張り出した状態で取着けられている。The connecting portion 9 is a supporting portion, and has a rear end portion 11 for connecting a drawstring portion 10 made of metal such as stainless steel. By the way, in the case of the present embodiment, the conical front conducting portion 7 at the tip is made of a rocket-type metal, but if it has a pointed conical shape,
The shape and material can be appropriately selected. Behind the first conducting portion 7, a blade portion 8 such as a leaf spring 8a is attached in a state of protruding in an elliptical spherical shape.

長以上の長さのものが望ましい。The leaf spring 8a is formed by bending a number of piano wires, firstly conducting, silver-brazed on the outer periphery of the rear portion of the portion 7, and composed of a number of separated assemblies just like a chasen. I have. In the case of this embodiment, the blade section 8 is composed of four leaf springs. Therefore, each leaf spring 8a-8 of the blade part 8
When a is inserted into the outer circumference smaller than the outer diameter in the expanded state, the diameter of a is automatically reduced to a small value, and is urged to rebound when opened. The outer diameter of the blade 8 must be able to be inserted into the inner diameter of the spiral support 3 at least in a reduced state. Also the wings 8
Is required to be longer than at least one pitch length P of the spiral support 3 in FIG. 3, and preferably a length of two pitches or more.

みもすることができる。The connecting member 9 is provided with a sleeve 12. That is, in the drawstring passing device 6 of the present invention, when each of the elliptical spherical leaf springs 8a to 8a is in the state of the original expanded and large outer diameter, the center wire 13 in the sleeve 12 is in the direction of the arrow T. . On the other hand, when each of the leaf springs 8a to 8a is in a state where the outer diameter is reduced and reduced in the spiral support 3, the center wire 13 in the sleeve 12 is extended in the direction of the arrow S. In this reduced state, not only feeding but also pulling can be performed.

有するものである。However, if the outer diameter D of the elliptical sphere of the blade 8 is too different from the diameter of the helical support 3, the excessively large outer diameter D will not work if it is too large, and will become unstable if it is too small. Therefore, the drawstring passing device 6 of the present invention has an elliptical spherical outer diameter D composed of the blade portions 8 of the leaf springs 8a to 8a.
Can be adjusted in advance by the connecting portion 9. Thereby, the outer diameter D of the elliptical sphere can be adjusted in advance in accordance with the diameter of the spiral support 3, and this is characterized in that it can be adjusted in advance.

て、挿通時のスライドには支障がない。A sleeve 12 is connected to the connecting portion 9, and a rod 15 having an external thread 14 is provided on the outer periphery of the rear end of the sleeve 12. On the outer periphery of the rod 15, a female screw 16 screwed to the male screw 14 is provided, and a spring 17 is provided between the female screw and the connecting portion. Therefore, when the female screw 16 is turned, the connecting portion 9 moves forward and backward. That is, in the direction of arrow T, the outer diameter D of the elliptical spherical blade portion 8 expands and increases. Further, when the elliptical spherical blade portion 8 is shifted in the direction of the arrow S, the outer diameter D is reduced. However, the urging of the spring 17 does not hinder the slide during insertion.

発明の引き紐通し具6は、これ等の施工に使用される。When the draw string passing tool 6 reaches the other electric pole 1b, a cable laid at the rear end of the draw string portion 10 is connected. Then, the drawstring 10 is wound up by a winch (not shown), and the cable is drawn into the diameter of the spiral support 3. In this case, although not shown in the figure, between the electric poles 1a and 1b, the next between the electric poles is further connected with the drawstring passing tool 6 respectively.
After the pulling ropes are laid between the utility poles by using the above method, if both ends of the respective ropes are jointed, it is possible to pull in a long span at a time. In addition, when the cable is additionally constructed, although not shown, the same applies if the drawstring passing tool 6 is inserted into the diameter of the spiral support 3 in which the messenger wire 2 and the cable are already inserted. The drawstring passing device 6 of the present invention is used for these constructions.
