Claims

[Scope of utility model registration request]

This is a screw tightening machine that continuously tightens connecting screws in which the shafts of the screws are inserted and held at regular intervals through a long synthetic resin connecting band, and is an adapter that is attached to the driver body that rotates the driver bit. a main body, a nose member supported by the adapter main body so as to be relatively movable in the axial direction of the driver bit, and a relative movement between the adapter main body and the nose member provided on the nose member and accompanying a screw tightening operation. and a connecting screw feeding mechanism that feeds the screws on the connecting band into the nose member at the initial stage of the operation, and a screw feeding mechanism that feeds the screws on the connecting band into the nose member at the tip of the screw driving opening of the nose member. A screw for a screw tightening machine for connecting screws, characterized in that a stopper is formed that engages with the tip of the shaft part and prevents the tip of the screw from moving forward in the screw supply direction from the screw driving opening. Posture holding device.
