The invention discloses a positioning tool for installing a magnetic pole connecting wire. The positioning tool comprises a positioning plate and a fixing plate, wherein the top of the positioning plate is provided with a first binding surface and a supporting surface, the bottom of the positioning plate is provided with a second binding surface, the first binding surface and the second binding surface are arranged in a coplanar manner, and the fixing plate is fixed on the positioning plate through a fastener and used for clamping a magnetic pole lead on the second binding surface. The positioning tool is simple in structure, facilitates the adjustment of the horizontal position of the magnetic pole connecting wire, and improves the fixed pulling accuracy of the magnetic pole connecting wire. The invention further discloses a hole matching method for installing the magnetic pole connecting wire, which comprises the steps of fixing the positioning plate on the magnetic pole lead; screwing an adjusting nut on the screw; marking the fixing position of the magnetic pole connecting wire; and preparing a positioning hole for the screw to penetrate through in the marked position. By meansof the method, the horizontal position of the magnetic pole connecting wire is convenient to adjust, the fixed pulling hole in the magnetic pole connecting wire and the screw are accurately positioned when an attaching part is attached to the magnetic pole lead, and the service life of the magnetic pole lead is prolonged.
