The invention provides a double wheel disc manual bending tool for a high-pressure oil pipe. The double wheel disc manual bending tool comprises a positioning pin, a large wheel disc, a fixing pin, a base, a bolt, a wheel disc supporting body, a handle and a small wheel disc. The small wheel disc is fixed to one side of the wheel disc supporting body through the bolt. The fixing pin sequentially penetrates through the other side of the wheel disc supporting body, the large wheel disc and a connecting hole in the base to fix the large wheel disc to one side of the base. A plurality of positioning pin holes are formed in the base, and the positioning pin can be inserted into any one of the positioning pin holes. The handle is mounted to the end, where the small wheel disc is mounted, of the wheel disc supporting body. The double wheel disc manual bending tool has the following advantages that in the early engine test process, the double wheel disc manual bending tool can adapt to various arrangement schemes of high-pressure oil pipes of oil supply systems rapidly and conveniently, is suitable for bending and shaping of small-batch high-pressure oil pipes, and can bend the high-pressure oil pipes freely by 0-180 degrees, and the modification period of the oil supply systems and the test coordination period of the engine are shortened.
