How is it that the jasper mop can't turn the bucket?

This problem also happened to my good god mops. I turned the mop bucket upside down and squeezed where I stepped. When I put it in the square, the bucket will turn, but it won't. I took apart the screws at the bottom of the bucket and removed the power part of my feet. After inspection, it was found that it was not the power supply. There is a metal stick under the mop bucket, which is a bit loose. The other end of the stick is inserted in the middle of the pinion of the power system. Find some tin foil paper (a small amount), plug it into the small hole in the middle of this gear, push it with a screwdriver and reassemble it. The amount of tin foil is increasing bit by bit. Try adding a little. If you take too much, you can't take it out. The middle spin bucket will turn, but the pedal won't come back. Just loosen the screws and debug. That's what my family does. This is a worn pinion. Just go to Taobao and buy a suitable model substitute.
