Apparently this is something that actually exists and you can buy... looks like an AI-fail to me, but maybe it has some advantage over at adjustable wrench and vice-grips? https://www.amazon.com/dp/B08L6V5WV8
I think it also clamps the jaws by pushing the worm screw tightly.
It's an alternative to the thumb screw at the bottom of ordinary locking pliers. Maybe more convenient to use with one hand.
