Very interesting! The auction link shows a spring that is missing on mine.I looked at these pics a while back and I knew I had seen something like these in my past.
The old brain cells finally fired and I think they are pliers made to remove broken light bulbs from lamps. To remove the broken screw in socket. The two notches by the handles are what keyed me to these. Also, they spread apart when squeezing, so they are either snap ring pliers or O-ring pliers.
I made something that looked about like these when I was in a HS shop class 40+ years ago.
Then I started searching and found many of the same references as @Malleus .
But below is the final one I think that is what it is, but doesn't specify its exact use.

Excellent. Will pack with care and ship fast.www.worthpoint.com
Hmmm.... Haven't had a light bulb twist off its screw base in a long time, thanks to LED bulbs, so it's unlikely I'll ever get to test your theory. But it does make sense!
Thanks!
