Abstract:
A successive screw driving attachment in which a screw feed mechanism and a distal end screw guide are provided to a front part of a driver unit, and a coupling tube for connecting to an electric screwdriver via a coupling adapter is provided to a rear part of said driver unit,wherein said driver unit forms a guide tube into which a bit is inserted, an elastic member is mounted for pressing the screw feed mechanism forward so that it is slidable in a longitudinal direction of said guide tube, and a drive depth adjustment mechanism that adjusts a depth to which the screw is driven by said bit; said screw feed mechanism includes a screw feeder comprising a screw feed prong that sequentially feeds the screws on a screw rope, in which numerous screws are lined up and attached to a rope, to a driving position of said bit for interlock with the longitudinal sliding of said driver unit that accompanies the driving action produced by said bit in said distal end screw guide; said screw feeder is structured such that said screw feed prong instantly feeds the next screw to the driving position when said screw feed mechanism has been pushed back to the distal end; said distal end screw guide has a rope guide path for said screw rope, and has formed in it a screw feed hole for the reciprocal action of said screw feed prong; and wherein a bracket is attached to said coupling adapter and an arm having a grip is detachably attached to said bracket.
