How to repair the clockwork toy duck

1. Open the body shell, take out the clockwork, and then use pliers to pull the clockwork round and round, and straighten the clockwork while pulling.

2. After taking out the clockwork, take out the broken clockwork on the belt buckle with needle-nosed pliers and replace it with the same clockwork.

3. If you don't have a new spring at hand, you can smooth the broken part of the original spring, put it on the fire to burn it red, let it cool and anneal itself, and then put the processed spring in.

4. If the gear slips or is loose, replace the corresponding gear or weld the gear with ferrochrome.
