Abstract
An impact enhancing device of an electric nailer, comprising: an AC power source, a protection circuit, a first switch, a full-wave rectifier, a timing controller circuit, an energy-storage circuit, a solid-state switch circuit, an electro-magnetic coil device, a DC power source, a second switch, a reset enable single shot trigger circuit, and a relay. Thus, the electric nailer provides a larger impact force with a smaller volume and a lighter weight.
