It is to be noted that the length of the groove wall of the pushing support seat 33 is less than the distance between the clamping shaft 20 and the winding support seat 25, so that the length of the pushing roller 34 meets the requirement of tightly winding the flat copper wire 32 along the radial direction of the rotor 61. When the flat copper wire 32 is wound along the radial direction, the flat copper wire 32 slides along the axial direction of the pushing roller 34 between the two pushing rollers 34, so as to prevent the pushing roller 34 from being worn at only one place.
