Small-size air-cooled generator

The utility model discloses a small-size air-cooled generator, which comprises a generator box, a motor, an engine, heat dissipation grooves and a heat dissipation plate, the generator box is fixedly connected with the motor, the two ends of the generator box are both provided with the heat dissipation grooves, and the two ends of the heat dissipation plate are both fixedly connected with torsion spring pieces. The heat dissipation plate is connected with the heat dissipation groove through a torsion spring piece, and a sliding groove is formed in the inner wall of the heat dissipation groove. Through the arrangement of the heat dissipation plate and the push rod, the push rod drives the clamping block to move upwards on the inner wall of the sliding groove under the action of the spring, at the moment, the heat dissipation plate rotates, external air and internal air are circulated for heat dissipation, after use, a worker closes the protective top cover, the protective top cover pushes the push rod and the
