Description

Sheath cutting pliers

One. technical field: the utility model relates to a kind of apparatus for peeling off of electric wire, particularly relates to a kind of sheath cutting pliers.

Two. background technology: along with the development of economy and technology, various electric power of China and electric equipment more and more need expansion, move and change, so just need a large amount of electric wire and cables that disconnects, particularly the digging electric equipment in mine or colliery moves frequently, power line disconnects more, labour intensity is big, and it is quick-fried that wiring does not with great difficulty cause electrical equipment to lose, thereby cause gas explosion, in order to raise the efficiency, people usually adopt stripping tool, and wire stripping pliers commonly used all are edges of a knife that different bores are set at its pincers end, to adapt to the not needs in collinear footpath, as: Chinese patent (notification number CN862062484U, the patent No. is 86206284) a kind of " wire stripping pliers " disclosed, it is on the basic structure basis of common pliers binding clip and pincers handle to be changed, wherein binding clip is made factory's shape, the binding clip port is made the corresponding some sharp keen edges of a knife that differ in size of thickness with institute's wire stripping, between the pincers handle, be equipped with and make the automatic open spring of jaw, only at the closed wire stripping of jaw firmly, it is automatic that jaw opens during use.But the binding clip of the wire stripping pliers of this class formation and caliper are integral structure, after the edge of a knife wearing and tearing, it is big that the aperture becomes, and well wire stripping can only be dragged firmly, so not only influence operating efficiency, and increase labor intensity of operating personnel, after the edge of a knife heavy wear, can not change the edge of a knife, have only whole caliper is scrapped, cause waste, and increase the enterprise operation cost, it can only be applicable to the thinner cable in line footpath in addition, is unfavorable for promotion and implementation.

Three. the utility model content:

The purpose of this utility model: overcome the defective of prior art, provide a kind of simple in structure, cost is lower, can change the sheath cutting pliers of cutter head and easy accessibility.

The technical solution of the utility model: a kind of sheath cutting pliers, contain upper clamp, lower clamp and pin, wherein, the front portion intersection of upper clamp and lower clamp contacts and is hinged by pin, upper and lower caliper is realized folding by pin, wherein the front end of upper and lower caliper flexibly connects with upper and lower cutter head respectively, and be respectively equipped with an isometrical semicircle on the corresponding medial surface of upper and lower cutter head and shear the edge of a knife, when upper and lower cutter head contacts, form the circular edge of a knife of shearing, this circle is sheared the diameter of the edge of a knife and the diameter of electric wire is complementary.

The medial surface of described upper and lower caliper rearward end is respectively equipped with an alignment pin, is set with stage clip on two alignment pins, makes upper and lower cutter head be in normally open.

The medial surface of described upper and lower caliper leading section is respectively equipped with an alignment pin, is set with stage clip on two alignment pins, makes upper and lower cutter head be in normally open.

The rearward end of described upper and lower cutter head flexibly connects with the leading section of upper and lower caliper respectively by screw thread, and perhaps, the rearward end of described upper and lower cutter head flexibly connects with the leading section of upper and lower caliper respectively by buckle; Described upper and lower cutter head is the series of bits that is provided with the different-diameter semicircle edge of a knife.

The rear portion of described upper and lower caliper is respectively installed with insulating case, is convenient to live line working.

The beneficial effects of the utility model:

1. the utility model high efficiency and laborsaving, two semicircle edges of a knife of shearing of its front end are clamped electric wire, and the electric wire skin is cut off, operating personnel only need one to draw backward, the electric wire skin can be peeled off, facts have proved, the utility model saves for 25% time than common wire stripping pliers, so its efficient height, in addition, electric wire and upper and lower caliper are in the same way, operating personnel exert oneself backward, meet the firmly custom of arm, and it has changed about the common arm that adopts exerts oneself, so, more convenient and laborsaving.

The utility model easy to use, save material, its cutter head is movable the connection with caliper, the shearing edge of a knife on the cutter head can make the specification that varies in size, and adapts to the not needs in collinear footpath by changing cutter head, in addition, for through being usually used in same kind of specification electric wire, it has incomparable advantage: do not have other slot arrangement, alleviated the weight of whole caliper, be convenient to operation, and therefore the reduction labor intensity of operating personnel is used very convenient.After edge of a knife wearing and tearing, only need to change cutter head and get final product, do not need caliper is scrapped, so save material, reduce the operating cost of enterprise.

3. the utility model making simple in structure, easy, caliper and pin are common common components, buy easily or make, cutter head structure is simple in addition, and its side only need process semicircle sharp keen blade and get final product, and screw thread or buckle are processed in its rear end, be conventional processing technology, so, make easily, and cost is lower.

4. the utility model is simple to operate, and the medial surface of upper and lower caliper rearward end or leading section is respectively equipped with an alignment pin, is set with stage clip on two alignment pins, makes upper and lower cutter head be in normally open, and therefore, only need hold with a firm grip during use gets final product, easily operation.

5. the utility model scope of application is wide, particularly is applicable to the digging electric equipment in mine or colliery, and the cable diameter of the stripping of cutting is thicker, is easy to promote, and has good social and economic benefit.
