Abstract

The utility model discloses a double-high-neck spanner, which comprises a spanner body (3), a first high neck (2), a second high neck (4), a first spanner jaw (1) and a second spanner jaw (5), wherein one end of the first high neck (2) and one end of the second high neck (4) are respectively connected with both ends of the spanner body (3), the other end of the first high neck (2) is connected with the first spanner jaw (1), the other end of the second high neck (4) is connected with the second spanner jaw (5), the first high neck (2) and the second high neck (4) are respectively positioned at both sides of the spanner body (3), the cross section of the inner hole of the first spanner jaw (1) is in a pentagonal shape, and the cross section of the inner hole of the second spanner jaw (5) is in a hexagonal shape. After the structure is adopted, the special high-neck spanner with the pentagonal inner hole can be used in some occasions with narrow space by aiming at pentagonal head screw bolts or screw nuts, simultaneously, the double-high-neck spanner can also be applicable to hexagonal head screw bolts or screw nuts, the application range is wider, and the function is multiple.

Description

Two hub spanners

Technical field

The utility model relates to hardware ﹠ tools class field, specifically is a kind of pair of hub spanner.

Background technology

In the hardware ﹠ tools field, double (end) wrench has the branch of straight neck, short neck, curved neck and hub.Two hub spanners of prior art generally comprise two sections opposite hubs of wrench body, direction and two and pull mouth, and every section hub end respectively connects and pulls mouth, and the other end connects wrench body.Because the bolt on the market or the head of nut are commonly hexagon, therefore, the endoporus that mouth is pulled at two of two hub spanners also is corresponding hexagon.But because the bolt of turret head or the contact-making surface of nut and spanner are six, wherein the contact area of each face is little, and therefore, in the use of spanner, the user exerts oneself a little, just skidding might occur.At this phenomenon, a kind of bolt or nut of five angle heads appearred at present on the market, and still, this bolt or nut do not have special-purpose hub spanner, use monkey wrench to operate usually, and this occasion less in some spaces is very inapplicable.In addition, this pair of hub spanner function singleness on the market, applicable situation is not extensive.

Summary of the invention

Technical problem to be solved in the utility model is, provide a kind of can with five corner bolts or the supporting use of nut, and can be applicable to multi-functional pair of hub spanner of the less occasion in space.

For solving the problems of the technologies described above, two hub spanners that the utility model provides, comprise that wrench body, first hub, second hub, first pull mouth and second and pull mouth, described first hub is connected with the two ends of wrench body respectively with an end of second hub, the other end of first hub and first is pulled mouth and is connected, the other end of second hub and second is pulled mouth and is connected, first hub and second hub lay respectively at the both sides of wrench body, described first shape of cross section of pulling the endoporus of mouth is a pentagon, and second shape of cross section of pulling the endoporus of mouth is a hexagon.

After adopting above structure, the utility model compared with prior art has following advantage:

1) because on the basis of two hub spanners of prior art, the first endoporus cross section of pulling mouth all is designed to pentagon, therefore, at bolt with five angle heads or nut, narrow and small occasion just can be used the hub spanner of special-purpose pentagon endoporus in some spaces;

2) simultaneously, one is that first of pentagon endoporus is pulled mouth, and the other end is that second of hexagonal internal bore is pulled mouth, makes the utility model both can be suitable for the bolt or the nut of five angle heads, can also be suitable for the bolt or the nut of turret head, the scope of application is more extensive, function is more.

Description of drawings

Fig. 1 is the structural representation of the two hub spanners of the utility model;

Fig. 2 is the structural representation of A-A direction among Fig. 1.

Wherein, 1, first pull mouth; 2, first hub; 3, wrench body; 4, second hub; 5, second pull mouth.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

By the structural representation of the two hub spanners of the utility model illustrated in figures 1 and 2 as can be known, it comprises wrench body 3, first hub 2, second hub 4, first pulls mouth 1 and second pulls mouth 5, described first hub 2 is connected with the two ends of wrench body 3 respectively with an end of second hub 4, the other end of first hub 2 and first is pulled mouth 1 and is connected, the other end of second hub 4 and second is pulled mouth 5 and is connected, first hub 2 and second hub 4 lay respectively at the both sides of wrench body 3, described first shape of cross section of pulling the endoporus of mouth 1 is a pentagon, and second shape of cross section of pulling the endoporus of mouth 5 is a hexagon.

The two hub spanners of the utility model only need to select corresponding first to pull mouth 1 according to the dimensions of five angle head bolts or nut in use, and the first pentagon inner hole sleeve of pulling mouth 1 on the bolt or nut head of five angle heads, is got final product along the circumferencial direction rotation of pulling mouth.In addition, this pair hub spanner utilizes second to pull bolt or the nut that mouth 5 is applicable to turret head commonly used, and usage is same as above.

Claims

1. two hub spanner, comprise wrench body (3), first hub (2), second hub (4), first pulls mouth (1) and second pulls mouth (5), described first hub (2) is connected with the two ends of wrench body (3) respectively with an end of second hub (4), the other end of first hub (2) and first is pulled mouth (1) and is connected, the other end of second hub (4) and second is pulled mouth (5) and is connected, first hub (2) and second hub (4) lay respectively at the both sides of wrench body (3), it is characterized in that: described first shape of cross section of pulling the endoporus of mouth (1) is a pentagon, and second shape of cross section of pulling the endoporus of mouth (5) is a hexagon.
