Abstract
The invention discloses an adjustable wrench which is characterized by consisting of a wrench main body, adjustment rods and an adjustment nut, wherein a small wrench head is arranged at one end of the wrench main body, and a large wrench head is arranged at the other end of the wrench main body; an axial through hole is formed in the middle of the wrench main body; the adjustment rods are arranged in the axial through hole; the left and right two adjustment rods are symmetrically arranged and are the same in diameter; the adjustment nut is arranged between the two adjustment rods; guide sleeves are arranged at the crosslinking ends of the adjustment rods and the large and small wrench heads. Compared with a conventional open-end wrench and a box spanner, the adjustable wrench is wide in use range and general in metric/inch; one wrench can be used for pulling all hexagonal nuts or bolts in a metric range by 6 to 19 and an inch range by 1/4' to 3/4'; meanwhile, the adjustable wrench is easy to operate and convenient to use; the working efficiency of an operator is improved.
Description
Technical field
The present invention relates to a kind of hand tools, particularly relate to a kind of adjustable spanner.
Background technology
The fork spanner, double offset ring spanner etc. of prior art can only be applicable to a kind of hex nut or bolt of size.If when having the nut of all size that varies in size or bolt to need to screw, the spanner of adapted plurality of specifications must could work, make operation become cumbersome, reduce the efficiency of operator on the one hand, also improve production cost comparatively speaking.
Summary of the invention
The present invention mainly solves the deficiency existing for prior art, thus it is adjustable to develop a kind of scope of application, adjustable spanner simple to operate.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of adjustable spanner, is characterized in that: be made up of wrench body, adjusting rod, adjusting nut; Described wrench body one end is provided with small wrench head, and the other end is provided with large driving end, and centre is axially extending bore; Be provided with adjusting rod in described axially extending bore, described adjusting nut matches with adjusting rod.
Technical scheme of the present invention can also be perfect further:
As preferably, described adjusting rod is left and right two, and diameter is identical, and namely the leading portion of adjusting rod is provided with screw thread with the adjusting nut section of matching.
As preferably, described left and right two adjusting rods are arranged symmetrically with, and adjusting nut is located at the centre of two adjusting rods.
As preferably, described wrench body is by core body and be socketed in the large driving end at core body two ends, small wrench head combines.
Described large and small driving end adopts steel alloy; Described core body and be greatly tight fit connection between driving end and small wrench head.
As preferably, the head of described small wrench head and large driving end is the hexagonal frame-shaped construction of inequilateral.
As preferably, described adjusting rod is round bar, and the back segment (namely going deep into the part of size driving end) of adjusting rod becomes two parallel planes by circular arc facing cut, and the thickness of two parallel surfaces is consistent with the thickness of large and small driving end.
As preferably, described adjusting rod and large and small driving end cross-linked side are provided with fairlead, the internal diameter tight fit of described fairlead external diameter and large and small driving end, and the endoporus of fairlead is consistent with the parallel plane of adjusting rod back segment and form slip cooperating relationship.
As preferably, the screw thread on described adjusting rod and adjusting nut is left hand thread.
As preferably, two end faces of described adjusting nut are provided with has certain flexible elastic tape, is slidably tight fit between described elastic tape and adjusting rod.
As preferably, described adjusting rod is positioned at the external diameter of first section of large and small spanner and the internal diameter of large and small driving end is slip cooperating relationship.
Beneficial effect of the present invention: compared with traditional fork spanner, double offset ring spanner, the scope of application is wide, and metric and English is general; Metric system 6-19,1/4 〞 made in Great Britain can be pulled with a spanner--all hex nuts within the scope of 3/4 〞 or bolt, and also simple to operate, easy to use, improve operative employee's task efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present invention;
Detailed description of the invention
Adjustable spanner as shown in Figure 1, is made up of wrench body 4, adjusting rod 3, adjusting nut 6; Described wrench body 4 is by core body 41 and be socketed in the large driving end 43 at core body two ends, small wrench head 42 combines.The head of small wrench head and large driving end is the hexagonal frame-shaped construction of inequilateral, and wherein large and small driving end adopts steel alloy, core body 41 and be tight fit connection between driving end 43 and small wrench head 42 greatly.There is axially extending bore the centre of wrench body 4, and described adjusting rod 3 is positioned at axially extending bore, and the adjusting nut 6 matched with adjusting rod 3 is located in the adjusting nut hole of core body 41.Described adjusting rod 3 is left hand thread with the screw thread of adjusting nut 6.Two end faces of described adjusting nut 6 are provided with has certain flexible elastic tape 5, described elastic tape and adjusting rod tight fit.Described adjusting rod 3 is left and right two, and diameter is identical, and length is identical, is arranged symmetrically with.Namely the leading portion of adjusting rod is provided with screw thread with the adjusting nut section of matching, and be thread segment 31, back segment, namely gos deep into the part of size driving end head, is milled with pair of parallel plane, is called parallel plane section 33, before parallel plane section 33, is extension diameter section 32.Described adjusting rod 3 and large and small driving end cross-linked side are provided with fairlead 2, and described fairlead external diameter is identical with the internal diameter of large and small driving end, and forms tight fit relation, and endoporus is identical with the plane-parallel shape of adjusting rod back segment and form slip cooperating relationship.Two end faces of described adjusting nut 6 are provided with has certain flexible elastic tape 5, and described elastic tape and adjusting rod form the tight fit relation that can slide.
