Title: SELECTABLE ADVANTAGE LINKAGE MECHANISM FOR HAND OPERATED TOOLS
Abstract:
Disclosed herein is a tool operable through a hand squeezing force applied, in use of the tool, by an operator between handgrips of first and second handle members. The tool includes a first application member supported on the first handle member, a second application member supported for reciprocal displacement relative to the first application member, and a linkage mechanism coupling the second handle member to the second application member. The linkage mechanism includes a user selectable means for adjusting the mechanical advantage of force, in use, transferred from the handgrips to the application members.
