When the hydraulic breaker is working, it is usually subjected to a strong impact load, which acts on the chisel of the
breaker, and then acts on the inner bush of the breaker. The drill rod will continue to rub against the inner wall and the
rear step in the inner bush, and continuously produce impact loads on them. Also the inner wall and the rear step are
easily worn or damaged, so the inner outer bush protects the chisel.
