The projector body 21 can also be carried by hanging, and the first rotating components 221a, 22A and the second rotating component 2jS] 201133119 are coupled to the frame bodies 225, 225b. Here, the first rotating components 22U, 22ib and the second rotating component 223 are all coupled with the frame bodies 225, 225b, which are not limited, and may of course be only the first rotating component 221a, 221b or the second rotating component. 223 is coupled to the frames 225 and 225b. Similarly, the other end S1 of the first rotating assembly 221a, 221b can be connected to the surrounding environment (e.g., table top or floor) by, for example, bonding, snapping, locking, screwing, fitting, fusing, or welding. Thereby, the connection manner of the projection devices 2a, 2b to the surrounding environment can be further increased. In addition, in the embodiment, the projection devices 2a, 2b may further include a distance measuring unit 23 and a focus control unit 24.
