Description

Multi-purpose wrench with double head

The utility model belongs to machinery and installs or repair outfit, the especially fork spanner of multipurpose double end.

Existing spanner both domestic and external is of a great variety, for example is suitable for adjustable wrench, hook spanner, double ended spanner and the modular sleeve spanner etc. of different size nut.Though various spanners use under different conditions, all there is a common problem in they, are exactly at the different size nut, need the spanner of different bore spanners.Multi-functional double offset ring spanner of Chinese patent CN85205504 and CN88213190.7 multipurpose wrench, to solve above-mentioned use deficiency, but its spanner needs several different model plum blossom spanners of cover in the larger caliber plum blossom spanner, in the gap can not tension between the cover plum blossom spanner, use and inconvenience, its complex structure, so this spanner has its certain limitation and influences it and applies.

The utility model has carried out the fork spanner of improvement, a kind of multipurpose double end of design at this problem, a plum blossom spanner front, reverse side pulls mouth or mouth and an open-end wrench front are pulled in the four sides, the reverse side different size pull mouth, make fork spanner replace two or three spanners, have a tool use more, simple in structure, volume is little, advantage such as in light weight, economic and practical.

The utility model is achieved by following manner, a kind of fork spanner of multipurpose double end, the bore of the spanner by two or the symmetrical specification different model in four sides are set on handle one end plum blossom spanner, at the handle other end open-end wrench front spanner internal orifice diameter is greater than or less than different size than reverse side spanner internal orifice diameter spanner bore is set, like this as long as the transposing different directions just can satisfy the instructions for use of four kinds or the six kinds different nuts of specification.

Said on a spanner spanner mouth minimum diameter, must guarantee that opposite face pulls the required gap of lead screw external diameter on mouthful interior intermediate nut, screw flight does not does not wear and tear during the loading and unloading nut.

The utility model is compared with prior art, have rational in infrastructure, a tool is used more, characteristics such as easy to use.

Fig. 1 is a schematic appearance of the present utility model;

Fig. 2 is plum blossom of the present utility model (opening) spanner generalized section;

Fig. 3 is four specification different size plum blossom spanner mouth generalized sections of the present utility model;

Among the figure: 1 plum blossom spanner, 2 fork spanners are (bar), 3 open-end wrenches, 4 positive plum blossom spanner internal orifices, 5 reverse side plum blossom spanner internal orifices, 6 front openings spanner internal orifices, 7 reverse side open-end wrench internal orifices.

Most preferred embodiment of the present utility model as Figure 1-3.A kind of fork spanner of multipurpose double end comprises plum blossom spanner (1) and open-end wrench (3) on handle (2) and the two ends thereof.The stiff hand of multiduty double end is according to four kinds or different nuts of six kinds of specifications or nuts, employing is provided with the mode of the spanner bore of the relative different size in positive and negative on same spanner, be just be provided with on plum blossom spanner (1) cross section (on) the plum blossom spanner internal orifice (4) of face and relative anti-(descending) face plum blossom spanner internal orifice (5), just (on) face pulls mouthful (4), minimum diameter must guarantee the 2 millimeters gaps of lead screw external diameter on relative plum blossom spanner internal orifice (5) intermediate nut.On the open-end wrench (3), just (on) face open-end wrench internal orifice (6) and relative anti-(descending) face open-end wrench internal orifice (7), minimum diameter must guarantee that other face pulls the lead screw external diameter 2-4 millimeter gap on mouthful intermediate nut.Fig. 3 pull between the mouth relatively because can be provided with four specification different size plum blossom spanner mouths at plum blossom spanner (1), minimum diameter must be greater than pulling tighten up a screw 2 millimeters of bar external diameters of a mouthful intermediate gap mother relatively, so according to nut size difference, can arbitrarily change positive and negative or use at the four sides, operation is very easy and be suitable for.

Claims (2)

1, a kind of fork spanner of multipurpose double end is made up of handle, plum blossom spanner, open-end wrench, it is characterized in that being provided with on the plum blossom spanner mouth of pulling of two kinds of different model bores.

2, the fork spanner of multipurpose double end according to claim 1 is characterized in that being provided with the mouth of pulling of two kinds of different model bores on open-end wrench.
