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 and a ratchet arm is reciprocally pivotable as the feeder box is reciprocally moved. An intermediate gear is connected to the ratchet arm by mechanism of a one-way clutch and is rotatable by a predetermined angle as the ratchet arm is pivoted in one direction. A ratchet wheel has feeding claws engageable with a screw carrying belt and has a gear part engaged with the intermediate gear, so that the ratchet wheel is rotated in a feeding direction as the intermediate gear is rotated and that the screw carrying belt is fed by a distance of one pitch of screws carried by the screw carrying belt for each reciprocal movement of the feeder box.
