Machine Tool Fixture

Turn brown screw to clamp or release yellow workpiece.
The blue and green clamping jaws may not move synchonically but at the end they clamp tightly the workpiece that is centered in the fixture base (equalizing clamping).
Green and blue screws are stoppers for the green and blue jaws respectively. The blue jaw and the violet slider have threaded holes.
Many equalizing clamps have limited rigidity. If the portion of the part being clamped were subjected to heavy cutting force, the part could move the clamp. In such instances a locking device may be added. Here such device consists of orange lever-screw, violet and pink sliders. It clamps the green jaw after the yellow work has been clamped (last scene of the video).
