The utility model relates to a transposition lead right-angle bending tool belonging to the technical field of transformer tool equipment. The utility model comprises a first handle (1), a second handle (2), a pinch roller (3), a connection shaft (4), rolling wheels (5), and a baffle plate (6). Each of the first handle (1) and the second handle (2) is provided with the rolling wheel. A notch is disposed in the rolling wheel, and cooperated with the transposition lead. The end of the handle is in the shape of a right-angle, and the rolling wheel is insertedly disposed in one edge of the right-angle. The pinch roller is disposed at the intersection between the two right-angle edges. The other right-angle edge is hinged on the rolling wheel shaft of the first handle, and the rolling wheel shaft also can be called connection shaft. The baffle plate is disposed on the end of the first handle, and fixed on the connection shaft. The baffle plate is horizontally disposed on the notch of the rolling wheel of the first handle. A transposition lead (7) is disposed on the notch between two rolling wheels. By moving the first handle and the second handle, the cooperation of the notch of the rolling wheels and the transposition lead and the cooperation of the pinch roller and the rolling wheel can be used to squeeze the transposition lead to limit the deformation of the lead and to form the right-angle elbow through bending the lead. The utility model is characterized in that by using the special tool to finish the transposition lead right-angle bending, the working efficiency and the product quality can be improved.
