ABSTRACT:
A fastener applicator, for example for cable clips, uses the kinetic energy of a flywheel rotated by a prime mover, preferably a battery driven electric motor, to drive a striker for firing a fastener into a support. An actuator which strikes the striker may be a fixed projection on the flywheel or be an element on the flywheel movable relative to the flywheel by centrifugal force to project the actuator from an inoperative position to an operative position for striking the striker. The drive from the prime mover to the flywheel is through a clutch or releasable drive coupling which temporarily disconnects the drive when the actuator strikes the striker so that the kinetic energy at the flywheel alone drives the striker and the prime mover is protected from the impact. A micro-processor measures the rotational speed of the flywheel and stops the prime mover when a pre-determined speed for the necessary kinetic energy is achieved.
