The invention provides an auxiliary manufacturing device for a connecting structure at the tail end of a pole guy. The auxiliary manufacturing device comprises a supporting base, a lead screw transmission mechanism, a front compression mechanism, a back merging mechanism and a winding mechanism. The lead screw transmission mechanism is arranged on the supporting base; the front compression mechanism is arranged at the left end of the supporting base and used for fixing front parts of two side-by-side wire bodies formed by bending the pole guy; the back merging mechanism is used for tightly merging the back parts of two side-by-side wire bodies formed by bending the pole guy; and the winding mechanism is used for winding an iron wire to the positions, between the front compression mechanismand the back merging mechanism, of the two side-by-side wire bodies. By means of the front compression mechanism and the lead screw transmission mechanism provided by the invention, the pole guy canbe bent smoothly and the bent part of the pole guy and a connector are tightly attached. By means of the winding mechanism and a wire jacking mechanism, the iron wire can wind tightly, so that the winding working efficiency is improved favorably and meanwhile, the winding quality can be improved.
