Abstract

A simplified fastening tool which uses the energy stored in a spring to install fasteners by an impact blow is disclosed. A housing body is preferably cast or molded. A one-piece plastic hand lever is pivotably attached to the body where the pivoting action is by sliding in a circular arcuate channel. A staple feeding track is slidably mounted to the bottom of the housing and includes a rear end element with forwardly extending resilient latching elements to secure the track. A hand grip opening extends forward up to the plunger and the hand lever is hinged at the rear of the housing.
