Abstract

The invention discloses a convenient projector convenient to adjust. The projector comprises a housing which is provided with a control button; a storage battery which is installed in the cover shell, and connected with electric quantity display lamps arranged on the top and the side face of the cover shell; a damping rotating shaft, wherein the housing is hinged to the damping rotating shaft, and a rotating part of the damping rotating shaft is fixedly connected with the tail end of the housing; a base which comprises three supporting plates which define a square shape, wherein shell tubes extending upwards are arranged at the tail ends of the two longitudinal plates, telescopic inserting rods are installed in the shell tubes, and the inserting rods are connected with the fixing parts of the damping rotating shafts; and suckers which evenly distributed on the lower surface of the base. The housing and a projection lens can be rotated by any angle, and meanwhile, the height is adjusted through the inserting rod, so that projection is facilitated; and the suckers are arranged on the base to prevent a machine body from sliding, so that a projection picture is more stable.
