The invention relates to a stitch needle-bending tool special for a wheel speed sensor. The tool comprises a workbench, a first needle-bending component, a second needle-bending component and a workpiece positioning head, wherein the first needle-bending component, the second needle-bending component and the workpiece positioning head are arranged on the workbench; the first needle-bending component is arranged on the rear side of the workpiece positioning head; the second needle-bending component is arranged on the right side of the workpiece positioning head. Compared with the background technology, the tool has the advantages of simple structure, convenience in manufacturing, safety, reliability and high working efficiency; a sensor inner core is positioned on the workpiece positioning head, and a bending process is sequentially performed on two plugging needles extending out of the sensor inner core; the needle-bending components, such as a side needle bending arm, a top needle bending roller and a top needle baffle sheet are ingenious in manufacturing, and after the needle bending process is finished, a workpiece and the bent inserting needles are not scratched and damaged; the tool is suitable for batch processing and high in processing precision, and the product rejection rate is effectively reduced; a double-touch switch is adopted, and the needle-bending tool can be started by touch by the two hands of a worker, so that the two hands of the worker are enabled to depart from the tool, and the personal safety of the worker is guaranteed.
