PURPOSE: A pipe plug is provided to reuse by easily fixing and separating the pipe plug from the end of an opened pipe. CONSTITUTION: A pipe plug comprises a cap(2), a gearing chuck(3), a wedge(4) and a bolt(5). The cap is formed in a handle to be stuck to the end of a pipe. A rotating guide is protruded in the lower center of the cap to maintain the rotating center. A female screw portion is formed in the inner center of the cap. The gearing chuck is stuck to an inner wall of the pipe by raising the wedge after inserting into the pipe or returned by falling the wedge. A rotation guiding groove is formed in the gearing chuck to be geared with the rotating guide. Many gearing blades are formed in the lower part of the gearing chuck. The wedge widens the gearing blades outward. A bolt slot is penetrated in the center of the wedge. The bolt is screwed with the female screw portion by penetrating the centers of the bolt slot and the gearing chuck. Thereby, the pipe plug is fixed and separated easily.
