  • Patent number: 7575141
    Abstract: An actuator is arranged in a housing of an electrical nail gun. The actuator includes a sliding base, an external-running brushless direct current motor, a swing base and an electric driver. The sliding base is slidably disposed on an end of a located supporter which is positioned in the housing. The sliding base loads a spring and forms a hitting nail bar thereon. The motor has a stator and a rotator attached on an outer wall of the stator. A flywheel is driven by the motor and is configured to engage or disengage with/from the sliding base. The swing base is pivotally mounted on the housing. The swing base is adjacent to the sliding base and the supporter. The motor is installed in the swing base. The electric driver is attached to the housing and is adjacent to an end side of the swing base. The electric driver has a rod member driven by electricity.

  • Publication number: 20090095787
    Abstract: A transmission mechanism for an electric nail gun includes a linear transmission unit and a rotary transmission unit in a housing of the electric nail gun. The rotary transmission unit includes an electric driven driving wheel. The linear transmission unit includes a rack and a hitting bar. The hitting bar is disposed at a bottom of the linear transmission unit. The rack is in mesh with the driving wheel, slidably installed in the housing by a spring force, and configured to receive driving from the driving wheel and to drive the hitting bar to move linearly downward so as to hit a nail.

  • Patent number: 7506788
    Abstract: 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.

  • Publication number: 20090032567
    Abstract: 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.
