Parallel Jaws Locking Wrench/Plier

A parallel jaws locking wrench/pliers with toggle action, comprising:

• a. a body element being constructed with two body matching parts being bound together with screws,
• b. an outstanding “fixed jaw-post” being disposed upward from the right top corner of said body element,
• c. a channel, having a length equal to the width of said body element and being under said “fixed jaw-post”, being disposed between said body matching parts,
• d. a void, having a sufficient volume to allow the rocking movement of an action cam and the simultaneous translation movement of a left tapered bar and a right tapered bar, being formed between said body matching parts and being under and communicating with said channel,
• e. an outstanding “movable jaw-post” being integral of and being disposed upward from the “left midsection” of a movable part having cross sectional dimensions equal to those of said channel and being freely slidable in said channel,
• f. said left tapered bar and said right tapered bar being respectively extended vertically downward from the two respective ends of said movable part into said void, a right edge of said left tapered bar and a left edge of said right tapered bar being straight and parallel to each other, allowing an interface being freely slidable therebetween,
• g. a right side lower corner of said action cam being pivotally supported inside said void;
• a top corner of said action cam being pivotally connected with proper means to said movable part to effect the translational movement of said “movable jaw-post”;
• a left side lower corner of said action cam being pivotally connected to an upper pivotal hole of a locking lever,
• h. a handle being formed to have a cross section of channel shape and being securely attached to said body element with screws and it having a lower end being equipped with internal threads to accept an axially adjustable screw,
• i. a fulcrum bar having a lower end being kept constantly engaged with the upper end of said axially adjustable screw by a tension spring connected between said action cam and said handle,
• j. the lower pivot hole of said locking lever, the pivot hole of a releasing lever, and the pivot hole at the upper end of said fulcrum bar being journaled by one pivot,
• k. two outstanding elements being disposed close to the pivot of said releasing lever and to the respective opposite outside walls of said releasing lever,
• l. the upper end of a length of spring wire being anchored by the upper and the lower pivots of said locking lever, and
• m. the lower end of said spring wire being held against the releasing lever, preventing the releasing lever from unintentionally swinging out of the locking lever during operation.
