Technical effects and advantages of the utility model:

1. By setting the encoder, when the motor is working, the reducer will convert the high speed of the motor into a low speed, and then transmit it to the lifting component and the turntable through the second wheel, thereby driving the exhibits on the turntable to rotate. When the second wheel rotates, it will drive the first wheel to rotate through the belt. At this time, the encoder will record the rotation direction and angle of the first wheel and convert it into a pulse signal. The encoder transmits the pulse signal to the controller, and the controller loads the pulse signal into USB data and transmits it to the computer host that controls the virtual background externally. Then the computer host changes the angle of the virtual background according to the analyzed rotation direction and angle, so that the virtual background can output the background picture of synchronous movement in real time with the rotation of the display stand, making the shooting background more realistic, while increasing the authenticity of the shooting background and controlling the cost;

2. Because the displayed items have different volumes, it is easy for the displayed items to not be in the middle of the picture, resulting in poor shooting effects. The shooting personnel need to constantly adjust the camera position, which increases the tediousness of the staff's work. Therefore, by setting a lifting component, when the displayed item is small in size, the electric telescopic rod is controlled to work. At this time, the electric telescopic rod pushes the connecting tube and the turntable to rise, thereby driving the third lifting tube, the second lifting tube, and the first lifting tube to rise. Because the first clamping block, the first clamping slot, the first slide slot, the first sliding bar, the second slide slot, the second sliding bar, the third slide slot, the third sliding bar, the fourth slide slot, and the fourth sliding bar are provided, the second rotating wheel can drive the support plate to rotate when it is transmitted upward one section at a time, so that the lifting component can not only drive the turntable to rotate, but also realize the rise of the turntable. In actual use, the number of the first lifting tube, the second lifting tube, and the third lifting tube can be increased or reduced according to the shooting requirements, and the first lifting tube, the second lifting tube, and the third lifting tube are provided to increase the stability of the turntable when it rotates, so as to avoid the situation where the exhibit is tilted and the rotation is unstable.
