DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screw guide for an impact driver.

[0002]

2. Description of the Related Art A conventional example of screw tightening by an impact driver will be described with reference to FIG. FIG.
FIG. 4 is a side view illustrating fastening to a screw by a conventional impact driver.

In FIG. 5, a screw 21 is connected to a member 2 such as wood.
The screw 21 is temporarily fixed to the member 22 by disposing the screw 21 at a point perpendicular to the surface 2 and making the tip of the screw 21 bite into the member 22.

Then, the impact driver 23 is
The screw 21 is tightened by being arranged on the first head 21a and driven.

[0005]

When the screw is obliquely tightened with respect to a member using the above-mentioned impact driver, the tip of the screw does not bite into the member. Is difficult to tighten. That is, since the impact driver tightens the screw by an impact, there is a possibility that the position of the screw is shifted if the position of the screw is not fixed first.

[0006]

According to the present invention, there is provided a semicircular groove having a side surface formed at an acute angle with respect to a member for tightening a screw, on which the body of the screw can be disposed. A screw tightening guide for an impact driver, comprising a formed mounting portion.

[0007] Alternatively, a hole is formed obliquely penetrating between a surface into which the screw is inserted and a surface in contact with the member to which the screw is to be fastened. A screw tightening guide for an impact driver, wherein the screw body is formed by a small hole through which a body of the screw passes.

[0008]

When the screw is screwed obliquely to the surface of the member, the screw has a side surface formed at an angle, and a screw tightening guide having a groove formed on the side surface is used. By tightening, you can easily tighten the screw,
The positioning of the screw fastening portion can be easily performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of screw tightening by an impact driver using a screw tightening guide according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a screw tightening guide according to the present invention. FIG. 2 is a diagram illustrating screw tightening using the screw tightening guide of FIG.
FIG. 3 is a side sectional view of a screw tightening guide according to another embodiment of the present invention. FIG. 4 is a side sectional view after a screw is fastened to a member using the screw fastening guide of FIG. 3.

In FIG. 1 and FIG. 2, the screw tightening guide 1 of the impact driver is
And a handle portion 2 for pressing the screw tightening guide 1 against the member, and a mounting portion 4 for mounting the screw 3.

A protrusion 2a having a sharp tip is provided on the bottom surface of the handle portion 2. The protrusion 2a is attached to the surface of the member 5 to be screwed tightly.
Into the member 5, and the screw tightening guide 1 can be fixed to the member 5.

The side surface 6 of the mounting portion 4 is cut obliquely so that the angle between the side surface 6 of the mounting portion 4 and the surface of the member 5 becomes an acute angle. The side surface 6 is provided with a semicircular groove 6 a perpendicular to the surface of the member 5.
Further, a plurality of grooves 6 a each of which also matches the diameter of the screw 3 may be provided on the side surface 6.

In FIG. 2, a screw tightening guide 1 is pressed against a member 5 and a projection 2 provided on the screw tightening guide 1 is provided.
The screw tightening guide 1 is fixed to the member 5 by biting a. At this time, the mounting portion 4 is
And fix it upside down. Then, the screw 3 is mounted in the groove 6 a provided on the side surface 6 of the mounting section 4.

The screw 6 can be easily and accurately tightened by tightening the screw 6 while pressing the body 6b of the screw 6 against the groove 5a with the impact driver 7.

In FIGS. 3 and 4, the screw tightening guide 11 is formed in a rectangular shape, penetrates obliquely from an arbitrary surface, and is provided with a hole 12 for inserting a screw 13. .

The hole 12 is formed by a large hole 12a having a large diameter and a small hole 12b having a smaller diameter than the large hole 12a. The small hole 12b is formed slightly larger than the diameter of the body 13b of the screw 13, and the large hole 12a is formed slightly larger than the head 13a of the screw 13. After tightening the screw 13, the head of the screw 13 is tightened. 13a is a screw tightening guide 11
It is designed to be stored inside. A projection 11a having a sharp tip is provided on the surface provided with the small hole 12b.

The screw tightening guide 11 is connected to the member 14.
, And the protrusion 11a is cut into the member 14 and fixed. Then, the screw 13 is inserted into the hole 12, and the screw 13 is tightened with an impact driver. After tightening, the head 13a of the screw 13 is stored in the large hole 12a.

When the screw 13 is attached to the member 14 at an angle, the head 13a of the screw 13 is attached to the member 14 at an angle, which is not good in appearance.

Therefore, if the screw tightening guide 11 is used, even if the screw 13 is tightened diagonally, the head 13a of the screw 13 after being tightened is hidden in the screw tightening guide 11, and the appearance is impaired. Never.

[0020]

According to the present invention, when tightening a screw obliquely, it is possible to easily and accurately determine a screw tightening position and tighten the screw. Furthermore, the appearance of the screw head after the screw is tightened can be improved.
