Correct use of zipper accessories
Because the metal upper and lower ends are designed to penetrate the chain belt feet, the sharp parts will be accidentally exposed during the manufacturing and use process, and there are unsafe factors. Therefore, it is recommended that children's clothing choose zippers when choosing zippers. Use injection-molded top and bottom stops. The same goes for zippers used in underwear. For the open-end zipper, you must pay attention to insert the cannula into the bottom of the socket cavity, insert it to the end, and then pull the slider. Deformation or displacement of each element will cause the two sides of the element to not be able to articulate or pull the top of the head. If the cannula is not inserted in place, it is easy to cause damage to the plug-in. The correct method When the puller can't be pulled, please move the puller back a bit, and there will be no problem when pulling it when the intubation is in place.
