Continuous screw driving tool

摘要

A continuous screw driving tool includes a body having a rotatably spindle for mounting a driver bit thereon. A feeder box having a screw feeding device for feeding a screw carrying belt is movable relative to a case which is fixed to the body. A stopper base is adapted to be mounted on the feeder box for abutment on a work into which a screw is to be driven. A first and second stopper mechanisms are provided for limiting a first stroke of the stopper base in a direction to extend outwardly from the case and a second stroke end of the stopper base in the opposite direction, respectively. The second stopper mechanism includes a first stopper member on the side of the body and a second stopper member on the side of the stopper base for abutment on the first stopper member. The second stopper member is movable with the stopper base as the stopper base is moved toward the second stroke end. The feeder box is adapted to selectively mount any one of plural kinds of the stopper bases each suited for a group of screws having different lengths. A stroke changing mechanism is provided for changing the position of the second stroke end in accordance with the change of the stopper base.
