<p>The present invention relates to a pneumatically nailing machine using cot gas. A connection screw is connected with a sub-piston in a housing of the nailing machine and a rear end of the housing is connected to a hammer seat. A retainer is inserted into an inner chamber of a front end of the housing. Moreover, a moveable joint is inserted into a hole located in the retainer and there is a spring between the retainer and the joint. A switch is positioned into a chamber of the joint. A front cover plate can be fixed in an outer cylinder and a main piston is located in the front of an inner cylinder. Said main piston is provided in the right of a firing pin. Said sub-piston is positioned in the outer cylinder. Above a downward protrusion of the switch, there located a trigger whose front end is contact with a sliding pin. An inlet port is screwed into a transition duct. A gas cylinder is provided between the transition duct and the inlet port. Said nailing machine according to the present invention takes co2 gas as the power source without electric power and compressed air. Therefore, it is used for a moveable operation and has no noise and good seal performance.</p> |
