When pulling the axle out after disengaging the quick connect, the shaft won't push through and the other side all the little metal pieces fell out.
Tire won't come out and cannot put it back together. Now what?
Brand is "Suntour Q-Loc axle"
If you just opened the lever as looks from your answer now, you may need to unscrew it additionaly, try to rotate the bottom side (as in the photo) "knob". Do not overtry however as the core will come out. Otherwise pull the lever out on another side. With a little bit more force these metal segments that are now spread should come together and pass through the hole in the fork.
