Abstract
This invention provides a driver attachment for a collated screwstrip in which a slide body is slidable in a housing parallel a longitudinal axis about which drive shaft is rotatable. The slide body has a rear portion and a removable nose portion. The housing and rear portion of the slide body form an integral part effectively permanently assembled and including a screw feed activation mechanism coupled between the housing and rear portion and which translates relative sliding movement and positioning of the rear portion of the slide body relative the housing. The nose portion is removable from the rear portion for ease of replacement with other nose portions adapted for use with the same or different sized screwstrips and/or screws. The nose portion includes a channel to guide a collated screwstrip generally transversely to the longitudinal axis of the drive shaft.
The nose portion includes a guide mechanism to locate each successive screw advanced through the channel into axial alignment with the drive shaft for engagement therewith.
The nose portion also includes a screw feed advance mechanism to advance the screwstrip through the channel when activated by the screw feed activation mechanism. The screw feed advance mechanism readily uncouples from and couples with the screw feed activation mechanism on uncoupling and coupling of the nose portion with the rear portion.
The nose portion includes a guide mechanism to locate each successive screw advanced through the channel into axial alignment with the drive shaft for engagement therewith.
The nose portion also includes a screw feed advance mechanism to advance the screwstrip through the channel when activated by the screw feed activation mechanism. The screw feed advance mechanism readily uncouples from and couples with the screw feed activation mechanism on uncoupling and coupling of the nose portion with the rear portion.
