Abstract
A screw feeding device in a continuous screw driving tool includes a casing mounted on a tool body of the continuous screw driving tool. A feeder box is reciprocally movable within the casing, so that a screw carrying belt is fed by a distance corresponding to one pitch of screws carried thereon as the feeder box is reciprocally moved by one stroke. A stopper base is mounted on the feeder box, and a mounting mechanism is provided for mounting the stopper base on the feeder box, so that the stopper base can be changed in its position relative to the feeder box. The mounting mechanism includes a plurality of lock holes and a lock member. The lock holes are formed on one of the stopper base and the feeder box and spaced from each other by a predetermined distance in a driving direction of a screw. The lock member has a lock protrusion engageable with any of the lock holes and is held in position in the screw driving direction relative to the other of the stopper base and the feeder box.
