The subject innovation is the possible application of the product, preferably by one of the first section the process of bending to be bending the pipe at a predetermined angle or bent in a loop shape in a narrow space, improves the work efficiency, it does not damage the surface and the coating of the pipe and to maintain the quality, and ease of work due to a musculoskeletal finger or wrist like a bunch of things I do not aim to provide a portable pipe bendinggi to help prevent accidents such as the prevention, Portable pipe bendinggi according to the present invention for achieving the above object, the handle unit; Extension and extending a predetermined length from one end of said handle portion; And installed to be mutually predetermined distance spaced in the extending portion, and the insert is an outer peripheral surface portion of the pipe to be bent is inserted, groove includes a first protruding member and the second protruding member formed each concave along the outer peripheral surface, with the first projecting member of claim in position the pipe to be bent state between the second projecting member, said first projecting member and the second protruding missed one is in contact with the portion to be bent so bending the pipe at an angle, or a loop-shaped bend during bending, and the other It is characterized in that the support is in contact with one side of the pipe so that the pipe is bent. Portable pipe bendinggi
