The support rods 122 are evenly distributed on the support side plates 121, and the number is 4. The axial direction of the support rods 122 is the same as the axial direction of the rotation axis of the wire winding roller. The rotation driving assembly 130 is a motor for driving the rotation of the wire paying-off roller 110 and the wire winding roller.
