Claim:
A clutch mechanism arranged in a housing of an electrical nail gun comprising: a sliding base slidably disposed on an end of a free roller positioned in the housing, the sliding base loading a spring and forming a hitting nail bar thereon; a driver driven by electricity, the driver having a motor and a flywheel driven by the motor, the flywheel being configured to engage or disengage with/from the sliding base; a swing base pivotally mounted on the housing, the swing base being adjacent to the sliding base and the free roller and receiving the driver therein; and an electric driver attached to the housing and being adjacent to an end side of the swing base, the electric driver having a rod member driven by electricity, wherein the rod member drives the swing base to swing to a first position where the flywheel meshes with the sliding base to thereby drive the sliding base to move downwards, and a second position where the flywheel disengages from the sliding base to thereby cause the sliding base to reposit.
