Summary of the invention
The utility model mainly is to solve the existing in prior technology deficiency, thereby it is adjustable to develop a kind of scope of application, adjustable spanner simple to operate.
Above-mentioned technical problem of the present utility model 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 the small wrench head, and the other end is provided with big driving end, and the centre is an axially extending bore; Be provided with adjusting rod in the described axially extending bore, adjusting rod is left and right two, and the leading portion of adjusting rod promptly is provided with screw thread with the adjusting nut section of matching.
The technical solution of the utility model can also be further perfect:
As preferably, described left and right two adjusting rod symmetric arrangement, adjusting nut is located at the centre of two adjusting rods.
As preferably, described wrench body is combined by core body and the big driving end, the small wrench head that are socketed in the core body two ends.
Described large and small driving end adopts steel alloy; Be connected for tight fit between described core body and big driving end and the small wrench head.
As preferably, described small wrench head is the hexagonal shaped as frame structure of inequilateral with the head of big driving end.
As preferably, described adjusting rod is a round bar, and the back segment of adjusting rod (promptly going deep into the part of big or small driving end) becomes two parallel planes by the 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 the adjusting nut is a left hand thread.
As preferably, two end faces of described adjusting nut are provided with has certain flexible elastic tape, is tight fit slidably between described elastic tape and the 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.
The beneficial effects of the utility model: compare with traditional fork spanner, double offset ring spanner, the scope of application is wide, and metric and English is general; Can pull metric system 6-19,1/4 〞 made in Great Britain with a spanner--all hex nuts or bolt in the 3/4 〞 scope, and also simple to operate, easy to use, improved operator's operating efficiency.

The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
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 combined by core body 41 and the big driving end 43, the small wrench head 42 that are socketed in the core body two ends.The small wrench head is the hexagonal shaped as frame structure of inequilateral with the head of big driving end, and wherein large and small driving end adopts steel alloy, core body 41 be connected for tight fit between driving end 43 and the 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 that matches with adjusting rod 3 is located in the adjusting nut hole of core body 41.Described adjusting rod 3 is a left hand thread with the screw thread of adjusting nut.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, symmetric arrangement.The leading portion of adjusting rod promptly is provided with screw thread with the adjusting nut section of matching, and is thread segment 31, back segment, promptly go deep into the part of big or small driving end head, be milled with the pair of parallel plane, be called parallel plane section 33, in parallel plane section 33 fronts, for extension diameter section 32(sees Fig. 2,3,4).Described adjusting rod 3 is provided with fairlead 2 with large and small driving end cross-linked side, and described fairlead external diameter is identical with the internal diameter of large and small driving end, and forms the tight fit relation, the identical and formation slip cooperating relationship of plane-parallel shape of endoporus and adjusting rod back segment.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.
During use, because the screw thread on adjusting rod 3 and the adjusting nut 6 is a left hand thread, when turning clockwise adjusting nut 6, because the mating reaction between the parallel plane 33 of adjusting rod back segment and the fairlead 2, adjusting rod can not rotate with the rotation of adjusting nut, only produces to be moved to the left, make platelet at hand 42 working ranges dwindle, big driving end 43 working ranges enlarge, and can be adjusted to the aperture that hope reaches according to need of work; If be rotated counterclockwise adjusting nut 6, adjusting rod 3 moves right, and small wrench head 42 working ranges are enlarged, and big driving end 43 working ranges are dwindled, until be adjusted to meet the requirements till.
