The coiled pin is designed based on the concept of a helical spring, consisting of a coiled, flexible cylindrical pin. The elasticity of the coiled, flexible cylindrical pin allows it to be pressed into a hole and retain its elasticity after installation.
During assembly, the stress transmitted to the pin, as well as applied loads, vibrations, and impacts, are evenly distributed throughout the entire coiled, flexible cylindrical pin. This characteristic, along with the pin's strength and the uniformity of its elasticity, is inherent to the design of helical springs.
Stress concentration can lead to a particularly vulnerable point, resulting in premature fatigue failure of the component. The coiled, flexible cylindrical pin avoids this stress concentration at any single point.
