As shown in Figure 1, we use to catch mice mouse clip on the use of torsion springs, the principle is very simple, I will not say more.
As shown in Figure 2, its mechanical components, applied to torsion springs, tension springs, compression springs for mechanical work.
As shown in Figure 3, its hardware accessories, with other components can be upgraded to a product with functional value
As shown in Figure 4, the hairpin is to make full use of the principle of torsion spring to work.
