Force Amplified Fastener for Power Tool Implements

A method for removably coupling a detachable implement to a power tool, the method comprising:

• interfacing a force amplified fastener assembly with a shaft of the power tool, wherein the force amplified fastener assembly includes a top housing, a bottom structure, a fastening element, a force amplifying gear train, and a lock mechanism, wherein the top housing and bottom structure are configured to nest and provide an enclosed area for housing one or more components of the force amplified fastener assembly, wherein the fastening element is disposed between the top housing and the bottom structure and at least partially within the enclosed area, wherein the fastening element is configured for engagement with a shaft of the power tool, wherein the force amplifying gear train comprises a plurality of gears and at least one gear plate disposed in the enclosed area and in mechanical communication with the top housing, the bottom structure, and the fastening element, wherein the force amplifying gear train provides a mechanical advantage with respect to application of torque to the fastening element in response to torque applied to the top housing, and wherein the lock mechanism is disposed at least partially within the enclosed area and is operative to discourage rotation of the top housing relative to the gear plate in at least a loosening direction;
• engaging a first lock element of the lock mechanism and causing a second lock element of the lock mechanism to enter an unlocked position configured to allow rotation of the top housing relative to the gear plate in the loosening direction;
• and
• applying torque in the loosening direction to the top housing and inducing torque at the fastening element in the loosening direction, wherein the rotation of the top housing relative to the gear plate causes the force amplifying gear train to provide a mechanical advantage with respect to the torque induced at the fastening element.

• and
• an exterior surface covering configured to provide a removable and replaceable protective surface for at least a portion of the force amplified fastener assembly.
