Abstract
Use of multiple-slope and/or multiple-offset mechanism or equivalent to address the issues with current mechanical clickers that have single-slope spring mechanism. The varying-slope can be a continuously varying-slope non-linear spring, or a combination of discretely varying multiple-slope springs. This inventior is useful for clicker type torque wrenches, clicker type torque screw drivers, beam type torque wrenches, beam type torque screw drivers and shock absorbers. The present invention is equally applicable to clickers that click in both the CW (clockwise) and CCW (counterclockwise) directions or clickers that click only in one direction. The invention is generally characterized by placing a non-linear spring or combination of springs in the tool body to achieve multiple slope operation rather than using one single slope spring.
