[0002] The action is one of the components of a grand piano. The adjusting knobs of the action are usually adjusted regularly or before use. Among them, during the internal adjustment of the grand piano's action system, the adjusting knobs of a conventional grand piano are adjusted by a cable tuning needle. Specifically, the cable tuning needle is inserted into the adjustment hole on the side of the adjusting knob, and then the cable tuning needle is rotated to change the height of the adjusting knob to determine the piano's disconnection distance. The adjusting knobs of the carbon plastic action are different from those of the conventional action. The adjusting knobs of the carbon plastic action are adjusted by turning a circular adjusting screw inserted on the top surface of the adjusting gear clockwise or counterclockwise. Therefore, the different adjusting knob structure makes it impossible to use a conventional cable tuning needle for adjustment. If a conventional cable tuning needle is used for adjustment, the action keyboard needs to be pulled out of the piano body before adjustment.
