[0002] The Science Popularization and Communication Department of the Science and Technology Museum mainly provides services to tourists in the exhibition hall, including explanations of exhibits, consultation and guidance, emergency handling, reporting of exhibit failures, etc. The popular science exhibits that need to be displayed generally need to be placed on display devices.

[0003] At present, the display devices on the market generally have a simple structure and can only serve as a display. When the display devices are moved or collided, the popular science exhibits are likely to fall and cause damage to the popular science products. For example, the Chinese utility model patent CN219306399U discloses a display cabinet for craft exhibits. The display cabinet uses an inner slide groove opened inside a turntable and a bidirectional lead screw that rotates and sleeves inside the inner slide groove. When the device needs to place a craft exhibit for display, the exhibit is first placed on the inner side of two sets of limit clamps according to the width of the exhibit, and the rotating handle outside the bidirectional lead screw is rotated, so that the bidirectional lead screw drives the limit clamp to adjust and shrink until the limit clamp clamps the craft exhibit to limit the position, thereby ensuring the protection and stability of the craft exhibit.

[0004] Existing science popularization exhibit display devices do not have a good fixing function. For example, the above-mentioned patent, although it can limit and fix the science popularization exhibits through clamping, its structure is relatively complex and will cover the science popularization exhibits, affecting their display effect. In addition, its fixing method is relatively cumbersome, has certain limitations, and is inconvenient to use. Utility Model Content
