A special correcting device for a toothed rail quenching inductor relates to the technical field of correcting devices, is used for correcting the inner side and the outer side of a workpiece contactend of the toothed rail quenching inductor, and comprises a fixed bottom plate, a first positioning side plate, a second positioning side plate, an inner correcting block, a first outer correcting block and a second outer correcting block. The shapes and the sizes of the inner correction block, the first outer correction block and the second outer correction block are designed by taking the shapesand the sizes of the inner side and the outer side of the workpiece contact end of the toothed rail quenching inductor as models, the deformed toothed rail quenching inductor is corrected together, correction is accurate, and errors are not likely to be generated.
