When comparing, the lighting lamp 16 can be turned on to provide lighting for the light-transmitting glass plate 10. When working, the wireless signal module 5 is wirelessly connected with the external device, and the electric screw rod 24 is started through PLC programming. The output end of the electric screw rod 24 drives the U-shaped plate 26 to slide in the guide rail 20 to adjust the vertical position.

When the display frame 1 needs to be stored after use, the operator can rotate the one-way screw rod 11. The rotation of the one-way screw rod 11 drives the slider 12 to rotate. The rotation of the slider 12 drives the slider 12 and the fixed tube 13 to slide in the support tube 2, so that the connecting rod 14 slides in the fixed tube 13 for adjustment. The connecting rod 14 moves in the direction close to the avoidance groove 9 to adjust the storage angle of the display frame 1. With the above structure, a pair of design drawings on the display stand can be intuitively compared, reducing the burden of left-right comparison for viewers.
