  • Publication number: 20080272170
    Abstract: The present invention relates to an AC electric nail-gun and method thereof. The AC electric nail-gun of the present invention is mainly provided with an integrated circuit (IC), and the IC is connected with a SCR (silicon controlled rectifier) drive circuit such that an actuating magnetic coil is activated by the driving of the SCR drive circuit through a SCR commanded by the IC. By means of the activating, the striker pin of the impact plunger within the actuating magnetic coil beats nail into wood. If an appropriate calculation conducted by the IC according to the reaction force obtained by the striker pin shows that the nail is not firmly beaten into wood, the impact plunger is commanded to allow the striker pin beat nail again before the plunger is brought back to its original position to be activated.
