A ratchet wheel 27 that meshes with 6 is provided.
The ratchet wheel 27 has a feed pin 28 in which the sliding member 24 is pushed into the case 22 and projects from the ratchet wheel 27.
However, since the sprocket 26 is rotated when passing through the inclined portion 29A of the slit 29 cut out in the case 22, this operation causes the screw holding belt 25 to be transferred by one screw section. At this time, if the sliding member 24 is further pushed into the case 22, the screw screw 25A can be driven into the driven member 5 by the driver bit 30 driven by the electric screwdriver tool 20. When the sliding member 24 is returned by the return spring 23, only the ratchet wheel 27 idles and returns to the original state.

FIG. 1 shows an embodiment of a connecting screw screw according to the present invention. In this figure, a screw thread 2 is vertically formed on the screw screw 1. A dish portion 3 into which a driver bit of an electric screwdriver tool is fitted is formed at the upper end head portion. A first cutout groove 4 is formed in the vertical direction at the tip of the screw screw, and a part of the thread 2 is cut off by the cutout groove 4. Since the notch groove 4 is formed at the tip of the screw screw in this way, when the screw is driven into the driven member 5 by the screw driving device, the notch groove 4 is recessed as shown in FIG. Driving member 5
Since it bites into, the screw becomes stronger against the pulling force, and the screw is hard to come off from the driven member 5.

らくなる。Next, the screw screw 6 of another embodiment shown in FIGS. 3 and 4 will be described. In this embodiment, a first notch groove 4 is formed at the tip of the screw, and another second notch groove 7 is formed at a position above the notch groove 4 in the plurality of screw threads 2. It is straddled vertically. By forming the two notched recessed grooves 4 and 7 on the screw screw in this way, the screw driven into the driven member 5 is inserted into the notched recessed grooves 4 and 7.
Since it cuts in, it becomes stronger against pulling force and it becomes difficult to pull out.

Is formed, and a threadless portion 9 having no thread is provided at an upper position of the threaded portion. By providing the non-threaded portion 9 in this way, the screw driven into the driven member 5 bites the driven member 5 into the cutout grooves 4 and 7, and
The driven member 5 also bites into the unthreaded portion 9 sandwiched between the upper and lower threads, and becomes stronger against the pulling force.

き抜き力に対してさらに強固になる。Next, a screw screw 10 according to another embodiment shown in FIGS. 7 and 8 will be described. In this embodiment, two notch grooves 4 are provided in the thread portion from the tip.
7 is formed, and a knurled concave-convex groove portion 11 is engraved in the vertical direction at the upper position of the thread engraved portion. By forming the knurled concave-convex groove portion 11 at the upper position of the screw screw in this way, the screw driven into the driven member 5 is knurled as the driven member 5 bites into the notched concave grooves 4 and 7. The driven member 5 also bites into the tooth profile of the concave-convex groove portion 11 and becomes stronger against the pull-out force.
