Pipe bender

The utility model belongs to the field of pipe benders, discloses a pipe bender, and aims to solve the problems that different bending radiuses of the conventional pipe bender are adjusted by arranging positioning wheels with different diameters, but the adjustable bending radiuses are all fixed values and cannot be adjusted at will when the conventional pipe bender is used, and certain limitation exists when the conventional pipe bender is used. Comprising a base, a mounting hole is formed in the base, a circular truncated cone is fixedly mounted on the top surface of the base, a disc is arranged above the base, a through hole is formed in the middle of the disc, and the circular truncated cone penetrates through the through hole. The bending diameter of the pipe fitting is adjusted by adjusting the contact position of the pipe fitting and the circular truncated cone, the circular truncated cone is arranged, the bending diameter of the pipe fitting is adjusted by adjusting the contact position of the pipe fi
