Description
Technical field
The utility model relates to electrician's knife technical field, is specifically related to a kind of multiduty elbow electrician's knife.
Background technology
When exploiting insulated wire, insulated cable crust, need to use electrician's knife.Electrician's knife of the prior art only has single cutting function usually, for longer or softer wire, need another hand of hand-held electrician's knife to look for cutting place near wire to hold wire, cut ceaselessly movable conducting wire, not only inefficiency also easily causes accidental injury simultaneously.And common electrician's knife is when exploiting round insulation crust, wastes time and energy, is not easy exploitation and may damages operator.
In sum, how the problem of a kind of electrician's knife of the prior art not easily cutting wire round insulation crust and flexible conductor is provided, has become those skilled in the art to need the technical problem of solution badly.
Utility model content
The purpose of this utility model is to provide a kind of elbow electrician's knife, solves the problem of electrician's knife of the prior art in prior art not easily cutting wire round insulation crust and flexible conductor.
Solution of the present utility model is achieved in that and comprises blade and handle of a knife, handle of a knife is the hollow cavity being provided with opening, described blade comprises the first blade and the second blade, described first blade and described handle of a knife removably connect, and described first blade can fold around the tie point with handle of a knife described in it accepting groove being contained in described handle of a knife to blade direction; Described first blade front end is provided with the concave shaped elbow to blade curving, and described elbow recess is provided with blade; Described first blade is provided with the groove of accommodating described second blade, described second blade and described first blade hinged and can rotate around described pin joint.When use operates, first blade is launched in handle of a knife, hold handle of a knife, according to insulated wire, insulated cable insulation sheath thickness, the point of a knife of the first blade and concave shaped elbow is used to hook in insulation sheath, hoop turns around, more longitudinal hook in insulation sheath is outwards marked, just can easily by insulation sheath exploitation process.Owing to being provided with two blades varied in size, can cut the wire sheath of different-diameter size, applied widely, easy to use, cost of manufacture is low.
The utility model is on the basis of technique scheme, and under described second blade housed state, the blade of described second blade and the blade of described first blade are positioned at heteropleural.
The utility model is on the basis of technique scheme, and described handle of a knife is provided with the protection button preventing the first blade from extracting.
The utility model is on the basis of technique scheme, and a side surface of described handle of a knife is provided with file face.
The utility model is on the basis of technique scheme, and a side surface of described first blade is provided with scale.
The utility model is on the basis of technique scheme, and described first blade and the second blade are when deployed condition, and angle angle is therebetween 5-60 degree.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.
Fig. 1 is the utility model structural representation; Fig. 2 is the opposite side schematic diagram of the utility model structure.
In figure: 1 handle of a knife, 2 first blades, concavity elbow in 3,4 points of a knife, 5 blades, 6 play button, 7 accepting grooves, 8 second blades, 9 file faces, 10 scale markers.
Embodiment
Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection range of the present utility model.In addition, those skilled in the art, according to the description of presents, can carry out respective combination to the feature in embodiment in presents and in different embodiment.
Refer to Fig. 1, a kind of elbow electrician's knife of the utility model embodiment, comprise blade and handle of a knife, handle of a knife is the hollow cavity being provided with opening, described blade comprises the first blade and the second blade, described first blade and described handle of a knife removably connect, and described first blade can fold around the tie point with handle of a knife described in it accepting groove being contained in described handle of a knife to blade direction; Described first blade front end is provided with the concave shaped elbow to blade curving, and described elbow recess is provided with blade; Described first blade is provided with the groove of accommodating described second blade, described second blade and described first blade hinged and can rotate around described pin joint, the blade of described second blade and the blade of described first blade are positioned at heteropleural.When use operates, first blade 2 is launched in handle of a knife 1, hold handle of a knife 1, according to insulated wire, insulated cable insulation sheath thickness, the point of a knife 4 of the first blade and front end concave shaped elbow 3 is used to hook into the outer intracutaneous of wire insulation, hoop turns around, then hooks and longitudinally outwards mark in insulation sheath, just can be stripped out by insulation sheath easily.Electrician's knife in the present embodiment also can use as common electrical cutter, uses blade 5 and insulated wire, insulated cable insulation sheath angle at 45 °, outwards exploits insulating barrier.Owing to being provided with two blades varied in size, can cut the wire sheath of different-diameter size, applied widely, easy to use, cost of manufacture is low.
Continue see Fig. 1, described handle of a knife is also provided with the protection button preventing the first blade from extracting.The anti-protection button extracted is set, in use the first blade can be avoided to accidentally injure operator in operation.It is relative with the first knife-blade 5 that its blade rear opened by second blade 8, between angle be 5 to 60 degree, when using electrician's knife, by wire clamp between the first knife-blade 5 and the angle of the second blade 8 blade, the certain angle that tilted by first blade 2 is taken advantage of a situation cutting, the crust of long lead can be peeled, and grip cutting point without the need to another hand and mobile cutting.If wire is very soft, before cutting can first by wire around the second blade 8 one weeks, then take advantage of a situation and cut.This electrician's knife structure is simple, and easy to operate, cost of manufacture is low.And cutting long lead and flexible conductor are very simple and easy and conveniently, tangent line is laborsaving, quick.
