I accidentally took the top off my nail drill and all the pieces came out onto my table. Now I can’t reassemble it in a way where the chuck works.

Basically exactly that, I am nearly certain that these are all of the parts that came out of it. I have attempted to reassemble it in a few different ways, but the lock and unlock mechanism for the chuck doesn’t work anymore. If I trick the drill into thinking it’s locked. The motor still works.

Sometimes I reassemble it in a way where it works one time, but if I attempt to re-lock it after taking the first bit out and putting in a new one, that’s when it does stop working.

I cannot figure out the exact way that the collar with the little wheels is supposed to go into the pink collar with the ridges on the inside .

Please help I can’t get my manicure off without this. I use this tool for basically everything. It’s like a tiny Dremel.
