To facilitate transfer of a ring body and cutting of long materials.

With this tool, a movable carriage is moved by a stand retaining means 3 toward a central space B1 of a ring body B nearly vertically put up, a hanger 2 is inserted into the central space part B1. After that, the stand retaining means 3 is switched to an inclination retaining means 4 by an operating means 5. Thus, one side face B2 of the ring body B abuts against a receiving surface 1a, the ring body B is suspended diagonally by the hanger 2, and thus the ring body can be moved in suspended state by the inclination retaining means 4 and long materials A can be drawn out.
