[0009] Compared with the prior art, the utility model has the following advantages: the thin-walled tube special-shaped bending tool provided by the utility model overcomes the defect that the thin-walled tube is easily squeezed and deformed by the traditional tool, and the first U-shaped wheel and the second U-shaped wheel are provided, so that the thin-walled tube can be effectively supported when being bent, thereby avoiding the deformation of the tube. At the same time, through the design of the rubber rod and the plastic ring, the rubber rod and the plastic ring extend into the bending part of the thin-walled tube, which can effectively support the deformation of the thin-walled tube during the bending process, thereby avoiding the occurrence of the tube body being squeezed and flattened. The internal support of the rubber rod and the plastic ring can maintain the shape integrity of the thin-walled tube. BRIEF DESCRIPTION OF THE DRAWINGS
