Abstract:
1. A device for attaching fasteners comprising: a casing having a grip; a lever supported by the casing rotatably about an upper end of the lever and urged forward; a link arm actuated by the rotation of the lever; a piston engaged slidably by an upper end of the link arm; a driving rod slidable with the piston; a hollow needle situated at a leading end of the driving rod and having a slit; and an assembly fitting guide that is formed behind the hollow needle and that is adapted to fit an assembly of plastic fasteners; wherein a removable guide attachment, which is changeable with another removable guide attachment, is removably held below the assembly fitting guide and is adapted to guide a connecting bar in the assembly in an ejection direction; wherein the casing has an ejection guide groove that is formed on one side thereof and that is adapted to guide ejection of the connecting bar of the assembly, wherein the removable guide attachment has a curved surface directed toward the ejection guide groove, wherein the casing has a first hole connected with the ejection guide groove, and wherein the lever has a second hole so that the connecting bar is passable through the first and second holes; and wherein the second hole formed in the lever is adapted to have a part of the removable guide attachment inserted therein so that a rounded inner surface of the second hole is brought into sliding contact with an outer surface of the inserted part of the removable guide attachment upon the rotation of the lever such that any clearance is prevented from occurring therebetween.
