Meanwhile, the elastic pull rope 34 can also make the spring have a buffering force when the spring is restored to the original state, and the spring cannot rebound immediately at the moment when the pulling force disappears, so that the sliding sleeve 32 and the damping shell 31 are violently collided, and the rebound sound is further reduced. And then make spring 3 slowly kick-back under the frictional resistance of air resistance, spacing ring 321 and damping shell 31 and the effect of elasticity stay cord 34 three, sound is kick-backed in furthest's reduction, improves user's use and experiences.
