1, divided by use: tension spring, torsion spring, compression spring, etc.

2. According to materials: copper spring, alloy spring, steel wire spring, titanium alloy spring, etc.

3. According to the shape: tower spring, rectangular spring, straight spring, single and double torsion spring, etc.

Torsion spring:

Torsion spring (torsion spring) is an elastic material with soft and high toughness, which makes it have great mechanical energy by twisting or rotating the material by using the lever principle. It is a spring subjected to torsional deformation, and its working part is also closely surrounded or separately surrounded by coils.

The end structure of the torsion spring is processed into various shapes of torsion arms, from single torsion to double torsion, and even the deformation of various torsion bars can be modeled according to the design. Torsion springs are commonly used in mechanical balancing mechanisms and are widely used in industrial production such as automobiles, machine tools and electrical appliances.
