Description

Universal rotary tool for electrician

The invention belongs to the manual utensil of a kind of electrician, particularly a kind ofly can integrate wire stripper, point is chewed electrician's general-purpose device of the function of pincers, round nose pliers, voltage test pencil, screwdriver, universal screw wrench, seven kinds of electrician's instruments of electrician's knife.

The common hand-operated tools of known electrician has point to chew pincers, voltage test pencil, wire stripper, round nose pliers, screwdriver, spanner and electrician's knife.These seven kinds of instruments often are the carry-on instrument of electric work, and its shortcoming is, any all can not become finishes electrician's distribution and jointer separately, and overall manufacturing cost height, inefficiency, carry inconvenience, scatteredly lose easily.

Though China utility model patent specification notification number 2042778U discloses a kind of electrician multi-purpose pincers that have curved line, bare wire and pinch three kinds of functions of line, though this pincers increase compared with its operating efficiency of traditional electricians' plier, can not finish the elemental operation of electrician's electrical verification, wiring separately with it.And its moulding also is traditional " scissors-type ", so cost can be not low yet.

Task of the present invention provides a kind of electrician's ten thousand electrical equipment, and it can replace wire stripper, point to chew the function of pincers, round nose pliers, electrician's knife, voltage test pencil, screwdriver, seven kinds of electrician's instruments of universal screw wrench.

Task of the present invention is finished as follows: the conical rotating knife that puts an opening outside half a taper cutter of fixing, dead knife down is respectively the sharp knife sword by the top, the bare wire groove, section and stiff end, difference according to conductor cross-section, the bare wire groove is made into plurality of specifications, stiff end is fixed on the insulation handgrip, for making the insulating barrier of peelling off line end and simmering these two operations of circle and carry out simultaneously, voltage test pencil adopts half cone-shaped metallic test contact, and with the synthetic taper shape of half cone-shaped dead knife, leave between the two the space allow by the stripping lead pass, test contact and dead knife pass through thread connection, can will or be cut off object by bare conductor by the rotary test contact clamps in advance, be enclosed within the rotating knife that the half cone-shaped dead knife is a cone shaped opening outward, rotating knife down is respectively a draw-in groove by the top, interior bare wire groove, the inscribe section, interior contact-making surface, the arm of force and screw, wrench is equipped with in arm of force the inside, and wrench can be flexible along the arm of force, so that regulate the length of the arm of force.Peeling the cable outer layer insulating barrier when making end off can partly cooperate with the draw-in groove of rotating knife with the sharp knife sword of dead knife and finish, peelling off the insulating barrier of line end and simmering circle is common realization of test contact of mixing voltage test pencil by the bare wire groove of dead knife and rotating knife, and cutting off object is to finish by the section of dead knife and rotating knife.

Below with reference to accompanying drawing invention is described in further detail.

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the present invention.

Fig. 2 is the left view (taking off cutter cap＜20〉back) of Fig. 1

Fig. 3 is the cutaway view of Fig. 1 general-purpose device along III-III line.

Fig. 4 is the cutaway view of Fig. 1 general-purpose device along IV-IV line.

With reference to Fig. 1,2,3 and 4, half cone-shaped dead knife＜1〉with high rigidity and excellent abrasive resistance is moulded casting in insulation handgrip＜4 〉, here, dead knife＜1〉is made into and includes sharp knife sword＜15 〉, bare wire groove＜16 〉, guide groove＜17〉and stiff end.The profile of insulation handgrip＜4〉is made the plum blossom shape by the insulating materials of apparatus good mechanical strength and high rigidity, to reach when using not only safety but also labour-saving purpose.Open circles taper rotating knife＜2〉is enclosed on the dead knife＜1 〉, rotates along guide groove＜17〉by positioning screw＜19 〉.Rotating knife＜2〉is made into and contains draw-in groove, bare wire groove, section and screw etc. and can cooperate with dead knife＜1〉each several part, the arm of force＜13〉connects with rotating knife＜2〉by hinge pin＜14 〉, when carrying out bare wire and cutting off object, the perpendicular arm of force＜13〉of rotation and rotating knife＜2〉gets final product, and the arm of force when not working＜13〉can close and rotating knife＜2〉sticks together.The universal screw wrench of being made up of insulated handle＜10 〉, worm screw＜21 〉, screw＜18〉and movable binding clip＜22〉is connected with the arm of force＜13〉by screw＜11 〉, insulated handle has chute in＜10 〉, cooperate the length that just can regulate the arm of force＜13〉with screw＜11 〉, thereby able to increase force moment reduces operation firmly, also can universal screw wrench be taken off as general wrench from the arm of force＜13 〉, can be collected in the arm of force＜13〉lining at ordinary times by unscrewing screw＜11 〉.By the test contact with good electrical conductivity and mechanical strength＜3 〉, insulation crust＜5 〉, hand electric shock plate＜6 〉, cylindrical spring＜7 〉, neon tube＜8 〉, the voltage test pencil that current-limiting resistance＜9〉is formed, connect by the stiff end of screw thread with dead knife＜1 〉, test contact＜3〉is made into half cone-shaped, the top is made into the screwdriver shape can use by the double as screwdriver voltage test pencil, the test contact of half cone-shaped＜3〉just forms a taper shape with the dead knife＜1〉of half cone-shaped like this, keep certain space between the two, match with the draw-in groove of rotating knife＜2〉in this space, allow and passed, rotate voltage test pencil and just can will place the object between test contact＜3〉and the dead knife＜1〉to clamp in advance by bare conductor or cut object.

When wire stripping is simmered the line operation, to treat that earlier naked insulated conductor places suitable bare wire groove＜16〉lining, rotating voltage test pencil clamps lead in advance, two hands are held insulation handgrip＜4〉respectively and are rotated the arm of force＜13〉rotating knife＜2〉is rotated a circle around dead knife＜1〉then, this moment, conductor wire end was not only peeled off insulating barrier, and the line end after naked simmered into circle, and lead does not require when simmering into the wiring circle, voltage test pencil can be taken off, can finish bare wire as stated above.When cutting off the object operation, object to be cut is placed between the section of dead knife＜1〉and rotating knife＜2 〉, voltage test pencil can be used to object is clamped in advance, also can take off need not, two hands are held insulation handgrip＜4〉respectively and are rotated the arm of force rotating knife＜2〉is cut off object around dead knife＜1〉rotation then.In addition, the set universal screw wrench of the present invention also can be taken off as general wrench, voltage test pencil can replace common electroprobe to carry out electrical verification and the double as screwdriver is used, the sharp knife sword＜15〉of dead knife＜1〉can replace electrician's knife to use, as when making end, sharp knife sword＜15〉cooperates with the draw-in groove of rotating knife＜2〉peels off the cable outer layer insulating cement than higher, safer with its efficient of electrician's knife.Safe to carry for guaranteeing, the present invention also is provided with cap＜20〉and is enclosed on the top of rotating knife＜2 〉.

Compare with traditional electrician's instrument, the present invention has compact conformation, and volume is little, complete function, and production cost is low, saves material, and high efficiency is easy to carry, uses the advantages such as safety.
