DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(15) As seen in FIGS. 1-3, the main joint is a pivotal connection that is connected to a right jaw 33 and a left jaw 34. The right jaw 33 and the left jaw 34 cooperate to grasp an object. The right jaw 33 is integrally formed and moves with a left jaw lever 36. Similarly, the left jaw 34 is integrally formed and moves with the right jaw lever 35. Thus, the main joint operates as a normal pair of pliers that connects the right and left jaw members.

(16) The compound portion is implemented with the auxiliary joint 22. The auxiliary joint 22 provides a joint between the right handle joint lever 37 and the left handle joint lever 38. A right handle 31 extends from the right handle joint lever 37 and is rigidly connected to the right handle joint lever 37. Similarly, a left handle 32 is rigidly connected to the left handle joint lever 38 and extends from the left handle joint lever 38. The left handle joint lever 38 and the right handle joint lever 37 are hinged at the auxiliary joint 22.

(17) The left handle joint lever 38 and the right handle joint lever 37 are also hinged to form a four bar mechanism. The left handle joint lever 38 is hinged to the left jaw lever 36 at the left handle joint 24. Similarly, the right jaw lever 35 is hinged to the right handle joint lever 37 at the right handle joint 23.

(18) The right handle joint lever 37 includes an indentation, namely the right handle indent 41. The auxiliary joint 22 is formed on an auxiliary joint protrusion 42, which protrudes into the right handle indent 41. The right handle indent 41 is rounded and receives a rounded portion of the auxiliary joint protrusion 42.

(19) The right handle indent 41 is formed in a pair including an upper right handle indent 141 above a lower right handle indent 241. Similarly, the auxiliary joint protrusion 42 is formed in a pair including an upper auxiliary joint protrusion 142 and a lower auxiliary joint protrusion 242. The pair of right handle indents 41 extend into the pair of auxiliary joint protrusions 42. The pair of right handle indent 41 are centered below the main joint 21. The pair of auxiliary joint protrusions 42 extend toward and away from each other during motion of the pliers handles.

(20) The upper auxiliary joint protrusion 142 is on a first level 43 and the lower auxiliary joint protrusion 241 is on a second level 44 below the upper auxiliary joint protrusion 141. The first level 43 is the upper level and the second level 44 is the lower level. When the pair of pliers is flipped, the upper level becomes the lower level and the lower level becomes the upper level. Because the pair of pliers is symmetrical when rotated, the configuration remains the same after rotation. The upper right handle indent 141 opposes the lower right handle indent 241. The upper right handle indent 141 is formed on the right jaw lever 35 and the lower right handle indent 241 is formed on the left jaw lever 36.

(21) The pair of pliers is constructed in an upper layer and a lower layer. The upper layer 43 is above the lower layer 44. The right handle joint lever 37 is formed on the lower layer and is connected to the left handle joint lever 38 which is on the upper layer. Similarly, the right jaw lever 35 is formed on the upper layer and is pivotally connected to the left jaw lever 36 formed on the lower layer because the main joint 21 connects the upper layer to the lower layer. The right jaw lever 35 is formed on the upper layer and is pivotally connected to the right handle joint lever 37 on the lower layer because the right handle joint 23 connects the upper layer to the lower layer. The left handle joint lever 38 is formed on the upper layer and pivotally connected to the left jaw lever 36 because the left handle joint 24 connects the upper layer to the lower layer. Finally, the left handle joint lever 38 formed on the upper layer is pivotally connected to the right handle joint lever 37 formed on the lower layer because the auxiliary joint 22 connects the upper layer to the lower layer.
