The fuel injection valve core is fixedly connected with the fuel injection valve extrusion head by a connecting rod through the fuel injection valve. The lower end of the position spring is fixed on the fuel injection valve, and the upper end is connected with the bottom surface of the injection valve extrusion head; the round body in the middle and lower part of the injection valve extrusion head, the return spring of the injection valve extrusion head, the fuel injection valve and the fuel injection The spool is set in the valve sleeve; the oil circuit control valve is set between the oil delivery pipe and the fuel injection valve, and the output of anti-rust oil and the spraying pressure into the fuel injection valve are controlled by adjusting the oil circuit control valve; when in use, turn on the compressed air switch , The compressed air enters the cylinder and the anti-rust oil tank at the same time. When the nail is hit and the nail is ejected from the nail channel, the anti-rust oil is sprayed from the nozzle and coated on the nail to form a layer of resistance on the surface of the nail. Oxidized film to avoid the loosening of components caused by the oxidation of gun nails.
