Because the imaging mirror surface 3 and the projector 2 are all placed in an open mode when projection is carried out, dust in air inevitably falls on the base 1, when the imaging mirror surface 3 is calibrated, the movement of each component can lead to the fluctuation of dust which is kept on the base 1, therefore, when the connecting frame 4 moves upwards, the friction rod 20 can be driven to move upwards, the friction rod 20 rubs on the electrostatic plate 19, static electricity for adsorbing dust is generated on the electrostatic plate 19 through a friction static electricity principle, the static plate 19 adsorbs the fluctuant dust together, and the dust is prevented from floating on the imaging mirror surface 3 when the lens is calibrated, so that the projection effect of the imaging mirror surface 3 is affected.
