Flexible support shaft

摘要

A flexible support shaft (10) configured to be arranged on a first object to flexibly support a second object moving relative to the first object is provided. The flexible support shaft comprises a first connecting flange (20) for being mounted on the first object, a compression spring (30) having one end arranged on the first connecting flange, an elastic member (40) configured to be embedded by the compression spring to change the elasticity of the compression spring, and a second connecting flange (50) arranged on the other end of the compression spring to support the second object. Because of the design of the compression spring and the elastic member thereon, the flexible support shaft acts not only as a support but also as a shock absorber for the second object in relative motion. Furthermore, since the compression spring is embedded in the elastic member, the elastic member changes the elasticity and rigidity of the compression spring.
