Extension Springs

 

The extension spring is a spiral spring that bears axial tension. Its hook forms include side hook tension spring, long hook tension spring, British hook tension spring, German hook tension spring, semicircular hook tension spring, duckbill hook tension spring, etc. "Hook" is used to ensure the tension source of the extension spring. It is generally made of spring steel with circular section material. When it does not bear load, The coils of the tension spring are generally tight without clearance and work with the resilience (tension) after stretching to control the movement of the parts, store energy, measure the force, etc. Most tension springs are usually under a certain degree of tension, even without any load.
