Field of the Invention The present invention protects the tip of a screw tightening machine in which the screw head does not project onto the surface of the face material which is the material to be screwed in when the screw is driven obliquely into the material to be screwed. Regarding the cover.

Description of the Related Art When a face material such as a gypsum board is fixed to a steel plate by a screw tightener with a screw, a driver relatively protruding from the main body of the screw tightener by pressing the nose part of the tip of the screw tightener against the gypsum board. Although the bit is screwed in while extruding the screw supplied to the nose part, the tip of the nose part is made of urethane at the part that contacts the gypsum board so that the surface of the gypsum board is not scratched or marked when pressed. A soft protective cover made of resin or the like is attached.

いう追加施工が必要となり、作業が煩雑になる。By the way, the head of the face material screw is formed to have a large diameter so as not to easily come off from the gypsum board. Further, the driver bit of the screw tightener is dimensioned such that the head surface of the screw fits flush with the face material when pressed vertically against the face material. Therefore, when using the tool at an angle,
As shown in FIG. 5, a part of the protective cover 20 hits the surface of the face material 21, and the head diameter of the screw 22 is large, so that the screwing tends to be insufficient, and one side of the head 22a is a surface. Problems such as sinking from the surface of the material 21 and protruding from the surface of the facing material 21 on the opposite side are likely to occur. In the actual construction, the screw is frequently screwed diagonally, and in many cases, a cloth (cloth material) is stretched at the end on the face material 21, and the head 22a of the screw projects from the surface of the face material 21. As a result, the work is complicated because additional work is required to tighten the screw 22.

Is a protective cover that is attached to the tip of the, and the tip is formed in a spherical shape, and the outer surface of which is formed with a plurality of grooves to prevent slipping so as to form a concentric circle centered on the top of the tip. It is characterized by

締め作業などの追加施工をする必要がない。According to the present invention, when the screw is screwed into the face material in an oblique direction, the screw tightening machine is tilted, so that the portion of the protective cover which is inclined with respect to the center is pressed against the face material. . However, in this case, since the tip of the protective cover is formed into a spherical shape, the tip surface of the protective cover is not so far apart from the surface of the face material even if the screw tightener is tilted.
Therefore, the screw is screwed deep enough so that its head does not protrude from the surface of the face material. Therefore, it is not necessary to perform additional construction such as retightening work.

Since there is no screw, reliable screwing work can always be performed.

As shown in FIGS. 3 (a), 3 (b), 3 (c) and FIG. 4, a hole 6 through which the screw and the driver bit 3 pass is formed at the center of the protective cover 5. Further, the rear surface of the protective cover 5 is opened, and a concave portion 7 to be fitted into the tip portion 2b of the nose portion 2 is formed inside. An opening groove 8 continuous with the hole 6 is formed in the lower portion of the protective cover 5. An opening groove 9 is also formed on the base end side of the upper portion of the protective cover 5.

護カバー５の穴６に臨むようにセットされる。The connecting screw 4 is formed by connecting a large number of screws 4b to a connecting band 4a made of synthetic resin or the like. The connecting screw 4 is attached to the insertion groove 2a of the nose portion 2 so as to come out from the bottom to the top. At this time, the screw 4b at the tip is located on the extension of the central axis of the driver bit 3 of the screw tightener main body 1, and is set so as to face the hole 6 of the protective cover 5.

Further, when there is a screwing failure or the like, the screw 4b at the tip is discharged to the outside through the opening groove 9 on the upper side of the protective cover 5.

When the tip of the protective cover 5 of the nose portion 2 is pressed against the face material 13a and the nose portion 2 is pushed in, the driver bit 3 of the screw tightener main body 1 relatively moves forward and moves forward to remove the screw 4b in the nose portion 2. Push it forward. The screw 4b is pushed out while rotating and is screwed into the face material 13a. After the screw tightening is completed, when the screw tightening machine is separated from the face material 13a, the nose portion 2 separates from the screw tightening machine and the driver bit 3 retracts. Then, due to the relative movement of the nose portion 2, the screw feeding mechanism operates and the connecting screw 4 is fed.

要がない。When the screws are screwed into the face material 13 in an oblique direction, the screwing operation is performed in the same manner. In this case, the screw tightener is tilted as shown in FIG. 2, so that a portion of the protective cover 5 which is biased to the tilted side is pressed against the face material 13. However, in this case, since the tip of the protective cover 5 is formed into a spherical shape, the tip end surface of the protective cover 5 is not so far apart from the surface of the face material 13 even if the screw tightener is tilted. Therefore, as shown in the figure, the screw 4b is screwed deep enough so that the head 12 thereof does not protrude from the surface of the face material 13. Therefore, it is not necessary to perform the tightening work.

ねじ込み作業を行なうことができる。Further, since a slip stopper is formed on the outer surface of the protective cover 5, when the screw tightener is pressed obliquely against the face material 13, the protective cover 5 slips and the screwing position is displaced. Since there is no inconvenience, it is possible to always perform a reliable screwing operation.

層大きくなる。Moreover, since the side walls 11 on both sides of the anti-slip groove 10 are formed so as to be parallel to the axis of the protective cover 5, as shown in FIG.
Since the side wall 11 on one side hits the face material 13 at an acute angle, the resistance due to the edge increases and the anti-slip effect further increases.
