The utility model relates to an installation tool for electric power circuit, in particular to a manufacturing support for an electric pole stay wire. The manufacturing support for the electric pole stay wire is composed of a stand column, a stay wire holder with a U-shaped groove and a base. The stay wire holder is fixed on the upper end of the stand column, the base is fixed on the lower end of the stand column, and the width of the U-shaped groove on the stay wire holder matches a diameter of the electric pole stay wire. The technical scheme of the manufacturing support for the electric pole stay wire is that a tail wire of a stay wire and a body wire are placed inside the U-shaped groove which matches the diameter of the electric pole stay wire and is on the stay wire holder, the tail wire of the stay wire and the body wire are positioned through the U-shaped groove, and therefore the manufacturing support for the electric pole stay wire brings convenience to wind of iron wires on one hand, and can guarantee technical requirements of winded tail wire of the stay wire and the body wire on the other hand. The manufacturing support for the electric pole stay wire has the advantages of being simple in structure, convenient to use and the like.
