PURPOSE:To enable revolution with a minor force and eliminate obstacles for work by furnishing a body frame placed upon a guide rail in the form of a long plate slidable with respect to a slide installed on a holding table at the top of a front leg, and drawing out the frame with revolution round a shaft at the top of a rear leg. CONSTITUTION:When a clamp knob 8 is revolved and retracted and the body frame 1 is drawn out by holding a grip to be revolved round a shaft of a rear leg, a guide rail 2 is held slidingly by a slide 3a of a holding table 3 furnished at a front leg 4a and moves smoothly toward the front face. At this time, the body frame 1 slides on the guide frame 2, but moves only in the longitudinal direction of the body frame 1 through sliding of a shaft 5a with groove 5b installed at the body frame 1 and guide frame 2, and is fixed levitadedly in the shorter direction and slided and revolved. The rod is inserted from the supply hole so that it does not run against the machine tool in a state the body frame 1 is drawn out.
