Claims

[Scope of Claim for Utility Model Registration] (1) A sliding guide case is attached via a connecting member to the tip of the driver tool on which the driver bit is attached, and the sliding member is inserted into the sliding guide case via a spring. A sprocket that is slidably inserted in the vertical direction and meshes with the screw holding belt, a ratchet wheel that meshes with the sprocket, and a ratchet wheel that meshes with the sprocket are disposed on the sliding member, and the sliding member is slid against the return spring. When the screw is pushed into the guide case, the ratchet wheel rotates, and a sprocket that engages with the ratchet wheel moves the screw holding belt one screw distance, and the screw transferred below the driver bit can be driven by the driver bit. In the screw driving device, the sliding member in the sliding guide case is pushed back by a return spring, and the ratchet wheel returns to the standby state. In order to prevent rotation in the opposite direction, a spring-biased rotation operation lever whose one end abuts against the feed dog of the sprocket is attached to the sliding member, and the rotation operating lever appearing on the sliding surface of the sliding member is attached to the sliding member. A screw driving device characterized in that an operating portion on the other end side of the dynamic operating lever does not protrude from the sliding surface. (2) Attach a sliding guide case via a connecting member to the tip of the driver tool on which the driver bit is attached, and fit the sliding member into the sliding guide case via a return spring so that it can freely slide vertically. , the screw holding belt with screws embedded therein is loaded into the belt loading portion of the sliding member, and when the sliding member is pushed into the sliding guide case, the screw holding belt is transferred by one thread section, and In a screw driving device configured to drive a screw transferred below the bit into a member to be driven by the driver bit, a groove for sliding guide is formed vertically on the outer surface of the sliding member, and a groove is formed in the vertical direction on the outer surface of the sliding member. A convex portion that fits is provided protrudingly on the inner surface of the sliding guide case, a groove for regulating the sliding range is formed in the vertical direction except for the upper part on the outer surface of the sliding member, and a pin that fits into this groove is formed. A screw driving device characterized in that a screw is protruded from the inner surface of the sliding guide case.
