Abstract
An attachment for a staple gun tacker having a staple driving blade is disclosed which is adapted to be used in driving and setting a rivet of the type having a pin member mounted in a headed rivet shank having an expandable workpiece piercing free end. The attachment includes a housing adapted to be frictionally engaged on the working end of a staple gun tacker and having a bore located to be generally in axial alignment with the driving blade of the staple gun tacker. A hollow flanged bushing is slidably mounted in the housing bore with a spring for biasing the bushing away from the housing to engage the shoulder of the interior of the housing and to permit retraction of the bushing into the housing against the bias of the spring. A pin punch which is axially free floating within its operative range of movement is slidably mounted in the bushing for axial movement therein. The pin punch is axially restrained to prevent the pin punch from exceeding its operative range and to prevent inadvertent removal of the pin punch from the attachment housing when the attachment is removed from the staple gun tacker. The bushing and the pin punch are positioned such that the pin punch is impacted by the driving blade of the staple gun tacker when it is operated to apply a driving force thereto, which force is used to drive the pin member of the rivet to expand the free end of the rivet.
