Turn blue screw of eccentric head to clamp or release yellow workpiece.
The hexagon of the pink jaw is eccentric to its cylindrical hole. It has 6 different distances from side surfaces to the hole center.
Turn the jaw in relation with the screw before clamping to adapt to the workpiece size.
There is a considerable axial gap between the screw and the jaw so the screw doesn’t clamp the jaw on the base.
It’s used for lowprofile edge clamping.
