The utility model discloses a tool for drawing a line on an insulating cylinder of a transformer coil, which comprises a body and a line pendant, wherein two side plates at the lower end of the body are the two waists of a right-angled isosceles triangle, and the bisecting line of a right angle is the elongation line of the central axis of an upper end plate of the body; and the upper end of a pull line of the line pendant is fixed on the central axis of the upper end of the upper end plate of the body, and the line pendant at the lower end of the pull line is lower than the connection point of the two side plates. The tool disclosed by the utility model is formed by utilizing the principle design of an isosceles triangular vertical line, i.e. a center line. According to the tool disclosed by the utility model, the line drawing accuracy is high, and the verticality of supporting strips and the distance tolerance of the supporting strips can be ensured. The tool has a smaller shape and a low cost, is convenien
