PURPOSE: A telescopic suppression bar having an outer diameter gradually expanded is provided to apply big shock during beating by gradually expending external diameter. CONSTITUTION: A telescopic suppression bar having an outer diameter gradually expanded comprises a handle(1), a base bar(12), a multi-stage forming unit(10), an outermost rod(18), and an end stopper. The base bar is combined with the handle. The multi-stage forming unit is composed of one or more rods(14,16). The rods are successively connected from the base bar. The internal diameter of the center of the outer rod is bigger than external diameter of the center of the inner rod. The internal diameter of one end of each rod is smaller than the center and the external diameter of the other end of the rod is wider than the center. |
