Stripping pliers having two plier jaws

Abstract

The invention relates to a wire stripper (1) having two stripper jaws (2, 3), two outer clamping jaws (19, 20), two inner cutting jaws (22, 23) and two grips (4, 5), the cutting jaws (22, 23) being displaceable from a base position into an end position during the closing of the grips (4, 5), the cutting jaws (22, 23) further having in each case a cutting element (24, 25) having a cutting edge (32, 33), the cutting element (24, 25) being arranged such that the cutting edge (32, 33) of the cutting element (24, 25) is in contact with the clamping jaw (19, 20) of the clamping jaw (19, 20) of the clamping jaw (19, 20) of the clamping jaw (19, 20) of the clamping jaw (19, 20). The cutting edges (32, 33) are positioned relative to one another at a defined distance (a) in a defined position in which the cutting jaws (22, 23) are moved towards one another, the distance (a) being adjustable by means of an adjusting screw (38) in a position, which is regarded as a base position. In order to further improve the wire stripper of this type, it is proposed that the adjusting screw (38) is connected to an adjusting wheel (45), which can be aligned with a marking (46) for the basic position, which marking is fastened to one of the plier jaws (2, 3).

H02G 1 / 12 (2006.01) (54) Title of Invention: Wire Stripper with Two Jaws (57) Abstract: This invention relates to a wire stripper (1) having two jaws (2, 3), two outer clamping jaws (19, 20), two inner cutting jaws (22, 23), and two gripping parts (4, 5), wherein the cutting jaws (22, 23) can move from a basic position to a terminal position during the closing of the gripping parts (4, 5), wherein the cutting jaws (22, 23) also have cutting elements (24, 25) with cutting blades (32, 33), wherein the cutting blades (32, 33) are positioned relative to each other at a defined distance (a) in a defined position, wherein the cutting jaws (22, 23) move toward each other in the defined position, wherein the distance (a) in the position considered as the basic position can be adjusted by adjusting screws (38). To further improve the aforementioned type of wire stripper, it is suggested that the adjusting screw (38) be connected to an adjusting wheel (45) capable of aligning with a mark (46) for a basic position, the mark being fixed on one of the jaws (2, 3).

Claims

1. A wire stripper (1) having two jaws (2, 3), two outer clamping jaws (19, 20), two inner cutting jaws (22, 23), and two gripping parts (4, 5), wherein, The cutting jaws (22, 23) can move from a basic position to a terminal position during the closing of the gripping parts (4, 5), wherein the cutting jaws (22, 23) also have cutting elements (24, 25) with cutting blades (32, 33), wherein the cutting blades (32, 33) are positioned relative to each other at a defined distance (a) in a defined position, wherein the cutting jaws (22, 23) move toward each other in this defined position, wherein the distance (a) in the position considered as the basic position can be adjusted by an adjusting screw (38), wherein the adjusting screw (38) can be connected to an adjusting wheel (45), the adjusting wheel can be aligned with a mark (46) for the basic position, the mark being fixed on one of the jaws (2, 3).

2. The wire stripper according to claim 1, characterized in that, The position of the adjusting wheel (45) relative to the adjusting screw (38) can remain unchanged.

3. The wire stripper according to claim 2, characterized in that, The fixing is achieved by a fixing bolt (53) that passes through the adjusting wheel (45) and is accommodated in the thread of the adjusting screw (38).

4. The wire stripper according to claim 3, characterized in that, The fixing can be achieved by engaging the adjusting wheel (45) in a shaped manner with the adjusting screw (38).

5. The wire stripper according to any one of the preceding claims, characterized in that, The adjusting wheel (45) works in conjunction with the locking device (60) fixed on the jaws (2, 3).

6. The wire stripper according to claim 5, characterized in that, The locking device (60) has a protruding, elastic locking protrusion (62) that is embedded in the locking recess (64, 64') of the adjusting wheel (45).
