Tension springs (Extension Spring) is subjected to axial tension coil spring, tension springs are generally circular cross section with the material. When not bear the load, are generally tight and there is no gap between the coils of the spring tension. Tension springs (Extension Spring) in contrast to the tension spring works. Tension springs back when pressed role in the tension spring is stretched or pulled back in time. When both ends of the tension spring opened, the spring will attempt to keep them back together. Many different terminal devices or "hook" is used to ensure that the source of the tension spring tension. Tension springs commonly used in medical respiratory equipment, motion control, medical and mobile devices, hand tools, home care equipment, damping, spring pump, mechanical and electronic protection hardware, fluid control valves, mechanical aerospace parts, actuators, switchgear .
