Folding Fan Rigging

Hello.
I want to create Folding Fan Rig, kind of this image.


I’ve tried. But some rigging connections don’t work well.
A bone damped constraint out of control.

I was thinking various way to build.
But I could not find a best way.
I have to use IK ? or other constraint, which bone must be parent …

please give me some advice.
I upload .blend file.
