[0033] To sum up, when the utility model is working, the first wire harness and the second wire harness pass through the first wire threading hole E1 and the second wire threading hole E2 of the wire support E respectively, and pass through the first wire feeding wheel group 4 and the second wire feeding wheel group 5, and then pass through the first conduit F1 and the second conduit F2 from the first spring conduit F3 and the second spring conduit F4, and the first driving module 8 and the second driving module 9 independently drive the first wire feeding wheel group 4 and the second wire feeding wheel group 5 to rotate for feeding. When the first wire harness and the second wire harness need to be transmitted at the same speed, the first driving module 8 and the second driving module 9 drive the first wire feeding wheel group 4 and the second wire feeding wheel group 5 to rotate at the same speed, and when the delivery lengths of the first wire harness and the second wire harness need to be different, the first driving module 8 and the second driving module 9 need to drive the first wire feeding wheel group 4 and the second wire feeding wheel group 5 to rotate at different speeds. At this time, the lengths of the first wire harness and the second wire harness delivered through the first wire feeding wheel group 4 and the second wire feeding wheel group 5 are different, thereby ensuring the production requirements of different products.
