ワイヤー取付作業が正確に行なえるようになる。 As described above, according to this invention, a pantograph mechanism is constructed by connecting a pair of clamping rods and two links, and one clamping rod has a wire holder, and the other clamping rod has a half that clamps the wire. Since the clamping cams each have an arcuate surface, a wire clamping force corresponding to the tensile force is generated between the clamping cam and the pedestal, and there is no slippage against the tension of the wire. Now it can be fully tensioned without causing damage due to slipping.
Wire installation work can now be done accurately.

挾持力を与えることがなくなり、ワイヤーの寿命
延長が可能になる。 Furthermore, since an induction guide is attached to the pantograph mechanism, the wire clamping interval can be determined using this guide, and the optimal clamping force according to the wire diameter can always be confirmed, thereby avoiding unnecessary clamping force on the wire. This eliminates this problem and extends the life of the wire.
