The limiting circular plate 20 pushes the supporting spring body 24 to shrink. The limiting circular plate 20 drives the fixed spring body 24 to shrink. The positioning cylinder 21 slides and contracts, so that the combined frame 17 slides into the supporting straight plate 14 for installation.

The servo motor 6 can be connected with the positioning notch 4 through the limit driving column 7. The servo motor 6 drives the supporting turntable 3 to rotate through the limit driving column 7. The supporting turntable 3 rotates smoothly on the supporting square frame 1 through the ball body 5 and the connecting through hole 2, which is convenient for the supporting turntable 3 to drive the holographic projection display cabinet 16 to rotate and adjust through the supporting column 8 and the supporting stud 12 to display in different directions. Four groups of holographic projection display cabinets 16 are installed at the same time, which can display the details of the object, and the servo motor 6 performs repeated left and right rotation movements to avoid the phenomenon of wire winding. The servo motor 6 is a known and existing technology on the market and will not be described in detail.
