It moves smoothly by the rotation of the receiving cylinder. Even if the frictional resistance prevents smooth movement, the guide roller disposed inside the receiving cylinder rotates to increase the rotation of the receiving cylinder. Is smoothly carried out. In addition, the frictional resistance due to the tension (on a curved road) acting on the side rod portion of the tool body during the movement of the cable reduces the resistance as much as possible due to the presence of the guide roller.

受支筒9は回動して該作業は円滑に行われる。Then, the hooks 5, 5 of the main rod 1 are hooked on the existing hanging wire a, and the extension tool A is provided at an appropriate distance from the hanging wire a (note that the hanging wire a is connected to the hanging wire a). Since the cable C 'may be suspended, the side rod portion 3 is arranged so that the newly installed cable C or Ca is arranged below the cable C'.
May be lengthened in the vertical direction, or the length of the inclined rod portion 4 may be increased as shown in the figure), or the cable C or Ca may be placed on the receiving cylinder 9 to perform a wire drawing (traction) operation. ,
The receiving cylinder 9 rotates to perform the operation smoothly.

に何等支障がない。[Effects of the Invention] Since the present invention has the same configuration as before, each of the auxiliary roller and the receiving support cylinder freely rotates, so that the frictional resistance generated when the cable is drawn is absorbed and the drawing work is smoothly performed. Can be done. In addition, since the guide roller is rotatably mounted on the side rod portion of the tool body, even if tension is applied to the side rod portion during cable pulling work, the presence of the guide roller reduces frictional resistance as much as possible. Therefore, there is no problem in using it on an extension line having some bends.
