摘要

This patent relates to a method of assembling a spindle assembly comprising: a tubular spindle ( 2 ); a beat piece structure which is capable of being located and slid within a part ( 6 ) of the spindle ( 2 ); a stop mechanism ( 20 ) located within the spindle ( 2 ) which prevents the beat piece structure from sliding past it when the beat piece structure is located in and sliding within the spindle ( 2 ); and a retention mechanism capable of being located within the spindle ( 2 ) and which prevents the beat piece structure from sliding past it when the beat piece structure is located in and sliding within the spindle ( 2 ); wherein the method comprises the steps of: i) inserting the beat piece structure into the spindle through one end of the spindle and sliding it along the spindle ( 2 ) in one direction until it abuts the stop mechanism ( 20 ); ii) inserting the retention mechanism into the spindle through the same end of the spindle ( 2 ) until it locates at a predetermined position; iii) sliding the beat piece structure in the opposite direction away from the stop mechanism ( 20 ) until it abuts the retention mechanism 106. It also covers a spindle constructed by such a method.
