Rotating tool

A rotating tool for rotating a machine tool inserted in a machine tool retaining hole and performing work by rotating a rotating main shaft, wherein the rotating tool has a rotating main shaft;

• a driver bit, drill bit, or other machine tool is inserted in the rotating main shaft;
• and a machine tool retaining hole having a cross-sectional shape that substantially matches a polygonal cross-sectional-shaped base part of the machine tool is provided;
• said rotating tool characterized in that
• a pushing mechanism for pushing in a state facing the vicinity of an angled part of said machine tool inserted in said machine tool retaining hole is provided to said rotating main shaft;
• the pushing mechanism is configured so as to push in a state facing the vicinity of the angled part of said machine tool and rotate said machine tool, and twist and push the machine tool against an internal surface of said machine tool retaining hole so that the machine tool is rotationally offset from the machine tool retaining hole as viewed in cross-section while an axial center of the machine tool and an axial center of the machine tool retaining hole are aligned with each other;
• a locking groove is provided to said base part of said machine tool;
• locking bodies for locking in said locking groove and retaining said machine tool are provided to said machine tool retaining hole;
• a sliding tube that is urged towards a proximal end or a distal end is provided to said machine tool retaining hole;
• retention of the machine tool by said locking bodies is released, and twisting and pushing of said machine tool against the internal surface of said machine tool retaining hole by said pushing mechanism is released when the sliding tube is pulled towards the distal end or the proximal end against an urging force;
• and
• said locking bodies are placed in said locking groove, said machine tool is retained, and the machine tool is twisted and pushed against the internal surface of said machine tool retaining hole by said pushing mechanism when said sliding tube is moved back towards an opposite side by the urging force.
