The resistance device 4 provides resistance for the rotating shaft 31, which can be a rotating wheel friction, magnetic resistance, fluid resistance, etc., but is not limited thereto. In this way, when paying off the wire, the copper wire passes through the lower eyelet 321 and then the upper eyelet 311 from the wire coil 1, and then the copper wire drives the wire paying-off frame 3 to rotate during the wire arranging process. And the resistance device 4 provides resistance for the rotating shaft 31, thereby providing tension for the copper wire during wire paying-off, and after stopping the wire, the resistance device 4 can brake the rotating shaft 31 to reduce the length of the excess copper wire.
