1. A fastener driver comprising:
- a housing defining a handle portion;
a magazine in which fasteners are held;
a nosepiece for receiving fasteners from the magazine;
a driver blade movable from a ready position toward a driven position during which a fastener positioned in the nosepiece is driven into a workpiece;
a lifting mechanism operable to return the driver blade from the driven position toward the ready position for a subsequent fastener driving operation; and
a drivetrain to provide torque to the lifting mechanism,wherein at least a portion of the drivetrain is positioned within and extends through the handle portion of the housing.

11. A fastener driver comprising:
-
a nosepiece for receiving fasteners from a magazine; a driver blade movable from a ready position toward a driven position during which a fastener positioned in the nosepiece is driven into a workpiece; a lifting mechanism operable to return the driver blade from the driven position toward the ready position for a subsequent fastener driving operation; and a drivetrain to provide torque to the lifting mechanism, the drivetrain including an electric motor having a motor output shaft; a first gear box coupled to the motor output shaft to receive torque therefrom; a second gear box having an output shaft coupled to the lifting mechanism to provide torque thereto; and a drive shaft having a first end coupled to the first gear box and a second end coupled to the second gear box for transferring torque from the first gear box to the second gear box. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
