[0018] The spring in the present invention is provided with a support spring, a first contact spring, a first contact ring, and the components cooperate with each other. At the same time, because the ring diameter of the first contact spring is large and the ring spacing is short, the force-bearing area of ​​the single spring is expanded, and the spring is accelerated to transmit pressure under the action of external force. By providing a main support spring, due to the ring diameter of the main support spring being small and the ring spacing being long, a vertical force can be formed between the rings when subjected to force, thereby resisting the impact of external pressure on the spring and increasing the spring's rebound work distance, thereby shortening the distance the spring rebounds under force and shortening the rebound feedback time.

[0019] By providing a second fitting spring, when the force reaches the second fitting spring, the force-bearing surface becomes narrower from wide, which can reasonably reverse the force focus point of the pressure, so that the force of the spring is transmitted according to the designed line, reducing the resonance caused by the spring being stressed, thereby reducing the generation of noise, and gathering force to the bottom of the spring to recover the external impact pressure.
