1. A sewing machine ankle assembly comprising:
an ankle comprising an upper portion and a lower portion, wherein the lower portion defines at least one structure configured to receive an attachment mechanism of a presser foot; and
a resilient member comprising an upper end and an opposing lower end, wherein the upper end is attached to the ankle, and wherein the lower end is positioned beneath a portion of the attachment mechanism of the presser foot when the attachment mechanism is received by the at least one structure of the ankle such that the lower portion of the resilient member exerts a force in a direction towards the at least one structure of the ankle for holding the portion of the attachment mechanism together with the at least one structure of the ankle; and
at least one pin that attaches the upper end of the resilient member to the upper portion of the ankle,
wherein the at least one structure of the ankle and the lower end of the resilient member form an opening that faces a substantially horizontal direction for receipt and release of the attachment mechanism of the presser foot along the substantially horizontal direction.
