Claims18
A pair of locking pliers comprising:
- a fixed handle;
- a fixed jaw fixedly connected to the fixed handle and including a first clamping surface, with the first clamping surface having a first edge and a second edge, with the second edge extending rearward from the first edge, with the first and second edges inclining toward each other, with the first edge including a plurality of asymmetrical first teeth extending therefrom, with each first tooth including a longer first profiled side and a shorter first profiled side, with the longer first profiled side extending along a first axis and inclined to the first edge at a first angle, and with the first angle in a range between 25 degrees and 45 degrees;
- a movable jaw cooperating with the fixed jaw, having a first joining end pivotally connected to the fixed handle, and including a second clamping surface, with the second clamping surface having a third edge and a fourth edge, with the fourth edge extending rearward from the third edge, with the third and fourth edges inclining toward each other, with the fourth edge including a plurality of asymmetrical second teeth extending therefrom, with each second tooth including a longer second profiled side and a shorter second profiled side, with the longer second profiled side extending along a second axis and inclined to the fourth edge at a second angle, and with the second angle in a range between 25 and 45 degrees;
- and
- a movable handle pivotally connected to a second joining end of the movable jaw;
- wherein the movable jaw is pivoted toward closer to the fixed jaw upon operating the pair of locking pliers from initial, locking, to tightening positions;
- and
- wherein the plurality of first teeth includes apexes thereof aligned along a third axis and the plurality of second teeth includes apexes thereof aligned along a fourth axis respectively, and wherein when the locking pliers is in the tightening position, the first and second axes intersect and include a first included angle of between 6 degrees and 20 degrees and the third and fourth axes intersect and have a second included angle of between 6 degrees and 20 degrees.
