Abstract
The present device relates to an inlet of a blow gun, and more particularly to a metal inlet combined in a plastic blow gun by injection molding. The metal inlet has an internal screw hole, and a polygonal outside surface or a ratchet-striated outside surface, to provide a high torque-resistant construction when integrally molded with the blow gun. One or more groove rings are formed in the outside surface of the metal inlet, the side walls of the groove ring form retainers to prevent it from moving out axially under a large axial force. The plastic blow gun integrated with the metal inlet has an excellent seal efficiency without any leakage, and the service life is increased greatly.
