Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figure 1 and Figure 2, electrician's pliers of the present utility model, comprises hinged upper pincers 8 and lower pincers 9, at least one group of wire stripping edge of a knife 5, at least one group of disconnected sword 6, broken line structure and astragal structure; Described disconnected sword 6 is arranged on the straight sword on the working face of pincers 8 and lower pincers 9, and the described wire stripping edge of a knife 5 is arranged on the cutting edge caving on the working face of pincers 8 and lower pincers 9; Described broken line structure comprises broken line binding clip 2 and the broken line groove 1 with broken line binding clip 2 adaptations, described broken line binding clip 2 is parts of protruding on upper pincers 8 working faces, protrusion direction is identical with the direction of putting the first edge on a knife or a pair of scissors of the disconnected sword 6 of upper pincers 8, and described broken line groove 1 is the part caving on the working face of lower pincers 9; Astragal structure is arranged on the astragal circular hole 4 on pincers 8 back sides or lower pincers 9 back sides; The working face of pincers point 3 parts of described upper pincers 8 and lower pincers 9 is provided with tooth mouth.

Two states is opened, closed up to upper pincers 8 after hinged and lower pincers 9, and while closing state, the contact-making surface of upper pincers 8 and lower pincers 9 is working face, and the back side of upper pincers 8 and lower pincers 9 is relative with described working face.The wire stripping edge of a knife 5 is the structures that divest electric wire insulation layer, and when upper pincers 8 and lower pincers 9 close up, the wire stripping edge of a knife 5 can form a closed Zhou Ren, and all swords can not injure under the prerequisite of core, wipe out the insulating barrier of electric wire.Disconnected sword 6 is to be straight sword, electric wire entirety can be cut off.Broken line binding clip 2 and broken line groove 1 are for by the structure of electric wire knuckle, and the broken line binding clip 2 of protrusion is corresponding with the broken line groove 1 of depression, and electric wire is put into the rear clamping electrician's pliers of broken line groove 1, and electric wire can be converted into certain angle with broken line groove 1 shape.Astragal circular hole 4 is the structures that help wire forming, and wire is inserted after circular hole, and rotation electrician's pliers, can become electric coil required circle.The flank of tooth of pincers point 3 is that the lines of tooth can be equidirectional, also can interlock for the structure that better pincers are got workpiece.

The utility model is arranged on the functional structure of multiple electrician's pliers on same electrician's pliers, makes the utlity model has several functions, and in the time of electric work, only need to carry a kind of electrician's pliers can corresponding working procedures.

Electrician often needs live line working, for better protection electrician's personal safety, in the present embodiment: above clamp 8 and lower pincers 9 on be equipped with clamp handle 7, described clamp handle 7 is provided with insulating protective layer.When Electrician Operation, clamp handle 7 is parts that electrician directly contacts with circuit, and insulating barrier is set at this position can be effectively by human body and circuit isolation.

When electrician's pliers will be given electric wire knuckle, the number of degrees of knuckle are relevant with the shape of working surface of broken line groove 1 and broken line binding clip 2.The working face of broken line binding clip 2 is cambered surface or at least two planes or plane and cambered surface combination, the working face of broken line groove 1 with the working face adaptation of broken line binding clip 2.When broken line binding clip 2 working face position of broken line are level and smooth not at an angle, in broken line process, may injure electric wire with the broken line binding clip 2 of certain angle.Fig. 3 is to be broken line groove 1 detail drawing, and Fig. 4 is that Fig. 3 breaks the A at place to the schematic diagram of plane 11 and cambered surface 12, cambered surface angle [alpha]=90 degree in figure.The present embodiment is by preferred: the working face of described broken line groove 1 is made up of cambered surface 12 and a plane 11 of one 90 degree, and described cambered surface 12 extends to plane 11 from the edge 14 of caliper upper surface 13, and this plane 11 extends to caliper lower surface 15 always.Caliper upper surface 13 is electrician's pliers one sides upward while keeping flat, and lower surface with it correspondence is electrician's pliers one side down while keeping flat.Electric wire is put into broken line groove 1 and clamp electrician's pliers, electric wire is subject to broken line binding clip 2 and 1 extruding of broken line groove to form the knuckle of one 90 degree.Plane 11 is tangent with cambered surface 12, and it is smoother that both form the 2 working face transition of broken line binding clip, can reduce the damage to electric wire in extruding electric wire process.

While divesting insulating barrier, when the wire stripping edge of a knife 5 excises electric wire insulation layer, should avoid switching to wire core, so for the specification difference of the electric wire wire stripping edge of a knife 5 of different size as far as possible.When electrician's pliers closes up, all swords that the wire stripping edge of a knife 5 forms can be polygon, ellipse and circular.The present embodiment is through preferred: described upper pincers 8 are provided with lower pincers 9 five groups of wire stripping edges of a knife 5 that are arranged symmetrically with, and the Zhou Ren that the described stripping wire stripping edge of a knife 5 forms is for circular, and described all sword diameters are respectively: 0.8 millimeter, 1.0 millimeters, 1.4 millimeters, 2.0 millimeters, 2.7 millimeters.Above-mentioned all sword diameters refer to the diameter at all sword cutting edges place.

When electrician encircles money, often corresponding is plain conductor, and described astragal circular hole 4 need to block core, and Circularhole diameter should be greater than wire core diameter, but difference should be not excessive.In the present embodiment: the quantity of described astragal circular hole 4 is two, its diameter is respectively 1.0 millimeters and 2.0 millimeters, and described two kinds of circular holes can be contained the core using in family expenses electric wire field substantially.
