Background

Springs are one of the common components in mechanical design and are often used to provide elastic support, provide preload, assist in part return, or provide cushioning. The type of spring is also quite diverse, for example a disc spring, a torsion spring, an extension spring, a spiral spring or a compression spring. However, in daily life, it is most commonly used and also most common to use compression springs.

A common compression spring is formed by spirally extending a wire made of a metal material. With the development of material science and the progress of manufacturing methods, compression springs made of plastic materials are becoming more and more popular. The magnitude of the spring force of this type of compression spring is generally determined by the diameter of the wire body, the number of turns, and the spacing between the turns. The pitch of the compression springs is one of the important parameters that are referred to when calculating the elastic force of the compression springs.

However, in the conventional compression spring, the wire body is generally solid. When the compression spring is fully compressed, the spacing between the compression springs is eliminated and the helical wire bodies are pressed tightly against each other, so that the compression spring cannot be further compressed. Thus, the existing compression springs of solid wire bodies have no way to provide any further cushioning after they have been fully compressed. Therefore, when the conventional compression spring of the solid wire body is used to provide a buffer for a precision instrument, or is used to support an object above the precision instrument to prevent the precision instrument from being pressed by the object above, the precision instrument is damaged and excessively damaged due to the fact that no further buffer function can be provided.
