Specifically, the present embodiment provides specific values for the monofilament 12, wherein the diameter ratio of the monofilament 12 to the conductor 11 is 1: (2.5-3), exemplary diameter ratio is 1:2.5, the diameter of the monofilament 12 is 0.08-0.12 mm, and the spiral pitch of the monofilament 12 is 1-3 mm.
