Definitions

  • a pair of pliers is a two-legged tool in which the action points press against each other.
  • Pliers basically consist of three components, namely the handles, the joint and the pliers head. They work according to the leverage principle. Two two-sided levers are connected by a joint.

According to the law of leverage, the force applied to the handles hand force is amplified and transmitted by means of the pliers head on a workpiece.
  • Pliers as they are the basis of this invention are manifold, especially used as a water pump pliers.
  • Water pump pliers are grippers with adjustable sliding joint, so that different opening widths of the mouth can be adjusted. They are mainly used for gripping pipes, sleeves and screws / nuts of various types, but also of flat material etc.

  • the second tong arm can be adjusted with the second jaw for coarse adjustment in the locking slot. By operating the pliers, the second forceps jaw is displaced according to the lever travel along the power transmission portion.
  • the known pliers have the disadvantage that they have many places where a user can clamp, for example, during coarse placement of the pliers and when accessing.
  • the EP 0 116 305 A1 describes a water pump pliers with two by a hinge pin pivotally interconnected pliers legs.
  • Each pliers leg has a jaw at one end, while at the other end a handle portion is provided.
  • the respective forceps jaw is formed in one piece with the corresponding pliers limb and thus immovably relative to the pliers limb.
  • the hinge pin is guided in a bore of a pliers leg and engages with a toothed portion in a correspondingly profiled longitudinal slot of the other pliers limb.
  • the hinge pin can be moved against a leaf spring in the direction of the bore, wherein the tooth portion emerges from the longitudinal slot and thus a decoupling of the pliers legs is achieved.

Aus der europäischen Patentschrift EP 0 421 107 B1 ist eine Schlüsselzange bekannt. In dieser Druckschrift wird eine Schlüsselzange mit zwei das Zangenmaul bildenden Zangenbacken beschrieben. Von den Zangenbacken sitzt die eine fest an einem Zangenschenkel, welcher zu Grobverstellung des Zangenmaules eine Längsschlitzführung für einen Zangenschenkel-Drehzapfen aufweist. Eine gabelförmige, bewegliche Backe zum Umgreifen des feststehenden Zangenschenkels wird verschiebbar in einer Führungsnut an dem die feste Zangenbacke tragenden Zangenschenkel geführt. Eine Kraftübertragungsstelle zwischen einer Schulter der verschiebbaren Zangenbacke und dem backenseitigen Arm des beweglichen Zangenschenkels ist zur Zangenmaulschließung verlagerbar. Die als formschlüssiger Eingriff zwischen backenseitigem Arm und bewegbarer Zangenbacke gestaltete Kraftübertragungsstelle ist die Verbindungsstelle sowohl zur Groblängsverstellung als auch zur Zangenmaulschließung zwischen Zangenschenkel und beweglicher Backe.From the European patent EP 0 421 107 B1 is known a key pliers. In this document, a pair of pliers with two forceps jaws forming pliers jaws is described. Of the forceps jaws one sits firmly on a pliers leg, which has a longitudinal slot guide for a pliers leg pivot to coarse adjustment of the pliers mouth. A fork-shaped, movable jaw for gripping around the fixed pliers limb is displaceably guided in a guide groove on the forceps jaw supporting the fixed pliers jaw. A force transmission point between a shoulder of the displaceable jaw and the jaw-side arm of the movable forceps leg is displaceable for tongs mouth closure. Designed as a positive engagement between backenseitigem arm and movable jaw force transfer point is the connection point for both the coarse longitudinal adjustment and the pliers mouth closure between pliers legs and movable jaw.

Eine zweite Zangenbacke ist verschiebbar auf dem ersten Zangenarm einseitig angeordnet.The US patent US 3,534,641 discloses a forceps consisting of two forceps arms. On the first tong arm a first jaw is firmly formed. A second jaw is slidably disposed on the first gun arm on one side.

Dazu weist der erste Zangenarm einen Abschnitt mit einer zur Zangenschwenkachse senkrechten Auflagefläche auf. Die zweite Zangenbacke ist so ausgebildet, dass sie die Auflagefläche des ersten Zangenarms mit einer nutenförmigen Anlagefläche umgreift. In dem ersten Zangenarm ist ferner ein Rastschlitz vorgesehen, in dem ein als Schraube ausgebildeter Gelenkzapfen mit einem Rastmechanismus angeordnet ist. Der zweite Zangenarm greift an diesem Gelenkzapfen in die zweite bewegliche Zangenbacke zur Kraftübertragung ein. Während der zweite Zangenarm dabei an der einen Seite des ersten Zangenarms angeordnet ist, ist die zweite Zangenbacke entsprechend auf der entgegengesetzten Seite des ersten Zangenarms vorgesehen. Der zweite Zangenarm kann mit der zweiten Zangenbacke zur Grobverstellung in dem Rastschlitz verstellt werden. Durch die Betätigung der Zange wird die zweite Zangenbacke entsprechend dem Hebelweg entlang des Abschnitts zur Kraftübertragung verschoben.For this purpose, the first gun arm has a section with a support surface perpendicular to the tong pivot axis. The second jaw is designed so that it engages around the support surface of the first gun arm with a groove-shaped contact surface. In the first gun arm a locking slot is further provided, in which a screw designed as a pivot pin is arranged with a locking mechanism. The second tong arm engages this pivot pin in the second movable jaw for power transmission. While the second forceps arm is arranged on one side of the first forceps arm, the second forceps jaw is correspondingly provided on the opposite side of the first forceps arm. The second tong arm can be adjusted with the second jaw for coarse adjustment in the locking slot. By operating the pliers, the second forceps jaw is displaced according to the lever travel along the power transmission portion.

Die bekannten Zangen haben den Nachteil, dass sie über viele Stellen verfügen, an denen sich ein Nutzer beispielsweise beim Grobeinstellen der Zange und beim Zugreifen klemmen kann.The known pliers have the disadvantage that they have many places where a user can clamp, for example, during coarse placement of the pliers and when accessing.

DieThe EP 0 116 305 A1EP 0 116 305 A1 beschreibt eine Wasserpumpenzange mit zwei durch einen Gelenkbolzen schwenkbar miteinander verbundene Zangenschenkel. Jeder Zangenschenkel verfügt an einem Ende über eine Zangenbacke, während am anderen Ende ein Griffabschnitt vorgesehen ist. Dabei ist die jeweilige Zangenbacke in einem Stück mit dem entsprechenden Zangenschenkel und somit unbeweglich gegenüber dem Zangenschenkel ausgebildet. Der Gelenkbolzen wird in einer Bohrung des einen Zangenschenkels geführt und greift mit einem verzahnten Abschnitt in einen entsprechend profilierten Längsschlitz des anderen Zangenschenkels ein. Zum Verstellen der Maulgröße lässt sich der Gelenkbolzen gegen eine Blattfeder in Richtung der Bohrung verschieben, wobei der Zahnabschnitt aus dem Längsschlitz austritt und somit eine Entkopplung der Zangenschenkel erreicht wird. Der Gelenkbolzen wird auch im entkuppelten Zustand undrehbar gegenüber dem Längsschlitz gehalten.describes a water pump pliers with two by a hinge pin pivotally interconnected pliers legs. Each pliers leg has a jaw at one end, while at the other end a handle portion is provided. In this case, the respective forceps jaw is formed in one piece with the corresponding pliers limb and thus immovably relative to the pliers limb. The hinge pin is guided in a bore of a pliers leg and engages with a toothed portion in a correspondingly profiled longitudinal slot of the other pliers limb. To adjust the mouth size, the hinge pin can be moved against a leaf spring in the direction of the bore, wherein the tooth portion emerges from the longitudinal slot and thus a decoupling of the pliers legs is achieved. The hinge pin is held in the uncoupled state non-rotatable relative to the longitudinal slot.

Offenbarung der ErfindungDisclosure of the invention

Aufgabe der Erfindung ist es daher, die bekannten Zangen fortzubilden und dem gegenüber besseren Schutz vor Verletzungen dem Nutzer zu geben.The object of the invention is therefore to train the known pliers and to give the better protection against injury to the user.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass bei einer Zange mit veränderbarer Maulweite, insbesondere Wasserpumpenzange, mit einem ersten und einem zweiten Zangenarm, die um einen Schwenkzapfen schwenkbar miteinander verbunden sind, der eingangs genannten Art,

  • e) die Zwangsführung für die bewegliche Zangenbacke gebildet wird durch
    • einen Längsschlitz durch den ersten Zangenarm, in dem der zweite Zangenarm und eine an die bewegliche Zangenbacke angeformte und durch den Längsschlitz ragende Führungsnase geführt sind,
    • zwei zur Zangenschwenkachse parallele und seitlich am ersten Zangenarm gegenüberliegende, den Längsschlitz jeweils umgebende plane Auflageflächen,
    • eine entsprechende plane Anlagefläche an der zum Längsschlitz zeigenden Seite der beweglichen Zangenbacke, sowie
    • eine entsprechende gegenüberliegende plane, zur Auflagerfläche des ersten Zangenarms zeigende Anlagefläche an einem knopfartigen Vorsprung des aus dem Längsschlitz herausragenden Endes der Führungsnase.
According to the invention the object is achieved in that in a pliers with variable mouth width, in particular water pump pliers, with a first and a second gun arm, which are pivotally connected to each other about a pivot pin, of the aforementioned type,
  • e) the positive guide for the movable jaw is formed by
    • a longitudinal slot through the first tong arm, in which the second tong arm and an integrally formed on the movable forceps jaw and projecting through the longitudinal slot guide nose are guided,
    • two plane contact surfaces parallel to the clamp pivot axis and laterally opposite the first clamp arm, the longitudinal slot respectively surrounding the longitudinal slot ,
    • a corresponding plane bearing surface on the side facing the longitudinal slot side of the movable jaw, and
    • a corresponding opposite planar, the support surface of the first gun arm pointing contact surface on a button-like projection of the protruding from the longitudinal slot end of the guide lug.

Die Erfindung beruht auf dem Prinzip die Zwangsführung so auszugestalten, dass die Führung der beweglichen Zangenbacke weitestgehend geschützt verläuft. Dies wird insbesondere dadurch erreicht, dass der zweite Zangenarm und die bewegliche Zangenbacke in einem Längsschlitz geführt werden, der den Nutzer vor Klemmverletzungen weitestgehend bewahrt. Der Längsschlitz verdeckt, soweit wie möglich, die Teile der Zange, an denen sich ein Nutzer, besonders beim Einstellen der Zange, verletzen könnte. Weiterhin wird die Zwangsführung in Bereiche verlagert, die beim Einstellen und bei der Betätigung der Zange nicht in Kontakt mit dem Nutzer kommt.The invention is based on the principle of designing the positive guidance in such a way that the guidance of the movable forceps jaw runs as far as possible protected. This is achieved in particular by guiding the second tong arm and the movable forceps jaw in a longitudinal slot, which largely protects the user against jamming injuries. The longitudinal slot conceals, as far as possible, the parts of the forceps that could injure a user, especially when adjusting the forceps. Furthermore, the forced operation is shifted into areas that do not come into contact with the user when setting and when operating the pliers.

Als vorteilhafte Ausgestaltung der Erfindung hat sich erwiesen, wenn der Schwenkzapfen der erfindungsgemäßen Zange in einem zur Zwangsführung parallelen Schlitz geführt wird. Durch diese Maßnahme wird durch eine gleichmäßige Kraftverteilung eine zusätzliche Stabilität der Zange erreicht.As an advantageous embodiment of the invention has been found, when the pivot pin of the pliers according to the invention is guided in a slot parallel to the positive guide. By this measure, an additional stability of the pliers is achieved by a uniform force distribution.

Gemäß einer bevorzugten Variante der erfindungsgemäßen Zange ist der Rastmechanismus aus dem zur Zwangsführung parallelen Schlitz und aus wenigstens einem an dem Schwenkzapfen vorgesehenen Rastzahn gebildet. Damit die Zange grob eingestellt werden kann, wird die Zange grob auf eine geeignete Maulweite verstellt. Die Verstellung wird durch Verschieben des Schwenkzapfens in dem zur Zwangsführung parallelen Schlitz vorgenommen. Der Rastzahn trägt dazu bei, dass der Schwenkzapfen in einer Stellung, beispielsweise durch Verkeilung, festgestellt werden kann. Vorzugsweise verfügt der zur Zwangsführung parallele Schlitz über eine Verzahnung zum Einrasten des Rastzahns, welche den Rastmechanismus stabilisiert.According to a preferred variant of the pliers according to the invention, the latching mechanism is formed from the slot parallel to the positive guide and from at least one latching tooth provided on the pivot pin. To make the pliers coarse, the pliers are roughly adjusted to a suitable jaw width. The adjustment is made by moving the pivot pin in the slot parallel to the forced operation. The locking tooth contributes to the pivot pin in a position, for example by wedging, can be determined. Preferably, the slot parallel to the positive guide has a toothing for locking the latching tooth, which stabilizes the latching mechanism.

Ferner wird die erfindungsgemäße Zange vorteilhaft ausgestaltet, indem der Rastmechanismus auf zwei gegenüberliegenden Seiten des Längsschlitzes vorgesehen ist. Durch diese Maßnahme wird zusätzlich erreicht, dass die Kraft nicht einseitig auf eine Längsschlitzseite verteilt wird, sondern symmetrisch auf beide gegenüberliegende Längsschlitzseiten. Bei einem einseitigen Ratmechanismus wird die Kraft auf eine Seite des Längsschlitzes geleitet, was bei starker Beanspruchung wegen der Unsymmetrie zu Verformungen führen kann. Durch die symmetrische Anordnung findet eine gleichmäßige Beanspruchung der Zange statt, was zu einer erhöhten Lebensdauer der Zange führen kann.Furthermore, the forceps of the invention is advantageously designed by the locking mechanism is provided on two opposite sides of the longitudinal slot. By this measure is additionally achieved that the force is not distributed unilaterally on a longitudinal slot side, but symmetrically on both opposite longitudinal slot sides. In a one-sided Ratmechanismus the force is directed to one side of the longitudinal slot, which can lead to deformations under heavy use due to the imbalance. Due to the symmetrical arrangement, a uniform loading of the pliers takes place, which can lead to an increased life of the pliers.

Weiterhin ist gemäß einer vorteilhaften Ausgestaltung der Erfindung der Rastmechanismus mit einer Feder vorgespannt. Damit kann der Rastmechanismus sich nicht ohne weiteres aus seiner Stellung lösen. Um die Zange für die Grobeinstellung zu verstellen ist somit immer erforderlich, den Rastmechanismus gegen eine Federkraft zu entriegeln. Der Nutzer des Werkzeugs kann sich demnach nicht mehr so leicht verletzen, weil sich bei der Betätigung der Rastmechanismus versehentlich selbständig löst, wodurch es zu Klemmungen oder zum Abrutschen der Zange kommen kann.Furthermore, according to an advantageous embodiment of the invention, the latching mechanism is biased by a spring. Thus, the locking mechanism can not easily be released from its position. To adjust the pliers for coarse adjustment is thus always required to unlock the latching mechanism against a spring force. The user of the tool can therefore no longer hurt so easily, because inadvertently loosens upon actuation of the locking mechanism automatically, which can lead to jamming or slipping of the pliers.

Vorteilhaft wirkt sich bei der erfindungsgemäßen Zange ferner aus, dass das Gelenk zwischen dem zweiten Zangenarm und der zweite bewegliche Zangenbacke durch einen am Ende des zweiten Zangenarms angeformten schulterförmigen Vorsprung, der in eine geeignete Ausnehmung der zweiten Zangenbacke zur Kraftübertragung eingreift, gebildet wird. Durch diese Maßnahme erhält man ein einfach herzustellendes Gelenk, welches den Anforderungen für die Kraftübertragung genügt.Advantageously, in the case of the forceps according to the invention, the joint between the second forceps arm and the second movable forceps jaw is formed by a shoulder-shaped projection integrally formed on the end of the second forceps arm and engaging in a suitable recess of the second forceps jaw. By this measure, one obtains a simple-to-produce joint, which meets the requirements for power transmission.

Eine bevorzugte Variante der erfindungsgemäßen Zange ergibt sich schließlich, wenn das Gelenk zwischen dem zweiten Zangenarm und der zweiten beweglichen Zangenbacke durch Schutzmittel nach außen verdeckt ist. Beispielsweise durch eine Schutzhülle wird nicht nur vermieden, dass Schmutz in das Gelenk eindringt, sondern auch dass ein Bereich geschützt wird, in dem ein Zangennutzer sich klemmen könnte Weitere Vorteile ergeben sich aus dem Gegenstand der Unteransprüche, sowie den Zeichnungen mit den dazugehörigen Beschreibungen.A preferred variant of the forceps according to the invention finally results when the joint between the second forceps arm and the second movable forceps jaw is covered by protective means to the outside. For example, by a protective sheath not only prevents dirt from entering the joint, but also that an area is protected in which a pliers user could get stuck Further advantages emerge from the subject matter of the subclaims, as well as the drawings with the associated descriptions.

Bevorzugtes AusführungsbeispielPreferred embodiment

In Fig. 1 wird in einer schematischen Prinzipskizze eine erfindungsgemäße Zange 10 in Seitenansicht dargestellt. Die Zange 10 weist einen ersten Zangenarm 12 und einen zweiten Zangenarm 14 auf. Jeder Zangenarm 12, 14 verfügt an einem Griffende 16, 18 über einen Handgriff 20, 22. An dem griffseitig abgewandten Ende 24 des ersten Zangenarms 12 ist eine erste Zangenbacke 26 fest angeformt. Der zweite Zangenarm 14 ist um einen Schwenkzapfen 28 schwenkbar mit dem ersten Zangenarm 12 verbunden. Über den Schwenkzapfen 28 wird eine Schwenkachse 29 definiert, siehe auch Fig. 3.In Fig. 1 a tongs 10 according to the invention is shown in side view in a schematic schematic diagram. The forceps 10 has a first forceps arm 12 and a second forceps arm 14. Each tong arm 12, 14 has at a handle end 16, 18 via a handle 20, 22. At the handle side facing away from the end 24 of the first gun arm 12, a first jaw 26 is firmly formed. The second tong arm 14 is pivotally connected to the first tong arm 12 about a pivot pin 28. About the pivot pin 28, a pivot axis 29 is defined, see also Fig. 3 ,

Eine zweite Zangenbacke 30 ist in einem Abschnitt 32 des ersten Zangenarms 12 verschiebbar angeordnet. Über ein Gelenk 34 sind der zweite Zangenarm 14 und die zweite Zangenbacke 30 miteinander beweglich gekoppelt. Das Gelenk 34 besteht, wie in Fig. 2 deutlich wird, aus einer Ausnehmung 36 und einer einen am griffseitig abgewandten Ende 38 des zweiten Zangenarms 14 angeformten schulterförmigen Vorsprung 40.A second forceps jaw 30 is slidably disposed in a portion 32 of the first forceps arm 12. About a hinge 34, the second gun arm 14 and the second jaw 30 are movably coupled to each other. The joint 34 consists, as in Fig. 2 becomes clear, from a recess 36 and an on the handle side remote end 38 of the second gun arm 14 integrally formed shoulder-shaped projection 40th

Der erste Zangenarm 12 verfügt in dem Abschnitt 32 über einen zur Schwenkachse 29 senkrechten Längsschlitz 42. Durch diesen Längsschlitz 42 sind der zweite Zangenarm 14 und eine an die zweite Zangenbacke 30 angeformte Führungsnase 44 geführt.The first tong arm 12 has in the section 32 via a longitudinal slot 42 perpendicular to the pivot axis 29. Through this longitudinal slot 42, the second gun arm 14 and an integrally formed on the second jaw 30 guide nose 44 are guided.

Der erste Zangenarm 12 verfügt ferner über einen Rastmechanismus 46. Der Rastmechanismus 46 wird aus dem Schwenkzapfen 28 und zwei Rastschlitzen 48, 50 gebildet. Die beiden Rastschlitze 48, 50 befinden sich dazu jeweils auf gegenüberliegenden Seiten 52, 54 des Längsschlitzes 42. Die Rastschlitze 48, 50 weisen jeweils eine Verzahnung 56, 58 auf, in die eine Rastzahnanordnung 60 zum Rasten einrastet. Die Rastzahnanordnung 60 ist dazu federbelastet an dem Schwenkzapfen 28 vorgesehen. Um eine Grobeinstellung der Zange 10 vornehmen zu können wird die Rastzahnanordnung 60 aus der Verzahnung 56, 58 gegen die Federkraft mit einem geeignet vorgesehenen Druckknopf 59 herausbewegt. Der Schwenkzapfen 28 lässt sich dann mit dem zweiten Zangenarm 14 und der zweiten beweglichen Zangenbacke 30 innerhalb der Rastschlitze 48, 50 verschieben. Durch die Rückstellkraft der Feder 74 wird die Rastzahnanordnung 60 des Schwenkzapfens 28 wieder in die Verzahnung 56, 58 der Rastschlitze 48, 50 zurückgesetzt. Auf diese Weise lässt sich eine gewünschte Grobstellung des zweiten Zangenarms 14 gegenüber dem ersten Zangenarm 12 verwirklichen.The first gun arm 12 also has a detent mechanism 46. The detent mechanism 46 is formed from the pivot pin 28 and two detent slots 48, 50. For this purpose, the two latching slots 48, 50 are respectively located on opposite sides 52, 54 of the longitudinal slot 42. The latching slots 48, 50 each have a toothing 56, 58 into which a latching tooth arrangement 60 engages for latching. The latching tooth arrangement 60 is provided spring-loaded on the pivot pin 28. In order to make a coarse adjustment of the forceps 10, the locking tooth arrangement 60 is moved out of the toothing 56, 58 against the spring force with a suitably provided push button 59. The pivot pin 28 can then be moved with the second gun arm 14 and the second movable jaw 30 within the locking slots 48, 50. Due to the restoring force of the spring 74, the latching tooth arrangement 60 of the pivot pin 28 is returned to the toothing 56, 58 of the latching slots 48, 50. In this way, a desired coarse adjustment of the second tong arm 14 relative to the first tong arm 12 can be realized.

Der Längsschlitz 42 des ersten Zangenarms 12 verfügt über zwei gegenüberliegende Auflageflächen 62, 64. Die Auflageflächen 62, 64 sind parallel zur Schwenkachse 29 und parallel zu den Rastschlitzen 48, 50 angeordnet. Die an der Vorder- und Rückseite des ersten Zangenarms 12 vorgesehenen planen Auflageflächen 62, 64 umgeben auf ihrer Seite jeweils den Längsschlitz 42. Die zweite bewegliche Zangenbacke 30 verfügt an ihrer zum Längsschlitz 42 zeigenden Seite über eine als Vorsprung ausgebildete erste Anlagefläche 66. Die durch den Längsschlitz 42 ragende Führungsnase 44 verfügt entsprechend über zweite Anlagefläche 68, welche ebenfalls als knopfartiger Vorsprung 69 ausgebildet ist. Die Anlagefläche 68 zeigt zu der Auflagefläche 64.The longitudinal slot 42 of the first gun arm 12 has two opposite bearing surfaces 62, 64. The bearing surfaces 62, 64 are arranged parallel to the pivot axis 29 and parallel to the locking slots 48, 50. The provided on the front and back of the first gun arm 12 flat bearing surfaces 62, 64 surround on their side in each case the longitudinal slot 42. The second movable jaw 30 has on its side facing the longitudinal slot 42 via a trained as a projection first contact surface 66th Die durch The longitudinal slot 42 projecting guide nose 44 has correspondingly second contact surface 68, which is also designed as a button-like projection 69. The contact surface 68 points to the bearing surface 64.

Die Auflageflächen 62, 64 bilden gemeinsam mit Anlagenflächen 66, 68 eine Zwangsführung 70. Die Zwangsführung 70 lässt die beweglichen zweiten Zangenbacke 30 nur entlang der Auflageflächen 62, 64, wie auf einer Schiene, gleiten.The support surfaces 62, 64 together with contact surfaces 66, 68 form a positive guide 70. The positive guide 70 allows the movable second jaw 30 to slide only along the support surfaces 62, 64, as on a rail.

In Fig. 1 mit einem Kreis 72 ein Bereich gekennzeichnete, der in Fig. 2 vergrößert dargestellt ist. Ein Teil des Abschnitts 32 wird in dieser Abbildung mit einem Teil der zusammengedrückten Zangenbacken 26, 30 gezeigt. Die zweite bewegliche Zangenbacke 30 zeigt hier die angeformte Führungnase 44, welche durch den Längsschlitz 42 geführt ist. An der Führungnase 44 ist an dem einen, aus dem Längsschlitz 42 herausragenden Ende, die Anlagefläche 68 als knopfartiger Vorsprung 69 zu sehen. Die Anlagefläche 66 und die Anlagefläche 68 führen die zweite bewegliche Zangenbacke 30 entlang der Auflageflächen 62, 64 im Abschnitt 32 des ersten Zangenarms 12.

A portion of section 32 is shown in this figure with a portion of the compressed jaws 26, 30. The second movable jaw 30 here shows the molded guide nose 44, which is guided through the longitudinal slot 42. On the guide nose 44, the contact surface 68 can be seen as a button-like projection 69 on the one, protruding from the longitudinal slot 42 end. The contact surface 66 and the abutment surface 68 guide the second movable forceps jaw 30 along the bearing surfaces 62, 64 in the portion 32 of the first forceps arm 12. In this case, the second forceps jaw 30 is supported by the positive guide 70 thus formed.

Die Zangenarme 12, 14 werden um den Schwenkzapfen 28 zum Aufbringen einer Hebelkraft, die auf die Zangenbacken 26, 30 wirkt, geschwenkt. Der zweite Zangenarm 14 greift dazu in die Gelenkverbindung 34, die aus dem angeformten schulterförmigen Vorsprung 40 und der Ausnehmung 36 besteht. Die zweite Zangenbacke 30 wird nur entlang der Zwangsführung 70 bei Betätigung des Werkzeugs geführt. Das Gelenk 34 benötigt dazu ein entsprechendes Spiel in der Ausnehmung 36, damit diese Bewegungen vollzogen werden kann. Die Ausnehmungen 36 ist normalerweise nicht sichtbar und nach außen hin verdeckt, damit insbesondere Klemmverletzungen und Verschmutzungen vermieden werden.The pliers arms 12, 14 are pivoted about the pivot pin 28 for applying a leverage force acting on the pliers jaws 26, 30. The second gun arm 14 engages in the articulated connection 34, which consists of the integrally formed shoulder-shaped projection 40 and the recess 36. The second jaw 30 is guided only along the positive guide 70 upon actuation of the tool. The joint 34 requires a corresponding game in the recess 36 so that these movements can be completed. The recesses 36 is normally not visible and hidden from the outside, so that in particular clamping injuries and soiling can be avoided.
