Power screw driver has motor driven feed with manual adjuster spindle to control fastener feed abutment

摘要

The power screw driver has a motor driven feed (2) to feed the fasteners sequentially into a drive position (31a). An adjuster (54,60) has an abutment (50) movable opposite to the feed drive direction, with an abutment face perpendicular to the feed direction. The actuator has a manually operated threaded spindle (60) which engages in the stop and by rotation causes the feed to operate steplessly.
