ABSTRACT:
A tool with a variable force transmission ratio between the handles, which receive the driving force, and the working jaws adapted to perform the desired work, comprising a first stationary working jaw and a second movable working jaw journalled in a first pivot point to the first jaw, having an elongated cam profile arranged beyond said first pivot point and with the exception of eventual adjustments fixedly connected with and extending essentially in the same direction as the first jaw, the second jaw being prolonged beyond said first pivot point by an extension to which an operative means for receiving the driving force is journalled in a second pivot point spaced from the first pivot point, which operative means is rigidly connected to contact means arranged in such a manner that when the operative means are actuated by a driving force the contact means is pressed against the cam profile and made to follow it.
