Through the reasonable setting of the position of the three wheels of the line unit and the three wheels of the line unit are walked to the downside to the upside for the overall structure of the wire cutting system is simple in structure under the premise that the line can be walked. The setting mode is specifically as follows: the upper edge of the reversing wheel of the upper wiring unit is coplanar with the upper edge of the tension wheel, and the lower edge of the tension wheel of the upper wiring unit is coplanar with the upper edge of the wire arranging wheel; the lower edge of the reversing wheel of the lower side wiring unit is coplanar with the upper edge of the tension wheel, and the lower edge of the tension wheel of the lower side wiring unit is coplanar with the upper edge of the wire arranging wheel.
