The upper end of the ball 14 is slidably connected in the slide groove 13.

[0025] When the photonic crystal showcase of holographic images is working, exhibits are placed on several moving seats 7, and the holographic projector 2 performs projection work. The photonic crystal transparent screen 3 is used to display the image information in the final display effect, which can realize the content playback and display of the information display. Other lights are arranged inside the supporting frame 1 to illuminate the exhibits inside, which are used to cooperate with the photonic crystal transparent screen 3 for better display. The effects of the lights inside the holographic projector 2 and the supporting frame 1 can be adjusted by programming, which are all prior arts. The electric push rod 12 is connected to an external power supply, and the electric push rod 12 can drive the moving seat 7 to move left and right. The upper ends of several balls 14 are slidably connected to the inside of the slide groove 13 under the moving seat 7. The balls 14 ensure the smoothness of the movement of the moving seat 7, which is convenient for subsequent work.

[0026] The suction assembly includes a moving tube 10, a limiting plate 16, a hose 17, an air pump 18, an air suction tube 19 and an air outlet tube 20. The air pump 18 is installed on the bottom surface of the inner wall of the installation box 22. The air suction tube 19 and the air outlet tube 20 are installed above and on the right side of the air pump 18, respectively. The moving tube 10 is provided with a plurality of roots and is respectively located inside a plurality of the moving seats 7. The moving tube 10 is connected with a plurality of adjacent suction cups 15. The rear end of the moving tube 10 passes through the exhibition stand 6 and the supporting frame 1 in sequence and is inserted into the installation box 22. The hose 17 is connected between the moving tube 10 and the air suction tube 19. The limiting plate 16 is connected to the right end of the outside of the moving tube 10.

When the user presses the moving seat 7 corresponding to the exhibit to be carefully observed, the user presses the button 5 corresponding to the moving seat 7 with his foot, as shown in FIG. Figure 3As shown, at this time, the electric push rod 12 corresponding to the moving seat 7 corresponding to the button 5 can drive the moving seat 7 to move leftward along the installation slot 8, and the moving seat 7 can move leftward along with the moving seat 7 to approach the photonic crystal transparent screen 3, so that the user can see the details of the exhibits more clearly through the photonic crystal transparent screen 3, which is convenient for the user to better observe the exhibits and improve the display effect and interactivity;

[0030] like Figure 4 As shown, as the moving tube 10 moves to the left, the limit plate 16 on the moving tube 10 can fit with the left side of the inner wall of the installation box 22. The setting of the limit plate 16 can prevent the moving seat 7 from continuing to move to the left and limit the moving seat 7. The user can also set the stroke of the electric push rod 12 inside the PLC controller 21 to prevent the moving seat 7 from colliding with the photonic crystal transparent screen 3 and causing damage to the photonic crystal transparent screen 3.

[0031] After the user leaves, the human body sensor 4 can no longer sense the person and transmits the signal to the PLC controller 21. The PLC controller 21 can then control all the electric push rods 12 to drive the moving seat 7 to move right and return to its original position. At the same time, the control button 5 stops working to avoid accidental touches. The next time a user approaches, the operation can continue according to the above steps.
