Abstract
A transmission mechanism of an air compressor contains: a piston, a torque gear, a connection rod rotatably connected with the piston, a cylinder configured to accommodate the piston, wherein a central orifice of the torque gear corresponds to an internal ring of a bearing in a second positioning orifice of a base, and a screw bolt is inserted through the torque gear to screw with the central orifice from the internal ring of the bearing, such that the torque gear matingly contacts with the bearing along the screw bolt, and the bearing is not broken, thus moving the piston in the cylinder stably.
