ABSTRACT:
A successive screw feeder driver, including a motor housing accommodating an electric motor and a transmission mechanism and formed with a handle, a screw chain magazine holding a continuous screw chain having a great number of screws attached at uniform intervals to a connecting strip by means of an easily breakable filament, a screw drive mechanism for driving said screws, and a screw feed mechanism for feeding said screws one after another to a predetermined driving position. The transmission is mounted between the motor and handle. The screw driving mechanism is projected from the front end of the motor housing by a predetermined length in a direction parallel with the motor. The screw feed mechanism includes a feeder block located in front of the screw driving mechanism for holding in position a screw chain withdrawn from the screw chain magazine, a support member urged to support the feeder block normally in a position projected from the motor housing by a predetermined length and retractable into the motor housing at the time of screw driving operation, and a screw advance mechanism for advancing the screws of the screw chain successively in relation with back and forth reciprocating movement of the feeder block.
