hello, did you find any sort of elastic metal device? I've disassembled my autoblade by mistake and there's a tiny elastic metal device that came out from it and I don't know how to put it back
To illustrate this a little better, what @pattygq said, but a very thin blade that can fit all the way in and along the horizontal line at the back....fit it in so it parts open a little, then gently tilt the pieces apart. Imagine it like making the head of the tool do a little nod.
