Yes, I've made a couple similar pullers for getting around large irregular flange (and the steering wheel is a good example.)It is a puller of some sort, likely a condition where it can't get inside the part.
Or behind it.
So they clamp it by the OD.
So when have you met me LOLSome day you'll have something you need to pull apart or press together, you'll start thinking how to make something to do it, then you'll remember this thing... and you won't be able to find it.
