[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0029] Specific implementation method one: Combining Figure 1-8 As shown, an easy-to-use projector includes: a hanging frame 1, a guide protrusion 101 above the hanging frame 1, and a rack 102 below the hanging frame 1. Multiple hanging frames 1 can be spliced ​​together in sequence to form a track for the displacement of a fixed frame 2. The fixed frame 2 has an overall U-shaped structure, which can avoid displacement interference with the hanging frame 1. At the same time, a support member 3 connected to the guide protrusion 101 is provided above the fixed frame 2. A drive assembly 4 is provided below the fixed frame 2, and the drive assembly 4 can be displaced along the height direction. The projector body 5 is provided on the fixed frame 2 on one side of the drive assembly 4.

[0030] A projection screen is laid on top of the display case. During the presentation, the drive component 4 moves the projector body 5 to follow the movement and play images of items in various positions, meeting the usage requirements. This greatly reduces the number of projectors needed, lowers the setup cost, and simplifies the setup scene. For temporary exhibition halls, the traditional multi-projector setup is too expensive and complicated. With this device, only the hanging bracket 1 and the projector body 5 need to be set up according to the display area, which facilitates cost control and improves setup efficiency. Moreover, multiple projector bodies 5 can be set up at the same time, which is convenient to adjust according to the setup requirements.
