end of the first table top 2. When the teacher's teaching is finished and the students need to complete the experiment independently, the second table top 4 is flipped to a vertical position, and the second table top 4 is limited and fixed by the limiting mechanism, and the two strip plates 9 are pulled so that the isolation layers 10 fixed on the side walls of the strip plates 9 are protected at both ends of the test bench, thereby effectively isolating multiple test tables, ensuring that students can complete the experimental operation independently, and preventing passing students from touching the experimental equipment and affecting the normal operation of the experiment.
[0025] The two support platforms 1 are both slidably provided with evenly arranged storage drawers 12 .
[0026] The lower side walls of the two support platforms 1 are fixedly provided with evenly arranged anti-skid support bases.
[0027] The limiting mechanism includes a screw rod 13, which is longitudinally rotated by a bearing and arranged inside the first cavity. A first handle 14 is fixedly arranged at the lower end of the screw rod 13, a lifting plate 15 is threadedly arranged on the rod wall of the screw rod 13, and a symmetrical plug rod 16 is fixedly arranged on the upper side wall of the lifting plate 15. A limiting plate 17 is fixedly arranged on the rear end of the upper side wall of the second table top 4.
