2: Springs and other elastic parts are most vulnerable to damage during use, and usually breakage and deformation occur. The method adopted is to replace. In the process of replacement, we must pay attention to the specifications and models of the spring. The specifications and models of the spring are confirmed by the color, outer diameter and length. Only when all three items are the same can be replaced. The spring is preferably of the quality of the inlet.
