It is, it’s like a friction fit. Up to hold it in, down to remove it. The yellow knob is actually stamped with words/arrows for up and down zzzSomehow I was thinking that was a shipping holder/support and not part of the jack, but I can't see it clearly enough. The jack looks partially extended/raised in both pictures.
Although now I'm wondering why the hole is in the bracket for the shaft to go through. If it was just a recess, the jack could be raised/extended enough to be a tight fit against it.
Edit to your last part your edit….lol….It kinda looks like top of the jack goes through but it doesn’t it is recessed..
