Multifunctional power driven positioning tool system

A multifunctional power driven positioning device comprising:

• a) a battery;
• b) a reversible motor powered by said battery;
• c) two upper spacer rods, two lower spacer rods, a removable base;
• a first connector means, an upper attachment connector means and a mechanical driven means driven by said motor;
• said first connector means removably and pivotally attaching said two lower spacer rods to said removable base;
• said upper attachment connector means removable and pivotally attaching said two upper spacer rods to a means to hold said two upper spacer rods a fixed distance apart relative to each other and said mechanical drive means acting to vary the distance between said two upper spacer rods and said two lower spacer rods;
• said mechanical drive means further comprising:
• 1) a first group of four bars pivotally connected to form a variable height quadrilateral arrangement pivotally connected at a top of said quadrilateral arrangement to a fist end of a first one of said two upper spacer rods and a bottom end of said quadrilateral arrangement pivotally connected to a first end of a first one of said two lower spacer rods;
• 2) a second group of four bars pivotally connected to form a second variable height arrangement pivotally connected at a top of said second arrangement to a second end of said first one of said two upper spacer rods and connected at a bottom end of said second arrangement to a second end of said first one of said two lower spacer rods;
• 3) a first upper drive arm pivotally connected at a first end to a first end of a second of said two upper spacer rods and pivotally connected at a second end to a midpoint of said first arrangement;
• a second upper drive arm pivotally connected at a first end to a second end of said second of said two upper spacer rods and pivotally connected of a second end to a mid-point of said second arrangement;
• 4) a first lower drive arm pivotally connected at a first end to a first end of a second of said two lower spacer rods and pivotally connected at a second end to a midpoint of said second arrangement;
• a second lower drive arm pivotally connected at a first end to a second end of said second of said two lower spacer rods and pivotally connected at a second end to a midpoint of said second arrangement;
• 5) a gearbox and a middle spacer rod, said middle spacer rod being pivotally connected between a first midpoint of said first and said second quadrilateral arrangement;
• and projections on said gearbox being pivotally connected between second midpoints of said first and said second arrangement;
• 6) a first and second threaded drive screw, dual limit switch means, and said gearbox cooperating with said motor and said middle spacer rods to vary the distance between said removable base and said upper attachment connector means to preset limits.
