The utility model discloses a metal wire winding device. The metal wire winding device comprises a support, a supporting shaft, a rotating shaft and two bearings. The supporting shaft comprises a first connecting part and a second connecting part which are fixedly connected with the support, and the rotating shaft is mounted on the second connecting part through the two bearings. When an operator needs to use the metal wire winding device for winding a metal wire, one end of the metal wire is fixed on the rotating shaft first, the metal wire is straightened by one hand of the operator, then the other hand of the operator operates the rotating shaft to rotate, and at last the metal wire is wound on the metal wire winding device. By means of the metal wire winding device, winding work of the metal wire can be achieved by rotating the rotating shaft, and the metal wire only needs to be straightened by one hand of the operator; hence, the metal wire winding device effectively lowers the labor intensity of the operator for winding the metal wire.
