<p>An automatic screw feed-in apparatus comprises a body constituted by a frame with a cover secured thereon, inside which a substantially circular interior space is formed to receive a pair of feeding wheels rotatable about a central axis thereof, which feeding wheels are in detent engagement with a driving wheel which is rotatable about the central axis with a follower pin extending therefrom through an arcuated slot formed on the cover, concentric with the central axis. An inlet and an outlet are provided on the body with a channel connecting therebetween to conduct an elongated strip having screws equally spaced thereon into the interior space of the body by the driving engagement thereof with the feeding wheels so as to move the screws to a ready-to-be-tightened position. A casing which houses the body in a biasing and movable manner relative to the body has a slot comprising an inclined section to partially receive the follower pin therein so that when the casing is moved toward the body, the driving wheel is caused to move the follower pin from the lower dead point to the upper dead point while the feeding wheels remain un-moved and when the casing is released, the follower pin moves from the upper dead point to the lower dead point to drive the driving wheel which in turn moves the feeding wheels by the detent engagement therebetween to advance the screw strip. <IMAGE></p> |
