Claims

[Claims for Utility Model Registration] A method of driving a fastener fed into a passageway of a nose extending from a main body by a driving member driven by a piston-cylinder device of the main body; A fastening tool provided with a pair of chuck members on the distal end side, which are normally biased to close to hold the fastening tool, and are opened by the fastening tool when the fastening tool is pushed out by the driving member. In the driving machine, a blocking member is provided on a side surface of the chuck member and is normally biased to engage with the distal end side of the chuck member to prevent it from opening. A fastening tool driving machine characterized in that the fastening tool of the member is pivoted so as to be disengaged from the chuck member by the driving operation of the fastening tool of the member.
