Drill a hole with an impact drill, then add rubber particles, and then add self-tapping screws, which can bear a suspension force of more than 5 kg and about 20 kg. Most people may not have impact drills at home, so they can find some home appliance repair departments to deal with them. It's very simple. The cost is about 3 yuan, plus the labor cost of the maintenance staff, and it will be done within 10 yuan.

There is no other way to cure this disease, and I have tried many times.
