ABSTRACT:
An intake control valve assembly of a rivet-nut gun comprises mainly a handle and a pressure accumulator; the top of the pressure accumulator is furnished with a valve cylinder, in which an intake control valve assembly is loaded; by means of a trigger, the pressure air can be guided to flow via the intake control valve assembly and into the pressure accumulator so as to push a piston in the pressure accumulator to move up; by means of the piston rod moving in the hydraulic chamber, a hydraulic pressure is generated to facilitate a pull rod to perform riveting work.
