Description

Double (end) wrench

Technical field

The utility model relates to hardware & tools class field, specifically is a kind of double (end) wrench.

Background technology

In the hardware & tools field, double (end) wrench has the branch of straight neck, short neck, curved neck and hub.The straight neck double (end) wrench of prior art generally comprises wrench body and two and pulls mouth, and the two ends of wrench body connect one respectively and pull mouth.Because the bolt on the market or the head of nut are commonly hexagon, therefore, the endoporus that mouth is pulled at two of this double (end) wrench commonly used is the quincunx of corresponding twelve edge.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.To 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 spanner, use monkey wrench to operate usually, and this occasion less in some spaces is very inapplicable.In addition, double (end) wrench function singleness on the market, applicable situation is not extensive.

Summary of the invention

The utility model technical problem to be solved is, provide a kind of can with five corner bolts or the supporting use of nut, and can be applicable to the multi-functional double (end) wrench of the less occasion in space.

For solving the problems of the technologies described above; The double (end) wrench that the utility model provides; Comprise that wrench body, first pulls mouth and second and pull mouth; Described first pulls mouth and second pulls the two ends that mouth is connected to wrench body, described first pull the endoporus of mouth shape of cross section be pentagon, second pull the endoporus of mouth shape of cross section be quincunx.

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

1) because on the basis of the double (end) wrench of prior art, with first pull mouth the endoporus cross section all be designed to pentagon, therefore, to bolt with five angle heads or nut, narrow and small occasion just can be used the spanner of the pentagon endoporus of special use in some spaces;

2) simultaneously; One is that first of pentagon endoporus is pulled mouth, and the other end is that second of quincunx endoporus 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 or four angle heads, the scope of application is more extensive, function is more.

As improvement, described second pull the endoporus of mouth shape of cross section be the quincunx of twelve edge.Adopt the quincunx endoporus cross section of twelve edge, can make the contact area of bolt or nut and spanner of turret head or four angle heads bigger, also guarantee the popularity of use simultaneously.
