The twist lock mechanism no longer work and the pole will not lock.
There is a bolt through the middle followed by a plastic plate some
rubber and some more plastic.

I've tried this a few times, and the fix has never really worked for
long. That plastic plate or the rubber is actually a cam, and typically
either the outside edge gets worn or the center hole enlarged. See which
it is for you and try to correct.

Probably the most likely fix is to drill a hole through the two sections
so you can put a bolt or plunger-pin through to lock them together in
the extended position.
