Abstract
A pipe enlarging device includes a base, an operation unit and a clamping unit. The clamping unit is received in the base, and includes movable front and rear clamps and a front threaded rod. The front and rear clamps are resiliently movable when the front threaded rod is rotated so as to form an adjustable clamping area between the front and rear clamps. The clamping area is used to clamp pipes of different sizes. The operation unit includes a top threaded rod with a cone-shaped member which is used to enlarge the inner diameter of the pipes.
