摘要： The invention relates to a hand pliers for assembly purposes, more particularly for the assembly of pipe connections at pipe systems, the pliers comprised of two limbs which are rotatably connected to one another via a first link joint (1) and which by means of this link joint (1) are divided into an assembly limb and a handle limb (2,3), wherein the first handle limb (3) is divided into an off-handle lever (14) and into a handle-near lever (15) and wherein these two levers (14, 15) are rotatably connected to one another by means of a bolt (16) via a second link joint, wherein a tension wheel (17) and a ratchet wheel (18) with external toothing (27) connected torsionally proof to it are pivotably arranged on the bolt side by side (16) in axial direction, and wherein the tension wheel (17) engages into a tension means (20) that connects both handle limbs (2,3) to one another, and wherein a spring-loaded dog ratchet (25) is arranged at the handle-near lever (15), the dog ratchet engaging into the ratchet wheel (18) in such a manner that when the handle-near lever (15) makes a latching movement the ratchet wheel (18) and the tension wheel (17) execute a rotation that causes the closing of the pliers, with a spring-loaded arrest ratchet (30) being provided for which also engages in the ratchet wheel (18) and permits a rotation of the ratchet wheel (18) on closing the pliers, but which prevents its rotation in the opposite direction. It is the object of the present invention to provide a hand pliers whose arrest ratchet can be released even if subjected to great assembly forces. To solve this task the invention proposes a switch (33) by the actuation of which the direction of the spring loading of the arrest ratchet (30) is reversible in such a manner that the actuation of the switch (33) takes the effect that the engagement of the arrest ratchet (30) into the ratchet wheel (18) is abolished.
