Because the elastic supporting device supports the right end of the lever mechanism, the lever mechanism can swing up and down during work, so that the tension of the wire during the coiling process can be adjusted to keep the tension constant, as shown in Figures 5 and 6. When in use: ①The electric wire is pulled from the pay-off frame 21 to the upper end of the first guide wheel of the fixed guide wheel set 1 through the lead post 20, and then bypassed from the lower end of a guide wheel corresponding to the floating guide wheel set 3, and pulled Back to the upper end of the second guide wheel of the fixed guide wheel set 1, bypass the lower end of a guide wheel corresponding to the floating guide wheel set 3 again, pull back to the upper end of the third guide wheel of the fixed guide wheel set 1, and again from The lower end of a guide wheel corresponding to the floating guide wheel set 3 is bypassed, pulled back to the upper end of the fourth guide wheel of the fixed guide wheel set 1, bypassing the lower end of the fourth guide wheel of the fixed guide wheel set 1 and drawn to the lower end of the guide wheel 4 Through the pressing wheel 6 and the wire passing wheel 8, the electric wire is wound around the upper end of the next wire-guiding wheel 22 by the lower end of the previous wire-guiding wheel 22 and finally arrives at the line-forming disk 24.
