Abstract
A dynamic clutch apparatus for an electrical nail gun includes a pair of symmetric direct stroke apertures formed on a gun body support; a firing pin set slidably installed on a side of the gun body support; a guiding base movably installed inside the gun body support; a pair of symmetric oblique stroke apertures formed on the guiding base. Aperture walls of the oblique and direct stroke apertures encircle and form an interconnected through aperture. Two pivot bearings are slidably installed inside the through aperture. A flywheel for accumulating kinetic energy is installed between the pivot bearings coaxially. An electromagnetic driver drives the guiding base to move, causing the through aperture to restrict the pivot bearings and the flywheel to move and press the firing pin set. Then, the firing pin set passes nail-percussion kinetic energy along a nail-percussion axial direction.
