Abstract:
1. A power-driven nailing machine comprising: a driving cylinder; a driving piston slidably housed within the driving cylinder; a driver coupled with the driving piston; a nose body having a lower end with a nail discharge port; and a contact nose arranged to be protrusively urged toward a leading end of the nose body, the contact nose having an upper end and a leading end, including a cylindrical portion formed at its upper portion such that the cylindrical portion defines a circular cylindrical bore having a longitudinal axis and a substantially uniform cross section transverse to the longitudinal axis, the circular cylindrical bore extending from an interior of the contact nose to an upper end surface substantially transverse to the longitudinal axis of the upper end, the nose body being housed in the circular cylindrical bore such that the contact nose is held slidably along the nail discharge port of the nose body, wherein the contact nose includes a leading end discharge port for guiding a nail driven from the leading end discharge port toward a work, and the leading end discharge port includes a guide portion longer than the nail.
