An electric nail-attaching mechanism and an electric coil nail gun using the mechanism

Abstract

This invention relates to an electric nail-feeding mechanism and an electric coil nail gun employing the same mechanism, belonging to the field of tool technology. The coil nail gun includes an energy storage mechanism, an impact mechanism, a nail-driving mechanism, a lifting mechanism, and a nail-feeding mechanism. The drive wheel has a cam profile; one end of a transmission rod forming a sliding pair with the frame forms a cam pair with the cam profile; the other end of the transmission rod is fixed to a drive block with a drive ramp; the drive ramp remains in contact with the lower surface of the floating base of the nail-feeding claw; the floating base of the nail-feeding claw tends to a stop position, one end is hinged to the nozzle near the nail-driving channel, and the other end is hinged to a floating claw tending to a limiting position; the arc-shaped raised end of the floating claw away from the hinge is in the nail-feeding channel. The invention directly drives the nail-feeding claw through the transmission rod via the drive wheel, thus reducing transmission links and avoiding the influence of the impact pin movement, resulting in a very stable and reliable nail-feeding process.
