Abstract
The invention relates to a pair of pliers (1) with two pliers legs (2, 3) crossing at a joint pin (4), one (3) of which legs is movable and the other (2) is fixed, and with a spring (13) between the fixed leg (2) and the joint pin (4) acting in such a way as to support interlocking engagement of the joint pin (4), wherein the pliers legs (2, 3) form gripping portions (5, 6) on one side of the joint pin (4) and a pliers mouth is formed on the other side of the joint pin (4), wherein furthermore the joint pin (4), through which a pivot axis (A) of the movable pliers leg at the same time extends, is adjustable in a longitudinal slot (9) of the fixed pliers leg (2), and wherein the movable pliers leg (3) can be optionally fixed in relation to the fixed pliers leg (2) by means of interlocking engagement between the joint pin (4) and the longitudinal slot (9) that takes place in the direction of a plane defined by the pliers legs (2, 3). To design and develop a pair of pliers of the type in question in such a way that different handling characteristics are advantageously obtained, it is proposed that the joint pin (4) is released from the interlock merely by tensile loading of the movabl…
