Shock suppressor

Abstract

A shock suppressor has a first base, a second base, a sliding holder assembly and a connecting device. The second base is parallel to the first base. The connecting device is slidably mounted between the first base and second base to connect the first and second bases. The first base abuts against the connecting device in a curved contact surface to provide a first sliding mechanism in multiple directions. The second base abuts against the connecting device to provide a second sliding mechanism in a unidirection. The sliding holder assembly is mounted between the connecting device and at least one of the bases in a universal contacting manner.
