Nowadays, with the development of science and technology, spring has become a very important hardware accessory in our life. Different products use different springs, and the longest used springs can be roughly divided into: pull spring, twist spring, press spring, disc spring and plate spring.The following features of a very practical tension spring:
Many different products or hooks are used to guarantee the source of the tension of the tension spring. The tension spring works in the opposite way to the compression spring. The tension spring works in the opposite way when stretching or pulling.
The tension spring is usually stretched to a certain extent, even when there is no load at all, and this initial tension determines the tightness of the tension spring without any load at all.The greater the extent of the extension, the greater the strength of the rebound within the limits allowed.
