ABSTRACT:
An attachment for a portable power screwdriver allowing a workman to drive screws from a stand-up position. A telescoping driving tube is associated with a power driver and the tube being joined to a feed tube in the region of a nose section. The feed tube includes an escapement device which is responsive to a reciprocating movement of a cam fixed on an upper driving tube portion relative to a lower driving tube portion to ensure a non-jamming feeding of fasteners to the nosepiece.
