Patent ID: 7905377

Claim:
A device for impacting a fastener comprising: a drive mechanism configured to impact a fastener; a flywheel pivotable between a first flywheel position whereat the flywheel is not in contact with the drive mechanism and a second flywheel position whereat the flywheel contacts the drive mechanism; a motor operably connected to the flywheel for storing energy in the flywheel; a trigger movable between a first released trigger position and a second trigger position; and a work contact element (WCE) assembly movable between a first released WCE position and a second WCE position, the WCE assembly configured such that (i) when the trigger is in the first released trigger position and the WCE assembly is in the first released WCE position, the WCE assembly mechanically engages the trigger to preclude movement of the trigger out of the first released trigger position, and (ii) when the WCE assembly is in the second WCE assembly position, the WCE assembly does not mechanically engage the trigger.
