Abstract:
The present invention provides a screw feeding/fastening unit of a continuous screw fastening device which enables assuredly pulling screws out of a screw strip in tandem with a screw fastening operation even in case of using the screws each of which has, e.g., a flat shape below its head portion.
A screw feeding/fastening device of a continuous screw fastening device according to the present invention is a screw feeding/fastening unit 1 of a continuous screw fastening device which fastens screws 4, and it is configured to include a screw strip binding piece unbinding section 51 which supports a screw strip guide unit 2 to be rotatable in a direction orthogonal to a longitudinal direction of a bit by a shaft body 53 provided at a position before a feed case 22 in a feeder unit 21 and to be restorable to its original position by a spring 54, has on the screw strip guide unit a turning receiver 6 which abuts on a part of a slide frame and receives turning force at the time of a slide operation of the slide frame 31 toward the screw strip guide unit, and turns the screw strip guide unit together with the turning receiver around the shaft body as a spindle in a direction along which a tip side gets away from a screw at the fastening acting position to impart unbinding force to a screw strip binding piece 3a at the time of fastening the screw.
