Pliers actuation assembly group, pliers and method for assembling

Pliers comprising a pliers actuation assembly group with

• a) two hand levers, wherein
• aa) one hand lever has a first hand lever plate and a second hand lever plate which are rigidly connected to one another,
• ab) the other hand lever has a third hand lever plate and a fourth hand lever plate which are rigidly connected to one another, and
• ac) the first, second, third and fourth hand lever plates are arranged parallel to one another,
• b) a pivot bolt via which the hand levers are pivotably connected to one another,
• c) a stop formed by the first hand lever plate and a stop part held and/or guided on the third hand lever plate, the stop and the stop part coming into contact with one another to limit an opening angle of the hand levers,
• d) wherein at least one of the stop part and the pivot bolt has a shoulder which in the assembled state of the pliers actuation assembly group contacts the third hand lever plate for providing a support in a direction vertical to a pivot plane of the hand levers,
• the pliers actuation assembly group being coupled to a pliers head in such a way that a stroke of die halves of the pliers head can be brought about by means of a manual actuation of the pliers actuation assembly group.

A method of assembling a pliers actuator assembly group which can be coupled to a pliers head to form pliers in such a way that a stroke of die halves of the pliers head can be brought about by means of a manual actuation of the pliers actuation assembly group, the pliers actuator assembly group comprising

• a) two hand levers, wherein
• aa) one hand lever has a first hand lever plate and a second hand lever plate which are rigidly connected to one another,
• ab) the other hand lever has a third hand lever plate and a fourth hand lever plate which are rigidly connected to one another, and
• ac) the first, second, third and fourth hand lever plates are arranged parallel to one another,
• b) a pivot bolt via which the hand levers are pivotably connected to one another,
• c) a stop formed by the first hand lever plate and a stop part held and/or guided on the third hand lever plate, the stop and the stop part coming into contact with one another to limit an opening angle of the hand levers,
• d) wherein at least one of the stop part and the pivot bolt has a shoulder which in the assembled state of the pliers actuation assembly group contacts the third hand lever plate for providing a support in a direction vertical to a pivot plane of the hand levers,
• the method comprising the following method steps:
• inserting the pivot bolt into a bearing eye of the first hand lever plate;
• pushing the third hand lever plate onto the pivot bolt;
• inserting the stop part in such a way that a first longitudinal section extends into a recess or into an elongated hole of the first hand lever plate and through a holding and/or guiding bore of the third hand lever plate, the shoulder being supported on the third hand lever plate;
• pushing the second hand lever plate and the fourth hand lever plate onto the pivot bolt and blocking the support surface of a second longitudinal section of the stop part by the second hand lever plate or fourth hand lever plate from unwanted disassembly;
• fixing the first and second hand lever plates to each other and fixing the third and fourth hand lever plates to each other, whereby the pivot bolt and/or the stop part are trapped between two hand lever plates.
