  • Publication number: 20200102953
    Abstract: An air compressor contains: a torque gear on which a central orifice and a connection rod are arranged. The central orifice has screw threads defined thereon and corresponds to one of multiple positioning orifices of a base, the one positioning orifice is configured to accommodate a bearing, and a screw bolt is inserted through the bearing in the base so as to screw with the central orifice via the torque gear. The connection rod of the torque gear is rotatably connected with a piston so that the piston moves in a cylinder to produce compressed air, the torque gear matingly contacts with the bearing along the screw bolt, and the bearing is not broken in the one positioning orifice, thus moving the piston in the cylinder reciprocately.
