Claims

[Scope of Claim for Utility Model Registration] A screw tightening machine that continuously tightens connecting screws in which screw shafts are inserted and held at regular intervals through a long synthetic resin connecting band, which rotates a driver bit. an adapter body attached to the driver body to be driven; a nose member supported by the adapter body so as to be relatively movable in the axial direction of the driver bit; a connecting band supply mechanism for supplying the connecting band to the adapter body, a magazine having a semi-disc-shaped portion on the opposite side of the screw driving direction is attached to the adapter body, and connecting screws are installed inside the magazine along the circumferential side thereof. The connecting screw guide path for guiding is formed in an arc shape,
The connecting screw guide path is composed of a wide connecting band guide portion on the outside and a narrow screw shaft guide portion on the inside, and the end face of the screw shaft guide portion is connected to the connecting screw supplied from the opening on the other end side. Formed as an inclined guide surface that guides the screw shaft portion, and connected to the shoulder portion connecting the connecting band guide portion and the screw shaft guide portion from the inclined guide surface that guides the screw shaft portion to the screw shaft guide portion. A stepped portion is formed on the screw supply side to accommodate the side edge of the connecting band guided along the inclined guide surface, and the connecting screw feeding side end of the stepped portion is formed to engage with the side edge of the connecting band. A connecting band guide device for a screw tightening machine for connecting screws, characterized in that a guiding wall surface is formed to guide the side edge to the connecting band guide portion as the joining connecting band advances in the supply direction.
