Many different terminal devices or "hooks" are used to ensure the tension of the tension spring. The tension spring is the opposite of the working principle of the compression spring. The compression spring acts in the opposite direction when pressed, and the tension spring acts in the opposite direction when stretched or pulled. When the ends of the tension spring are opened, the springs try to pull them back together. Like a compression spring, the tension spring also absorbs and stores energy. But unlike compression springs, most of the tension springs are usually under a certain degree of tension, even in the absence of any load. This initial tension determines the tightness of the tension spring in the absence of any load.
