[0003] An existing cultural promotion and display device (Announcement No.: CN220962737U) has at least the following drawbacks:

[0004] In the aforementioned patent, manually rotating the turntable enhances audience participation and is suitable for immersive experiences in educational settings. If it is used to promote cultural exhibits, the baffle can be removed, and the exhibit can be placed between the left and right uprights. Adjusting the position of the left upright can fix the position of the exhibit. However, manually rotating the turntable requires a large amount of force, making it difficult for children / elderly to operate. At the same time, the display components cannot be modularly assembled and disassembled. When disassembling or assembling paper products or cultural exhibits, or when replacing damaged display components, each component must be operated sequentially, which is inconvenient. Therefore, it is necessary to propose a cultural promotion and display device to solve the above problems. Utility Model Content
