The torsion spring (torsion spring) uses the principle of lever to twist or rotate the elastic material with soft material and high toughness, so that it has great mechanical energy.
It is a spring that bears torsion deformation, and its working part is also closely surrounded or separated around. The end structure of torsion spring is processed into various shapes of torsion arm. The deformation of torsion bar from single torsion to double torsion and even all kinds of torsion bar can be shaped according to design.
Torsion spring is often used in balancing mechanism of machinery, and is widely used in automobile, machine tool, electrical appliance and other industrial production.
