[0002] At present, for the convenience of publicity, people often set up different devices or system structures in exhibition halls to attract customers, increase users' attention to products, and in the process, keep users' experience as comfortable as possible.

[0003] In order to make more exhibitors understand the information of the products on display, large exhibition halls now generally use display screens to display product information, making it easier for the audience to understand the designer's ideas. However, the existing display screens are usually fixed on the wall for display, and the display screens cannot be moved for display, and cannot achieve a good display effect.

[0004] Later, a method of using curtain rails to move the display screen appeared on the market, which was directly connected to the driving wheel through the output shaft of the motor. If the inner hole processing accuracy of the driving wheel and the motor output shaft is not enough, the concentricity difference will cause the motor output shaft and the driving wheel shaft to be non-concentric, the motor will be twisted when running, there will be noise when rotating and the stability of operation will be greatly reduced.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
