Name that clamp…

Greetings, would anybody know what the following “articulated” clamp / vise is used for? Any help is appreciated. Only marking is the embossed “LIFETIME” and a small diamond mark..

 

I would guess it's for mounting a work light on a bench. What's at the other end of the moveable arm?

 

That would make sense. It’s just a cut-off brass tube and nothing else. That’s for the reply.

 

Yep, I agree. It is a drafting table lamp clamp.
