The support plate 302 is fixedly installed on the lower surface of the piston of the electric telescopic rod 301.

[0022] In this embodiment, the piston of the electric telescopic rod 301 drives the support plate 302 to move downward, so that the lower surface of the support plate 302 is lower than the lower surface of the roller 2, which facilitates the stable placement of the display device.

[0023] Specifically, the first lifting mechanism 4 includes an electric linear module 401 and a fixed block 402. The electric linear module 401 is fixedly installed on the lower inner wall of the box body 1.

[0033] When in use, the concealed lock 10 opens the box door 9 at the same time, and the control box 803 is used to make the left and right electric linear modules 401 slide in the first lifting mechanism 4 drive the fixed block 402 to move upward, so that the fixed block 402 drives the transparent protective cover 5 to move upward, and the transparent protective cover 5 moves to the uppermost position, and the popular science design works are placed on the placement plate 802 of the placement mechanism 8, and then the second lifting mechanism 6 drives the rectangular frame 7 to move upward, and the rectangular frame 7 drives the popular science design works on the upper surface of the placement mechanism 8 to move upward, so that it leaks out of the upper surface of the box body 1, and then the control box 803 is used to make the reduction motor 801 work, and the output shaft of the reduction motor 801 drives the placement mechanism 8 to move upward. The plate 802 rotates, and the placement plate 802 drives the popular science design works to rotate, and then the box door 9 is closed by the hidden lock 10. After the display is completed, the second lifting mechanism 6 first drives the placement mechanism 8 on the rectangular frame 7 to reset, and then drives the transparent protective cover 5 to reset through the first lifting mechanism 4, thereby increasing the transparent protective cover 5 function of the display device itself, which can effectively isolate and protect the exhibits, and facilitate the storage of the transparent protective cover 5, reduce the volume of the display device, facilitate folding and transportation, increase the rotating display function of the exhibits, facilitate people to watch at different angles, enable the placement mechanism 8 to be able to rise and fall, facilitate the folding of the exhibits, reduce the volume of the display device, and facilitate folding and transportation.
