ABSTRACT:
A tool apparatus for applying a large closing force to an object is disclosed. The tool apparatus, capable of improving the efficiency and ease of effort required to crimp nuts onto bolts and to cut materials such as multi-strand cables, bars and the like, comprises first and second jaws, each having first and second portions. Each first portion has a linking end. A mechanism is provided for interconnecting the first and second jaws, and for providing a pivoting point for each of the first and second jaws. A hydraulic cylinder drives a rod linearly along a drive axis from a first position to a second position with a drive force. A scissor mechanism is provided for connecting the rod to the linking end of the first jaw and to the linking end of the second jaw, and for translating and multiplying the drive force to apply an opening force to each of the linking ends, whereby the first portions rotate from their closed position to their open position and the second portions rotate from their open position to their closed position to apply the closing force to the object.
