<p>A large capacity locking pliers (10) comprises a body (12), a fixed jaw (14) secured to the body (12) and comprising a first working surface (16). The locking pliers (10) define a jaw axis (J) extending between a pivot axis (28) and the first end part (18). The first concave inner portion (22) deviates from the jaw axis (J) by a maximum value equal to X and the second inner portion (38) deviates from the jaw axis (J) by a maximum value equal to Y. The ratio X/Y is less than 0.5. The first concave inner portion (22) extends over an angle alpha, which is at least 45 degrees. A second working surface (32) differs from the first working surface (16) as to the shape and contains the second concave inner portion (38) extends over an angle beta, which is at least 80 degrees and is greater than the angle alpha.</p> |
