Detailed ways

Please refer to Figures 1 and 2. The utility model can dual-purpose projection desktop projector frame, which comprises a frame body 10 and a reflector 20; body. The frame body 10 is provided with a vertical support 11 and a horizontal seat 12 . In this embodiment, the vertical support 11 and the horizontal seat 12 are perpendicular to each other, and are formed by bending the same board 100 at 90 degrees. The vertical support 11 and the horizontal seat 12 can also be pivotally connected to form a state perpendicular to each other during use. The upper end of the vertical support 11 is provided with a first penetration hole 111; the two side walls 112 of the first penetration hole 111 are pivotally connected with the two sides 21 of the reflector 20 by a shaft 113 respectively, so that the reflector 20 can be doubled. The shaft 113 rotates an angle around the center; the vertical bracket 11 is further provided with a joint portion 13, such as a plurality of screw holes 131, for a plurality of screws 14 to pass through the screw holes 131 and screwed to the bottom edge 31 of the desktop projector 30.
