<p>A tubular arrangement (5) the front end of which defines a fastener outlet is extendably and contractably mounted to a fastener driver body (1). A drive bit (2) is mounted within the tubular arrangement. A fastener feeder (7) is mounted to the tubular arrangement and contains a pair of fastener guiding plates (31, 32) opposite each other with a predetermined distance sufficient to pass a strapped fastener assembly (6). One of the fastener guiding plates (31) defines a fastener passage opening (46) for feeding a fastener (10B) into the tubular arrangement (5E) through a fastener feed hole (37) defined in the side wall of the tubular arrangement. A fastener feed mechanism (50) with a feed roller (49) intermittently engaging and advancing the strap (6) is provided. A fastener separation element (77) of a fastener separation mechanism (80) passes into and out of the fastener passage clearance through, presses the fastener and separates it from the strap (6) when the fastener separation element extends out of the fastener passage clearance, to feed the separated fastener (10A) into the tubular arrangement. First (8) and second (9) actuators both mounted to the fastener driver body actuate the respective fastener feed and fastener separation mechanisms.</p> |
