Description

【考案の詳細な説明】本考案は、従来の種々の屈折軸に比べて構造が簡単で加
工工数が少な、く伸長・屈折操作も容易で屈折状態の確
実性が高い屈折軸の提供を目的としている。[Detailed description of the invention] The purpose of this invention is to provide a refracting shaft that has a simpler structure, requires fewer processing steps, is easier to extend and bend, and has a higher degree of certainty in the refracted state than various conventional refracting shafts. It is said that

以下、本考案の詳細を図面の実施例に基いて説明すると

Ａ、Ｂに対して４５度に傾斜した斜面３，４を形成し、
該各一端部１ａ、２ａには、夫々の斜面３，４の中心Ｃ
１Ｃを通り該斜面３゜・４に対し９０度をなすように貫
通したビン孔５゜・６を穿設し、前記軸本体１と屈折片

自在となるように該ビン孔５，６にピン７を嵌着してな
る構造である。Hereinafter, the details of the present invention will be explained based on the embodiments shown in the drawings. Forming slopes 3 and 4 inclined at 45 degrees with respect to lines A and B,
Each one end portion 1a, 2a has a center C of each slope 3, 4.
Pin holes 5° and 6 passing through 1C and forming 90 degrees with respect to the slopes 3° and 4 are bored, so that the shaft body 1 and the bending piece 2 cannot be separated from each other, and the pin hole 5 , 6 has a structure in which pins 7 are fitted into the bottle holes 5 and 6 so as to be rotatable.

なお、１ｂは軸本体１の他端部に形成した円形頭部であ
る。Note that 1b is a circular head formed at the other end of the shaft body 1.

また、第１図の屈折状態から第３図の伸長状態にするに
は、屈折片２をピン７の回ジに１８０度回紙回転ればよ
く、この伸長状態から更に１８０度回紙回転るとまた元
の屈折状態へ戻る。Furthermore, in order to change from the bent state shown in FIG. 1 to the extended state shown in FIG. and returns to the original refraction state.

以上のように、本考案の屈折軸は、軸本体と屈折片との
４５度の斜面の中心をピンで回転自在に連結したもので
あるから、構造が簡単で、加工工数が少なく、また伸長
−屈折操作も容易であシ、しかも不測に屈折片が１８０
度だけ回転することはまずないので、屈折状態の確実性
は高い等、多くの効果が期待できる。As described above, the refracting shaft of the present invention has a simple structure, requires less processing steps, and is easy to extend, since the center of the 45-degree slope of the shaft body and refracting piece is rotatably connected with a pin. - Refraction operation is easy, and the refraction piece is unexpectedly 180 mm.
Since it is unlikely to rotate by a single degree, many effects can be expected, such as a high degree of certainty in the refraction state.
