The elastic anti-skid strip 13 on one end of the support frame 11 is softly overlapped on the desktop. The elastic anti-skid strip 13 and the anti-skid soft block 19 are used to increase the friction and anti-skid strength between the desktop and the support frame 11. A hand grip 12 is provided on the top right side of the support frame 11 to prevent the projector 16 from excessively contacting the outside world, and the support frame 11 is then held by the hand grip 12.
