Abstract: A nail gun, comprising a first piston moveably disposed in the first cylinder, a second piston moveably disposed in the second cylinder, a driving ram, a pawl, a linear motion actuator electrically coupled to the control circuit unit, the linear motion actuator capable of driving the pawl to retain or release the driving ram. The adjustment button is configured to select a selected pressure rating of the pressure ratings, during the compression stroke, the pawl retains the driving ram, and the control circuit unit is configured to calculate a predetermined distance value of the second piston and control the second piston to move and form a predetermined compressing pressure in the second working chamber. The control circuit unit is configured to control the linear motion actuator to release the driving ram when the second piston moves the predetermined distance.
