Abstract
A hand tool includes a handle section having two L-shaped legs with a pulling leg attached to each handle leg. The handle legs are pivotally attached to each other by a pivot bolt and a pusher element is attached to that pivot bolt. As the handles are squeezed together, the pulling legs are moved in one direction and the pusher element is moved in an opposite direction. Thus, a moving the handles toward or away from each other generates simultaneous pushing and pulling forces. The pulling legs can be releasably or permanently attached to the handle, and an extension element can be releasably attached to the pushing element.

A hand tool for generating simultaneous pushing and pulling forces comprising:
- A) a handle unit that includes
- (1) two L-shaped handles, each having a long leg and a short leg and a heel located at one end of said short leg and a toe located at another end of said short leg;
- (2) a pivot bolt connecting one short leg to a second short leg at the toes of each of said short legs whereby movement of one long leg towards another long leg causes said short legs to pivot about said pivot bolt with respect to each other with one short leg moving clockwise about said pivot bolt and said second short leg moving counterclockwise about said pivot bolt and said heels and toes moving in opposite directions with respect to said pivot bolt when said handle long legs are moved toward or away from each other;
- B) a pushing element that includes a body having a proximal end connected to said pivot bolt and a distal end spaced from said pivot bolt, said pushing element body being forced longitudinally thereof in the direction of said handle unit toes when said handle unit handle long legs are moved toward or away from each other;
- C) two pulling legs, each pulling leg including a body having a proximal end attached to one of said heels to move therewith and a distal end spaced from said pushing element body distal end;
- D) an extension element and attaching means having threaded elements for releasably attaching said extension element to said pushing element;
- and
- E) mounting means for releasably mounting each of said pulling legs to an associated one of said holes, said mounting means including a slot defined through each heel with each slot including an arcuate opening on one end thereof and an arcuate section extending from said opening, said arcuate section having a width defined between walls on said heel, with said width being smaller than a diameter of said arcuate opening.
