Claims

[Scope of utility model registration request]

Provided at the tip of an automatic screw tightening machine having a driver bit for screwing a screw supplied from a screw supply device onto a workpiece, and a suction pipe containing the driver bit and sucking the screw,
A catch unit of an automatic screw tightening machine that holds the screw, wherein a guide hole into which the suction pipe can be inserted and removed and a screw supply hole into which the screw from the screw supply device is guided are opened adjacent to each other on the same plane; A slider slidably attached to the main body, a moving means for reciprocating the slider, a slide claw provided on the slider for reciprocating between the guide hole and the screw supply hole, and the screw supply hole. a fixed claw provided at a position facing the slide claw across the guide hole, and a guide hole claw provided at a position aligned with the fixed claw and opposite the slide claw that has slid across the guide hole. The screw is supplied when the slide claw and fixed claw are facing each other, and the slide claw moves to the position facing the guide hole claw while holding the screw, and when the screw is attracted, the screw is fed. A catch unit for an automatic screw tightening machine characterized in that the claw returns to a position facing the fixed claw.
