Find an ordinary wooden stick as a hammer, hold the bracelet and the thick wooden stick mold worn on the bracelet in one hand, and slowly beat the surface of the bracelet with a wooden hammer with the same strength, and observe the deformation state of the bracelet surface while beating, so as to reshape the bracelet surface. Under the reaction of the wooden stick mold worn inside, the surface of the bracelet to be broken will gradually become a regular circle.

2. Straighten the bracelet first, then gently tap the place with a small bend with a hammer wrapped in thick cloth, and finally it will become a slow arc. Find another wine bottle, a little smaller than the original caliber, press it on it and wind it up hard. Be sure to press it to the end. One last lap, and it's done. At this time, the bracelet will rebound and the caliber is appropriate.

3. Go to the jewelry processing shop to reprocess the silver bracelet.
