The nut sits in a pocket in the frame, and the screw is threaded through from the outside. The pressure pad slides sideways onto the screw tip, and the soft jaw (serrated or smooth) sits in a groove in the frame. The handle sits in the turning knob and is secured with two end caps that you glue on.
Checked by calculation: all parts mesh closed, half open and fully open without intersecting. 0.28 mm of air remains between screw and nut.
