This most commonly refers to the movable clamping elements found in a lathe chuck, which grip and hold a workpiece during machining operations. These jaws are typically designed to slide radially in slots and are actuated by a scroll plate or a system of screws, allowing them to grip workpieces of varying diameters securely and concentrically.
Beyond the machining context, "drejefjedre" might occasionally be used metaphorically to describe any rotating or pivoting
