Compression Spring
Compression spring (compression spring) is a spiral spring that bears axial pressure.
Its material cross-section is mostly circular, but it can also be made of rectangular or multi strand steel wire. The spring is generally of equal pitch, and the shape of the compression spring includes cylindrical, conical, convex and concave shapes, as well as a small amount of non-circular shapes. There is a certain gap between the coils of the compression spring. When subjected to external loads, the spring shrinks and deforms, storing deformation energy.
