ABSTRACT:
A shock suppressor has at least two sliding units stacked in an alternate manner, and each sliding unit consists of a moving base, a connecting base and at least one rod. The connecting base is moveably combined with the moving base via the at least one rod. At least one positioning hole and at least one curved guiding channel are defined respectively in the connecting base and moving base for the at least one rod to be mounted respectively in the at least one positioning hole and to extend moveably into a corresponding one of the at least one guiding channel. Accordingly, the shock suppressor can reduce or isolate the transmission of a shock efficiently.
