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.
