The compression spring (compression spring) is a coil spring that is subjected to the pressure.The material used is mostly circular, rectangular, and the spring is generally equidistant.The shape of the compression spring is:cylindrical,conical,convex.The shape and the concave shape and a small amount of non-circular shape,etc.The compression spring has a certain gap between the ring and the ring, and when subjected to an external load,the spring shrinks and deforms,and the deformation energy is stored.
