A shock absorption device includes an inner cylinder assembly threadably engaged within an outer cylinder assembly. The outer cylinder assembly includes a cap shaped member, at least one protruding member, and at least one first spring member. The inner cylinder assembly includes at least one compressive member, at least one second spring member, and at least one movable piston member. When an external impact force is applied to the cap shaped body member, the first threaded portion of the outer cylinder assembly jumps over the second threaded portion of the inner cylinder assembly as provided by elastic movement of the resilient ring member about the cap shaped body member. The thread jumping results in the first spring member compressing and the protruding member pushing the piston member which pushes and compresses the second spring member and the compressive member providing a reactive force to absorb the external impact force. 11.
