Abstract:
1. A method for inserting a fixing element into each of at least one predefined seat of a work piece, comprising: providing a first fixing element at a lower face of a nose piece in a position facing a first end of a drive rod, the first end of the drive rod being received in a drive channel of the nose piece; the drive rod receiving a downward drive force on a second end thereof; the drive force moving the drive rod from an initial upper position, through a first intermediate position, and toward a lower position; the drive rod exerting a force on an actuator while moving through the first intermediate position; the actuator exerting a force on at least one finger, which is biased toward a side wall of the nose piece; and thereby moving the finger from a closed position in which a lower portion of the finger is disposed under an outer portion of the flange of the first fixing element, to an open position in which the lower portion of the finger is moved away from under the outer portion of the flange of the first fixing element; and upon reaching the lower position, the downward drive force on the drive rod inserting the first fixing element into a first predefined seat of the work piece, wherein the actuator is a movable member accommodated in an opening penetrating through the side wall of the nose piece, the movable member having an inner end extending into the drive channel when the finger is in the closed position, and wherein when the drive rod moves through the first intermediate position, the drive rod causes the movable member to move the finger, which causes the lower portion of the finger to move away from under the outer portion of the flange of the first fixing element.
