Abstract
The utility model relates to a kind of special tool wrench, particularly a multi-specification mouth wrench which can loosen and tighten different kinds of hexagonal nuts with a wrench and can replace three or four wrenches; in the wrench, the left and right mouths are connected to be an integrated body through an arm rod; the left and right mouths are all formed by hexagonal nuts of at least two specifications to overlap along a certain arc from small to large; the utility model is simple in structure, convenient in use, and can save labor and time; one wrench can be used to replace a plurality of wrenches.
Description
Technical field
The utility model relates to a kind of specific purpose tool spanner, especially relate to a kind of use one spanner can the various hex nuts of degree of tightness, can replace three to four many specifications of spanner Socket screw wrenches.
Background technology
At present, the Socket screw wrench that people generally use generally all is made up of the nut running-on of two single gauge, and every degree of tightness that can only be used for spanner the nut of two kinds of specific standards is used; If people have also reduced operating efficiency going out, in the work such as flight-line maintenance, work high above the ground, carrying, use the spanner of plurality of specifications to bring inconvenience to the operator simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to use, use one spanner can the multiple hex nut of degree of tightness many specifications Socket screw wrench.
The utility model is realized in the following way:
A kind of many specifications Socket screw wrench is characterized in that: it be by about two running-ons be connected in one by an armed lever;
Two running-ons all are to comply with little of overlapping to form along a specific circular arc greatly by the hexagon of at least two kinds of specification nuts about described;
Two running-ons all are to comply with little of overlapping to form along a specific circular arc greatly by the hexagon of two kinds of specification nuts about described;
Two running-ons all are to comply with little of overlapping to form along a specific circular arc greatly by the hexagon of four kinds of specification nuts about described;
Two running-ons all are to comply with little of overlapping to form along a specific circular arc greatly by the hexagon of six kinds of specification nuts about described;
Two running-ons all are to comply with little of overlapping to form along a specific circular arc greatly by the hexagon of eight kinds of specification nuts about described.
The utility model has following effect:
1) simple in structure, easy to use, saving of work and time: the utility model is exactly that the cover mouth structure that has Socket screw wrench now is changed shape, two to four of ascending special nut hexagon specification are overlapped to form along a specific circular arc, during use, by the nut specification with running-on be inserted in, small dimension gently to draw spanner along circular arc be rotatable fulfiling assignment; It is existing many spanner that spanner replaces, carry, when mechanical installation, maintenance, work high above the ground, because factors such as number of tools minimizing, ancillary staff's minimizings, thereby saving of work and time.
2) nut is stressed evenly, difficult threads off: arc structure of the present utility model had both dwindled the size of running-on, simultaneously when spanner rotation fastening nut, the stressed contact point in the plane of arc structure and nut is at the middle part at hexagon edge, so stressed evenly and be difficult for making nut to thread off, the plane contact point of existing spanner and nut is in the bight of hexagonal, so very easily thread off.
3) cost of manufacture low, save steel: the utility model is because simple in structure, and casting is finished big in batches and since one spanner alternative existing 34 spanner, so can save a large amount of energy and steel.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of many specifications Socket screw wrench, as shown in Figure 1: it be by about two running-ons 1 be connected in one by an armed lever 2, about two running-ons 1 all be that hexagon by four kinds of specification nuts is according to little of overlapping to form along a specific circular arc greatly.
Can with about two running-on 1 usefulness by the hexagon of two kinds of specification nuts according to little to overlapping to form along a specific circular arc greatly.
Also can with about two running-on 1 usefulness by the hexagon of six kinds of specification nuts according to little to overlapping to form along a specific circular arc greatly.
Can with about two running-on 1 usefulness by the hexagon of eight kinds of specification nuts according to little to overlapping to form along a specific circular arc greatly.
The spanner that the utility model provides can be cast making, also can forge making.
