Abstract:
1. An apparatus comprising: a rotary head assembly configured for attachment to a rotary power source, the rotary head assembly comprising wherein, when each retention member is configured so that the first and second retention member portions each have a diameter and are aligned along respective longitudinal axes, the diameter of the second retention member portion is larger than the diameter of the first retention member portion so that the retention member forms a T-shape; and wherein each retention member and respective biasing member are sized and configured so that, when the actuating external force is applied to the first retention member portion, the retention member is actuated causing the bias of the biasing member to be overcome and the second retention member portion to be removed from the respective slot, thereby releasing the respective retained member from the respective slot, wherein the retention member chamber defined by the rotary head housing comprises a first retention member chamber portion and a second retention member chamber portion and the rotary head housing further defines a sidewall at least semi-encircling the first face aperture, a top portion of the sidewall extending further from the first face than the first retention member portion when biased by the biasing member.
