two explanations about the operation and an image of the open position you could well put them?
let us go of imagination: the clamp is the blue part that opens turning upwards when the upper group moves to the left, thus freeing the red part.

we come to the constraints: I would impose a rotation axis, impose an angular limit to be associated with a rack-type bond with the moving part to open the clamp. The cam bond could also help.
Now I've fallen the connection of the crystal bowl so I can't traverse any further.

If by chance the system works totally different from what I imagined... I read my proper answer

p.s. but when you relate (the plural is about a myriad extermination of designers who write here) with your customers/suppliers you are always so unclear to request/supply project specifications? If so, I explain the exorbitant cost of certain industrial products and above all their poor duration, which goes well below the planned obsolescence. :redface:
