Novel tensile high-toughness coated copper wire

The utility model belongs to the technical field of coated copper wires, and discloses a novel tensile high-toughness coated copper wire, which comprises a support assembly, a detachable winding assembly is installed on the supporting assembly. The winding assembly can rotate relative to the supporting assembly, and the winding assembly is used for winding the coated copper wire; a plurality of annular grooves are formed in the coated copper wire at equal intervals, and the winding assembly comprises a winding roller; a containing groove used for winding a coated copper wire is formed in the circumferential face of the winding roller. The supporting assembly comprises a supporting frame. A side groove is formed in one side of the supporting frame; the bottom end of the inner side of the side groove is fixedly connected with a supporting pipe. According to the utility model, the clad copper wire is bent and the annular groove is matched, so that the clad copper wire at the bent part is broken from the bent par
