Abstract: A high-pressure nail gun with a switched exhaust system, including: a machine housing; a pneumatic unit, installed in the machine body to complete a nail-hitting operation using barometric pressure; a switching valve set, controls positive airflow for operating in the pneumatic unit and controls reverse airflow for discharging from the machine body; a flow channel unit, formed in the machine body. The flow channel unit is to guide positive and reverse airflow, having an expansion flow channel that connects to the switching valve set and extends along the circumference of the machine body. The expansion flow channel is provided to guide the exhausted reverse airflow for extending an appropriate length of the expansion flow channel to reduce air pressure and air flow rate for reducing noise levels.
