turn it upside down. Inside the center hole is a screw. Use a flathead screwdriver and GENTLY turn it a little clockwise or counterclockwise.
I've taken these apart and really haven't seen any parts that wear out. Just the screw adjustment.
When I use mine, I do push down on the entire clamp when closing the clamp.
