Abstract
Systems and methods which provide force amplified fastener assemblies configured for use with respect to detachable implements for power tools are described. Force amplified fastener assemblies may implement various gear train configurations for giving a mechanical advantage with respect to manual manipulation of the fastener assembly. A force amplified fastener assembly may include a lock mechanism operative to lock and/or unlock the force amplified fastener assembly and thus a fastening element thereof. Force amplified fastener assemblies of embodiments of the inventions may be utilized in place of conventional lock nut for affixing detachable implements to power tools.
