CONSTITUTION:A hexagonal bar spanner turner 1 is a hexagonal cylindrical body, and it is provided with two sectional-form hexagonal through holes along both vertical and horizontal shafts. These through holes may be the same diameter and/or different ones. A hexagonal bar spanner 6 is inserted into either of these through holes. In this state, a mouth 8a of a general spanner 8 is applied to the hexagonal bar spanner turner 1, and this spanner 8 is turned round as specified, whereby the hexagonal bar spanner 6 is rotated with strong torque, so that a holed bolt 7 can be tightened to the full.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hexagonal bar wrench suitable for turning a hexagonal bar spanner (hexagonal wrench).

[0002]

2. Description of the Related Art A conventional hexagonal bar wrench 6 is shown in FIG. 6, which is generally L-shaped having a major axis 6a and a minor axis 6b. A conventional example of use is shown in the drawing, in which a hexagonal wrench is inserted into the bolt 7 with a hole in the device 9, and the long shaft 6a portion or the short shaft 6b portion is gripped and tightened.

[0003]

However, even if the hexagonal wrench is tightened directly by hand, sufficient torque cannot be obtained. Further, if the obstacle 10 or the like exists near the device 9, there is a risk that the hand may come into contact with the obstacle, which may hinder tightening.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to improve the usability and tighten safely when tightening a bolt using a hexagonal spanner. It is to provide a hexagonal wrench driver that can be tightened with a sufficiently strong torque.

[0005]

In order to achieve the above object, the hexagonal spanner driver according to claim 1 has a through hole having a hexagonal cross-section into which the hexagonal spanner is inserted along the vertical axis and the horizontal axis. It is characterized in that it is a hexagonal prism body provided by.

The hexagonal bar wrench driver according to a second aspect of the present invention is characterized in that a dodecagonal surface is formed on a part of the side surface of the hexagonal bar wrench driver.

Further, in order to achieve the above object, the hexagonal wrench driver according to a third aspect of the present invention is characterized in that the through holes provided along the vertical axis and the horizontal axis have different diameters.

[0008]

The hexagonal wrench driver of the present invention has a through hole having a hexagonal cross section, and the hexagonal spanner is inserted into this through hole. On the other hand, this hexagonal bar wrench has a hexagonal column shape, and the hexagonal bar wrench can be rotated with a strong torque by holding the hexagonal bar wrench with a wrench or the like with the hex bar wrench inserted.

In addition, since the hexagonal bar wrench of the present invention has a dodecagonal surface formed on a part of its side surface, the hexagonal bar wrench can be rotated by using a ratchet wrench or a box wrench.

Further, the hexagonal bar wrench of the present invention can accommodate different hexagonal bar spanners by having through holes having different diameters.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the hexagonal wrench driver of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a hexagonal wrench driver according to this embodiment. The hexagonal bar wrench driver 1 is a hexagonal columnar body, and is provided with through holes 2 and 3 having a hexagonal sectional shape along the vertical axis and the horizontal axis. Although the through holes 2 and 3 have the same diameter in this embodiment, they may have different diameters. The hexagonal spanner 6 is inserted into either of the through holes 2 and 3. In FIG. 1, a through hole 2 is provided along the vertical axis.
The state where the long shaft 6a of the hexagonal spanner 6 is inserted is shown in FIG. FIG. 2 shows a cross-sectional view of the hexagonal key wrench driver 1 of the present embodiment. FIG. 2 (a) is a vertical cross-sectional view and FIG. 2 (b).
FIG.

FIG. 3 shows a usage state of the hexagonal wrench key 1 of the present embodiment. In FIG. 3A, the long shaft 6a of the hexagonal spanner 6 is inserted into the bolt 7 with a hole, and the hexagonal spanner driver 1 is inserted into the long shaft 6a of the hexagonal spanner 6. In this state, as shown in Fig. 5, turn the hexagonal spanner 1
It is possible to turn the hexagonal spanner 6 with a strong torque by hooking the mouth 8a of the general spanner 8 on and to turn the spanner 8 to tighten the bolt 7 with a hole.

Further, in FIG. 3B, the long shaft 6a of the hexagonal bar wrench 6 is inserted into the bolt 7 with a hole, and the hexagonal bar spanner 6 is also inserted.
The hexagonal key wrench driver 1 is inserted into the short shaft 6b of the. In this state, the hexagon bar spanner 6 can be turned by turning the hexagon bar spanner turn 1 with the spanner 8. In this case, the hexagonal spanner 6 can be rotated without attaching the hexagonal spanner driver 1 to the long shaft 6a, so that the holed bolt 7 should be securely tightened even when there is a depth or an obstacle. You can

3 (c) and 3 (d) show an example in which the short shaft 6b of the hexagonal bar wrench 6 is inserted into the bolt 7 with a hole, and FIG. 3 (c) shows the hexagonal bar wrench driver 1. When inserting into the long shaft 6a, the hexagonal bar wrench driver 1 is shown in FIG.
This is the case of inserting into b.

In this embodiment, the side surface of the hexagonal bar wrench driver 1 is a hexagonal surface, but it is also possible to form a dodecagonal surface on a part of the side surface so that a ratchet wrench or a box wrench can be used. Is. An example of this case is shown in FIG. 4, and a dodecagonal surface 5 is formed on a part of the side surface 4. By using a dodecagonal surface, it is possible to more reliably turn the hexagonal rod turning 1 with a wrench as compared with the case of a hexagonal surface.

[0017]

As described above, according to the hexagonal wrench driver of the present invention, when the bolt is tightened by using the hexagonal wrench, the usability is improved and the bolt can be safely tightened and is sufficiently strong. Can be tightened with torque.
