1. The zipper is not flexible: the zippers of clothes, bags and trousers are damp or rusty, and the zippers are not smooth when pulled after oxidation. If the zippers are wiped back on two rows of pullers with candles and baked on the fire, they will be very slippery when pulled. 2. The zipper can't be opened: the common problem of metal zippers is that the zipper can't be opened or opened mainly due to the zipper head, which has been used for a long time. The solution: clamp the tail of the zipper head with pliers, but pay attention not to use too much force or clamp deviation. If you want to solve the problem thoroughly, replace the zipper head. 3. The zipper bursts: clamp the tail of the zipper head with pliers, but pay attention not to use too much force or clamp deviation, Replace the puller if you want to completely solve the problem

1. The zipper itself is of poor quality, easy to get stuck, and has no locking function. A zipper can be replaced for processing. 2. After the zipper has been used for a long time, the degree of lubrication is not enough, which causes the zipper to crack easily under the influence of external forces. This is one of the most common reasons. According to common sense, you can use candles or soap to lubricate this situation, so that it will not crack again. 3. The zipper is used incorrectly, which causes the zipper gear to be misaligned and split during the pulling process. In this case, just slowly return the zipper to its original position, and then pull it again. 4. If the zipper cannot be closed and opened together after the zipper head is pulled, the zipper head can be slightly clamped with pliers.

Common handling methods for zipper bursting after being pulled: prepare tools: candles, soap. 1. After closing the zipper, I found that the lower part of the zipper opened automatically. 2. Find a solid wax and apply it to the problem area of the zipper. It can also be applied to other areas. Scratch the zipper several times to solve the problem of being unable to move or stuck. Because the candle contains paraffin, it can play a role in lubrication. 3. After the candle is gently wiped on the zipper that is not easy to use, a part of the wax will be left on the zipper that is not easy to use, and then gently pull the zipper with your hand. The zipper that is not easy to use will be easily opened or closed. 4. If there is no candle at home, we can also use soap to rub the zipper back and forth, which can also solve the problem.
