Hallo!
I have a problem

One of my cathedral heads of this poi set:
cathedral poiset opend up.
So i want to ask if somebody knows how they are built up.
I was doing ttn (aktually i was learning it and smashed the heads together a few times) when suddenly one poi opened and some things flew away. Now im not sure if i found every part.
My mainquestion is: How is the screw fixet to the wick?
I think they will be built up by the use of this:
screwis the holder (i dont know if this is the right word. the thing that fixes the screw) hiden unter the wick?
Do i have to cut them open for fixing this problem?
sry for my bad englisch and thx for ur help
