POWER TOOL FOR METAL PIERCING FASTENERS

摘要

A power tool for installing metal piercing fasteners being characterized by a body bent at one end to form a crown portion and having at least one side guide rail and at least one integral tine under the crown portion, the integral tine being deformed about its longitudinal axis to cause at least one portion of the tine to protrude outwardly from the body of the fastener comprises a fastener guide body including at least one guide channel adapted to accommodate the side guide rail of the metal piercing fastener. The guide channel defines a linear drive path for the metal piercing fastener. The power tool also comprises a fastener driver body including at least one outwardly protruding side spline adapted to conform approximately to the outer contours of the side guide rail of the metal piercing fastener and to slide within the trajectory channel, and a fastener driver tip for forcibly impacting the crown portion of the metal piercing fastener. The fastener driver tip is coupled to one end of the fastener driver body and adapted to follow approximately the outer configuration of the fastener driver.
