される。Rotate the nut tube 8 in the direction to open the opening introduction part, remove the nut tube 8 from the opening male screw part 6, and use the joint rotating part a to connect one U-shaped rod 1 to the other U-shaped rod. When the U-shaped rod 2 is rotated so that the U-shaped rods 2 and 2 are deviated from each other, the joint threaded portion 3
Since the joint male threaded portion 4 screwed into rotates, an opening is formed between the tip of the U-shaped rod 1 and the tip of the nut rg18.
この開口部から例えばワイヤーローブ10をU状杆1・
2で形成される環体内に嵌入し、一方のU状杆1と他方

る。At this time, the other U-shaped rod 2 is attached to the locking portion 7 against the nut cylinder 8.
is formed to prevent it from coming off, and the other U
Since the joint male thread part 4 of the joint thread part 2 is formed in a state that prevents it from coming off with respect to the joint thread part 3, by rotating the nut cylinder 8, one U-shape rod 1 and the other U-shape rod 1 are connected. 2 are definitely connected.
また、継合螺部3と継合雄螺子部4との間にがたつき防
止のクッション材若しくは発条5が介在されている為、
継合雄螺子部4は継合螺部3内でがたつかない。In addition, since a cushioning material or spring 5 is interposed between the joint thread part 3 and the joint male thread part 4 to prevent rattling,
The male joint thread part 4 does not wobble within the joint thread part 3.
次に請求項2記載の発明について説明する。Next, the invention according to claim 2 will be explained.
請求項2記載の発明は、他方のU状杆2の継合雄螺子部
4を可能な限り径大にし、より強度を発揮させた発明で
ある。The invention according to claim 2 is an invention in which the diameter of the connecting male screw portion 4 of the other U-shaped rod 2 is made as large as possible to exhibit greater strength.
請求項1記載の実施例において、継合雄螺子部4の端部
に発条5を嵌入する凹所11を形成せしめるような場合
継合雄螺子部4か細いと強度が弱くなるからできるだけ
継合雄螺子部4の径を大きく形成しなければならない。In the embodiment according to claim 1, when the recess 11 into which the spring 5 is inserted is formed at the end of the male joint thread 4, the strength will be weakened if the male joint thread 4 is thin. The diameter of the threaded portion 4 must be made large.
一方、継合雄螺子部4の径を大きくすると、ナツト筒8
の係止鍔部9の貫通孔13にU状杆2を嵌挿することが
できなくなる。On the other hand, if the diameter of the joint male screw part 4 is increased, the nut cylinder 8
The U-shaped rod 2 cannot be inserted into the through hole 13 of the locking collar 9.
そこで請求項2記載の発明は、ナツト筒8の係止鍔部9
に雌螺子9°を設け、継合雄螺子部4の雄螺子4°をナ

螺子部4を螺入ではなく、単に通過せしめる場合に比し
、ネジの高さだけ径大になり(第5図参照)、従って、
U状杆2の径もそれだけ径大にできる。Therefore, the invention according to claim 2 provides a locking flange portion 9 of the nut cylinder 8.
In order to form a female thread of 9 degrees to the diameter and a diameter that allows the male thread of the joint male thread part 4 to be screwed through the through hole 13 formed by the locking flange part 9 of the nut cylinder 8, The diameter of the joint male thread part 4 of the U-shaped rod 2 is smaller than the case where the joint male thread part 4 is simply passed through the through hole 13 of the locking collar part 9 instead of being screwed in. The diameter becomes larger (see Figure 5), and therefore,
The diameter of the U-shaped rod 2 can also be increased accordingly.
第5図は、ネジの高さだけ径大になることを説けの径大
差が生ずることを示したものである。FIG. 5 shows that a difference in diameter occurs because the diameter increases by the height of the screw.
係止鍔部9の貫通孔工3に継合雄螺子部4を螺入し、ナ
ツト筒8をU状杆2の端部まで移動せしめると、U状杆
