A transmission mechanism for an electrical nail gun includes a rotary transmission unit and a linear transmission unit in a housing of the electrical nail gun. The rotary transmission unit includes a motor driven by electricity, a flywheel driven by the motor and extending to form a cylinder thereon, a solenoid activated by electricity, and a moveable driving wheel adjacent to an end side of the cylinder. A clutch is formed between the cylinder and the driving wheel. The solenoid is buried in the cylinder so that a magnetic conductivity loop is constructed around the solenoid to produce the magnetic field when the solenoid is activated. The driving wheel is attracted to move to an engagement position to be driven by the flywheel, thereby driving the linear transmission unit to impact a nail when the solenoid is activated by electricity, and the driving wheel returns to a disengagement position to disengage from the flywheel, thereby stopping driving the linear transmission unit when the solenoid is demagnetized.

What is claimed is: 1. A transmission mechanism for an electrical nail gun, comprising: a rotary transmission unit in a housing of the electrical nail gun; and a linear transmission unit in the housing, comprising: a motor driven by electricity; a flywheel driven by the motor, the flywheel pivotall
What is claimed is: 1. A transmission mechanism for an electrical nail gun, comprising: a rotary transmission unit in a housing of the electrical nail gun; and a linear transmission unit in the housing, comprising: a motor driven by electricity; a flywheel driven by the motor, the flywheel pivotally mounted on a stop shaft, a cylinder extended from a side of the flywheel thereon and made of a magnetic material, and the cylinder defining a ring-shaped receiving chamber therein; a solenoid activated by electricity and buried in the receiving chamber, wherein a magnetic conductivity loop is constructed around the solenoid to produce the magnetic field when the solenoid is activated; and a moveable driving wheel rotatably disposed between an engagement position and a disengagement position adjacent to an end side of the cylinder, wherein two opposite slantwise end surfaces are respectively formed on the cylinder and the driving wheel to be used as a clutch; wherein the driving wheel is attracted to move to the engagement position to be driven by the flywheel, thereby driving the linear transmission unit to impact a nail when the solenoid is activated by electricity, and the driving wheel returns to the disengagement position to disengage from the flywheel, thereby stopping driving the linear transmission unit when the solenoid is demagnetized. 2. The transmission mechanism as described in claim 1, wherein a ring-shaped bearing, made of a magnetic material, is securely mounted on the stop shaft, and the solenoid is wrapped around an insulated ring stand, the ring stand is securely disposed on the stop shaft via the bearing. 3. The transmission mechanism as described in claim 1, wherein the solenoid is wrapped around the insulated ring stand, and securely disposed on the stop shaft. 4. The transmission mechanism as described in claim 1, further comprising a ring-shaped traction stand is moveably and pivotally mounted on the stop shaft, and the driving wheel is disposed on the traction stand. 5. The transmission mechanism as described in claim 4, wherein an end of the traction stand is formed to have at least a protruding block which is used to push the driving wheel to move towards the cylinder. 6. The transmission mechanism as described in claim 1, further comprising a ring-shaped disk stand, made of a magnetic material, is securely mounted on the stop shaft, a plurality of rolling posts is accommodated around the disk stand, and the driving wheel is moveably and pivotally disposed on the rolling posts. 7. The transmission mechanism as described in claim 1, further comprising an elastic member configured for exerting an acting force on the driving wheel, thereby pushing the driving wheel from the engagement position to the disengagement position, and the acting force should be less than an applied force which the magnetic field attracts the driving wheel to move. 8. The transmission mechanism as described in claim 7, wherein the elastic member is disposed between the ring-shaped bearing securely mounted on the stop shaft and the traction stand moveably and pivotally attached to the stop shaft. 9. The transmission mechanism as described in claim 7, wherein the elastic member is disposed between the ring-shaped disk stand securely mounted on the stop shaft and the driving wheel. 10. The transmission mechanism as described in claim 1, wherein the driving wheel is substantially a gear wheel, and the linear transmission unit at least comprises a rack in mesh with the gear wheel.
