Introduction
The elastic component can also be called general spring. It produces elastic deformation under the load function, remove the load can still restore original geometry size and shape.
Elastic component can complete transformation, isolation, seal, compensation, a variety of different functions such as energy storage and connection. Due to its simple structure, easy to manufacturing, low cost, phyletic and various, it has extensive application. Machines, electrical components, many instruments and life appliance need to apply elastic element ingeniously to complete its important function. In some instruments and meters, it is one of the basis of the main components, especially as a sensitive element, its quality directly affect the reliability and precision of the instrument. All kinds of elastic element used their structural characteristics, different materials and deformation to complete different function.

The function of the elastic component:
1. Buffer damping control movement
2. Controlling the movement
3. Storing energy
4. Measure
5. Guide and support element, adjust zero, locating and clamping.
