Abstract
Abstract An automatic compressor-jack device which comprises an air compressor, a hydraulic jack and a transmission mechanism. The transmission mechanism, which is driven by a motor through a reduction gear, comprises an eccentrically disposed pin to connect to the piston rods of the cylinders of the compressor and the jack. Therefore, when the motor rotates, the transmission mechanism drives the air compressor and jack at the same time. That is, this one device allows the user two tire repair functions.
