Controlling operation time of an electric nailer, has controller with a time-travel control unit connected to the DC power source, and a driving unit linked to electromagnetic coils

摘要

The nailer has a power source (20), an electromagnetic coil (30), a control unit (40), and a moving member (50), all of which are in the electric tool housing. The power source generates DC power for a predetermined voltage value that provides the power for the electromagnetic coil and the control unit, for enabling them to generate electromagnetic forces and actuate respectively. The control unit controls the output of the DC power source at a standard reference potential or predetermined potential, so that the control unit can actuate the electromagnetic coils at any period of time. The driving unit includes three voltage divider resistances and four driving transistors.
