However, there are several standards for F-type connectors and F-type plugs, and some have different nut sizes. Specifically, for example, nuts often used for indoor F-type connectors are 11 mm, and nuts often used for outdoor F-type connectors are 12 mm. In a field where multiple standards exist, it is necessary to prepare two spanners with diameters that match each nut.

There are also double-ended spanners that have openings with different diameters at both ends of the grip. However, when tightening and releasing different nuts, it is necessary to switch the double-ended spanner to the opposite side.

Furthermore, when connecting the coaxial cable from the antenna device to the F-type plug provided on the wall, it is necessary to remove the decorative panel that covers the F-type plug on the wall. Therefore, in addition to preparing two spanners with diameters that match the nuts, a tool for removing the decorative panel was also required. In addition, when working, it was necessary to select and hold two spanners that matched the nut, and to switch to a tool for removing the decorative panel, making the work extremely complicated.

In view of these circumstances, the present invention aims to provide a double-headed wrench that can tighten and release nuts of different diameters without the need to change tools, and can also remove decorative panels. be.

In order to achieve the above-mentioned object of the present invention, the double-headed wrench according to the present invention includes a grip portion in the shape of a long and thin plate, and is provided at one end in the longitudinal direction of the grip portion, and A double-headed mouth extending bent at a predetermined angle, having a first mouth and a second mouth disposed in the same plane as the first mouth and having a diameter different from that of the first mouth. It is provided with a double-headed opening portion and a thin plate-shaped spatula portion provided at the other end in the longitudinal direction of the grip portion and used for removing the decorative panel for the wall-side terminal.

Here, in the double-headed mouth part, the first mouth part and the second mouth part each have a U-shaped opening, and the openings face in a Y-shaped direction away from the longitudinal direction of the grip part. That's fine.

Further, the spatula portion may extend while being bent at a predetermined angle with respect to the plate-like surface of the grip portion.

Further, the spatula portion may be narrower than the width of the grip portion.

Furthermore, it may be provided with a protective tube that covers the spatula part when not in use.

The double-headed spanner of the present invention has the advantage that nuts of different diameters can be tightened and unlocked without the need to change tools, and decorative panels can also be removed.

FIG. 1 is a schematic diagram for explaining the double-headed spanner of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described along with illustrated examples. FIG. 1 is a schematic diagram for explaining a double-headed spanner according to the present invention, with FIG. 1(a) being a front view thereof and FIG. 1(b) being a side view thereof. As shown in the figure, the double-head spanner of the present invention is mainly composed of a grip section 10, a double-head opening section 20, and a spatula section 30.

The grip portion 10 is an elongated plate-shaped portion. As illustrated, the grip portion 10 is mainly composed of an elongated plate-like surface 11. The grip portion 10 may be made of a steel material such as chromium molybdenum steel or chromium vanadium steel. Note that the grip portion 10 may be integrally molded with a double-headed mouth portion 20 and a spatula portion 30, which will be described later. If the double-headed spanner of the present invention is a spanner for tightening and releasing a nut for an F-type connector, it does not require that much tightening force. Therefore, the grip portion 10 only needs to be long enough to be gripped with one hand. Specifically, the length of the plate-like surface 11 may be about 40 mm to 50 mm. Further, the width of the plate-like surface 11 may be about 16 mm, and the thickness may be about 2 mm. It is sufficient if the entire length including the double-headed mouth part 20 and the spatula part 30, which will be described later, is about 100 mm. Note that the present invention is not limited to specific dimensions, and can be changed as appropriate.

The double-headed mouth portion 20 is provided at one end of the grip portion 10 in the longitudinal direction. Further, the double-headed mouth portion 20 has a first mouth portion 21 and a second mouth portion 22. The first mouth part 21 and the second mouth part 22 are both arranged in the same plane and have different diameters. In the illustrated example, the first opening 21 has a diameter of 11 mm, and the second opening 22 has a diameter of 12 mm. This is because 11 mm nuts are often used for indoor F-type connectors, and 12 mm nuts are often used for outdoor F-type connectors. However, the present invention is not limited to this, and as long as the diameters of the first mouth portion 21 and the second mouth portion 22 are different, it is of course possible to use other diameters.

The first opening 21 and the second opening 22 each have a U-shaped opening. This opening has the shape for a hexagonal nut. However, the present invention is not limited to this, and any shape suitable for the nut to be fastened and released may be used. Further, this opening faces in a direction away from the longitudinal direction of the grip portion 10 in a Y-shape. That is, the openings of the first opening 21 and the second opening 22 are arranged to face outward.

As can be seen from FIG. 1(b), the double-headed mouth portion 20 extends while being bent at a predetermined angle with respect to the plate-like surface 11 of the grip portion 10. That is, the double-headed mouth portion 20 is bent from the grip portion 10 and extends so as to be lifted from the plate-like surface 11 of the grip portion 10. When tightening and releasing the nut part of the coaxial cable with respect to the F-type plug installed on the wall, a double-headed wrench is used along the wall, so the hand holding the grip part 10 does not touch the wall. It is fine as long as it is bent to the extent that it does not get in the way. Specifically, for example, the bending angle of the double-headed mouth portion 20 may be about 30 degrees.

Further, a spatula portion 30 is provided at the other end of the grip portion 10 in the longitudinal direction. That is, the spatula part 30 is provided at the end of the grip part 10 opposite to the end where the double-headed mouth part 20 is provided. The spatula part 30 has a thin plate shape and is used to remove the decorative panel for the wall side terminal. The spatula part 30 may be narrower than the width of the grip part 10. In the illustrated example, the spatula portion 30 is thinned in two steps, but the present invention is not limited to this, and may be thinned in one step. The spatula part 30 has a thin and sharp tip so that it can be inserted into a gap in the decorative panel. That is, as shown in the illustrated example, not only the width but also the thickness is reduced. Therefore, a protective tube 31 may be provided to cover the spatula part 30 when not in use. By protecting the tip with the protective tube 31, it is possible to prevent an operator from getting injured when taking out a double-headed wrench stored in a pocket.

Although the spatula portion 30 in the illustrated example extends straight from the plate-like surface 11 of the grip portion 10, the present invention is not limited thereto. That is, like the double-headed mouth part 20, the spatula part 30 may be bent and extended at a predetermined angle with respect to the plate-like surface 11 of the grip part 10. The bending direction may be the same side as the side where the double-headed mouth part 20 is bent, or may be bent to the opposite side.

The double-headed spanner of the present invention constructed in this way has three functions, namely, a spanner of two sizes and a decorative panel removal tool. The double-headed wrench of the present invention, which integrates three functions, is useful when working with nuts of different diameters when tightening and releasing the nut portion of a coaxial cable with respect to an F-type connector installed on a wall. However, since it is a double-headed wrench, there is no need to change tools. Since the same tool is used to remove the decorative panel, there is no need to prepare a separate tool. Therefore, the work does not become complicated. Furthermore, since the double-headed mouth part and the spatula part are respectively provided at both ends of the grip part, they do not get in the way of each other, and workability similar to that of a conventional dedicated spanner or a dedicated decorative panel removal tool can be achieved.

Note that the double-headed spanner of the present invention is not limited to the illustrated example described above, and it goes without saying that various changes may be made without departing from the gist of the present invention.
