A clutch mechanism arranged in a housing of an electrical nail gun includes a sliding base, a driver driven by electricity, a swing base pivotally mounted on the housing, and an electric driver attached to the housing and being adjacent to an end side of the swing base. The sliding base is slidably disposed on an end of a free roller positioned in the housing, and the sliding base loads a spring and forms a hitting nail bar thereon. The driver has a motor and a flywheel driven by the motor, and the flywheel is configured to engage or disengage with/from the sliding base. The swing base is adjacent to the sliding base and the free roller and receives the driver therein. The electric driver has a rod member driven by electricity, and 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. Thus, it is an advantage to improve service life and stability of the electrical nail gun.

What is claimed is: 1. 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. 2. The clutch mechanism as described in claim 1, wherein at least one extension spring is disposed on the sliding base, the at least one extension spring connects a positioning post in the housing with the sliding base. 3. The clutch mechanism as described in claim 1, wherein the sliding base is fixedly mounted on a sliding table which is slidably mounted on at least one guiding post in the housing, and a compression spring is displaced around the at least one guiding post for resisting against the sliding table to thereby load the compression spring on the sliding base. 4. The clutch mechanism as described in claim 1, wherein a side surface of the sliding base defines a plurality of linear grooves therein, and the flywheel defines a plurality of ring-shaped or sector-shaped grooves therein for mesh with the linear grooves of the sliding base. 5. The clutch mechanism as described in claim 1, wherein the swing base is rotatably mounted on a post axis in the housing, and the flywheel is adjacent to end sides of the sliding base and the free roller. 6. The clutch mechanism as described in claim 5, wherein the swing base is formed to have an arm portion thereon. 7. The clutch mechanism as described in claim 6, wherein an extension plate extends out from the swing base, and the rod member pushes the extension to thereby drive the swing base to swing from the second position to the first position. 8. The clutch mechanism as described in claim 1, wherein the flywheel is securely mounted on a central axis of the motor for being driven by the motor. 9. The clutch mechanism as described in claim 1, wherein the motor is disposed on a side of the flywheel for driving the flywheel to rotate. 10. The clutch mechanism as described in claim 9, wherein the swing base is formed to have a ring portion thereon for receiving the motor therein, and the flywheel is disposed on the swing base and adjacent to opposite end sides of the sliding base and the free roller. 11. The clutch mechanism as described in claim 10, wherein the swing base is formed to have an arm portion thereon. 12. The clutch mechanism as described in claim 11, wherein an extension plate extends out from the swing base, and the rod member pushes the extension to thereby drive the swing base to swing from the second position to the first position. 13. The clutch mechanism as described in claim 1, wherein the swing base is formed to have an arm portion thereon. 14. The clutch mechanism as described in claim 1, wherein the electric driver is an electro-magnetic driver. 15. The clutch mechanism as described in claim 1, wherein an extension plate extends out from the swing base, and the rod member pushes the extension to thereby drive the swing base to swing from the second position to the first position. 16. The clutch mechanism as described in claim 15, wherein an elastic member is disposed between the extension plate and an end wall of the housing for driving the swing base to swing from the first position to the second position. 17. The clutch mechanism as described in claim 15, wherein the rod member is connected to the extension plate for driving the swing base to swing between the first position and the second position.
