The model

The nut sits in a pocket in the frame, and the screw is threaded through from the outside. The pressure cup sits on the screw tip, the counter cup in a groove in the frame. The handle sits in the turning knob and is secured with two glued-on end caps.

Between the cups there is room for nuts up to about 50 mm long. Checked by calculation: all parts mesh closed, half open and fully open without intersecting, and 0.28 mm of air remains between screw and nut.
