ABSTRACT:
In a fastener-driving tool comprising a housing structure and a magazine, a structure fixed to the nosepiece is adapted to confine one of two sides of a leading portion of a strip of fasteners so as to guide the leading portion of the strip along fastener-guiding surfaces of the fixed structure. Moreover, a structure hinged to the nosepiece is adapted to be hingedly moved between an operative position and inoperative positions and is adapted when disposed in the operative position to confine the other side of the leading portion of the strip so as to guide the leading portion of the strip along fastener-guiding surfaces of the hinged structure. The hinged structure includes a polymeric cover hinged to the nosepiece, a holding member, and two wear guards, which are spaced one above the other, which are made of metal, and which are mounted so as to define the guiding surfaces of the hinged structure. In one contemplated embodiment, the polymeric cover has two rails spaced one above the other, and each wear guard is slidable on insert molded onto one of the rails. In another contemplated embodiment, the polymeric cover, the holding member, and the wear guards are hinged independently to the nosepiece about a common axis.
