Many different terminal devices or “hooks” are used to ensure the pull force of the tension spring. The working principle of tension spring and compression spring is opposite. The compression spring acts in the opposite direction when pressed, and the tension spring acts in the opposite direction when it is stretched or pulled apart. When the tension spring is pulled apart at both ends, the spring will try to pull them back together. Like compression springs, tension springs absorb and store energy. But unlike compression springs, most tension springs are usually under a certain degree of tension, even without any load. This initial tension determines how tightly the tension spring coils without any load.
