摘要： A powered hand-held fastening tool includes a housing defining a handle, a frame, a motor-driven flywheel journaled to the frame, and an elongated driver that is selectively coupled to the flywheel to drive a fastener into a workpiece. A follower assembly for selectively coupling the driver to the flywheel includes a solenoid actuator, a biasing mechanism, a lever arm connected between the solenoid actuator and the biasing mechanism, and an intermediate member having journaled thereto a pivot roller and a pinch roller. Upon energization of the solenoid the lever arm is moved in a direction parallel to the drive axis, thereby applying a force on the pivot roller perpendicular to the drive axis, causing the pinch roller to press the driver against the flywheel and initiate the drive stroke. The intermediate member pivots about the pivot roller to release the pressure on driver upon completion of the drive stroke.

摘要： A powered tool follower assembly can include a solenoid plunger that is movable longitudinally in a direction aligned with a drive axis in response to energization of the solenoid and a biasing mechanism with a spring axis extending transversely to the drive axis. A lever arm can extend between the plunger and the biasing member and couple the plunger to the biasing mechanism. A pinch roller can be disposed between the lever arm and the driver. Energization of the solenoid can move the plunger longitudinally, causing relative movement between the lever arm and the drive wheel that forces the pinch roller into engagement with the driver and transfers a biasing force from the compression spring through the lever arm and pinch roller to the driver to pinch the driver between the pinch roller and the flywheel and drive the driver along the driver axis.

摘要： A powered hand-held fastening tool includes a housing defining a handle, a frame, a motor-driven flywheel journaled to the frame, and an elongated driver that is selectively coupled to the flywheel to drive a fastener into a workpiece. The flywheel and driver have complementary sloped surfaces that mesh with each other to transmit energy from the flywheel to the driver to accelerate the driver along the driver axis. A follower assembly for selectively coupling the driver to the flywheel includes a solenoid actuator.
