s3, when the convex-concave lens (49) retracts into the fixed shell (1) after being used, the second motor (32) is started, the output shaft of the second motor (32) drives the rotating hairbrush (33) to rotate, the rotating hairbrush (33) wets the rotating hairbrush (33) under the action of the cleaning water bin (35) and the fixed pipe (36), the convex-concave lens (49) is cleaned by the rotating hairbrush (33), and when the rotating hairbrush (33) rotates, the rotating hairbrush (33) cleans sundries in the rotating hairbrush (33) into the collecting bin (34) under the action of the baffle (37);
s4, when the angle of the projection lens (23) is insufficient, when the telescopic rod (52) is extended, the telescopic rod (52) moves one end of the second supporting rod (53) in the sliding groove (51), the second spring (55) and the movable block (56) at one end of the second supporting rod (53) are fixed in the movable hole (57), and when the second supporting rod (53) moves, the sliding groove (51) rotates out of the fixed stable groove (54), so that the projection angle is selected.
