Abstract
The utility model discloses an exhaust pipe bending structure. The exhaust pipe bending structure comprises a rotating disc. A pipe bending groove is formed in the rotating disc through a rotating shaft in a rotating mode. A threaded groove is formed in the rotating disc. A threaded rod is arranged on the threaded groove. One end of the threaded rod is connected with a rotating handle through a hinge. A connecting rod is arranged on the rotating handle. The exhaust pipe bending structure further comprises a wheel base and an exhaust pipe clamp which are arranged on the rotating disc. A trapezoid groove is formed in the wheel base. One end of the connecting rod is arranged in the trapezoid groove in a sliding mode. A plurality of wheels are arranged in the wheel base. A guide groove matched with the pipe bending groove is formed in each wheel. When the rotating handle is pressed downwards, the connecting rod can slide in the trapezoid groove by a distance so that it can be ensured that force is uniformly exerted on the wheel base. The contact area between the guide grooves and the bent portion of an exhaust pipe is enlarged due to the wheels arranged on the wheel base. It is ensured that force is uniformly exerted on the bent portion, and therefore the phenomenon that the exhaust pipe is directly broken up or cracks occur in the bent portion of the exhaust pipe is reduced, and the rejection rate of the exhaust pipe is decreased.
