Abstract
A tool for dispensing plastic fasteners from a fastener clip includes a housing, a trigger pivotally mounted in the housing, a hollow slotted needle slidably mounted in the housing, an ejector rod disposed to insert back and forth through the hollow needle and an indexing mechanism for advancing the cross-bar of a fastener in the fastener clip into axial alignment behind the needle. The indexing mechanism includes a feed slide coupled to the trigger and a pivotally mounted feed cam connected to the feed slide, the feed cam including a pair of spaced apart projections. A metal feed pawl includes a ratchet shaped tooth and is disposed against the feed cam in a fitted relationship between the pair of projections. A spring mounted on the feed pawl resiliently urges the ratchet tooth into continuous contact with the fastener clip to prevent a jamming condition.
