I call then expanding collets.
In lathe turning and similar operations you sometimes have to hold an object from the inside. These tools fit an exact size hole, and when tightened by the Allen screw, they expand and lock the object to the shaft. The object can then be chucked in a lathe and turned or other processes done.
