[0006] For the above-mentioned foldable projector, when the clamping plate is clamped by the fixed convex edge, the handle rod is used as a handle, which improves the convenience of carrying. When a bracket is needed, it is only necessary to remove the clamping plate and splice the two clamping plates into an X-shaped base through the splicing groove, and then rotate the threaded connecting column so that one threaded connecting column is connected to the plug-in hole and the other threaded connecting column is connected to the connecting hole, and the handle assembly can be used as a bracket. By using the handle assembly as a bracket, the convenience of storage is improved.

[0007] Furthermore, the handle rod is a telescopic rod.

[0008] Furthermore, the surface of the fixed protrusion is provided with an anti-slip structure.

[0009] Furthermore, the anti-slip structure is any one of an anti-slip protrusion or an anti-slip groove.

[0010] Furthermore, one end of the fixing protrusion is connected to the projector body, and the other end gradually extends downward.

[0011] Furthermore, an anti-slip pad is provided at one end of the clamping plate connected to the projector body. BRIEF DESCRIPTION OF THE DRAWINGS
