Abstract
The utility model discloses a metric and inch box wrench, which is composed of a handle and four jaws at both sides of the handle. Annular gears with identical teeth number are arranged on the inner walls of the four jaws, the inner diameter sizes of the four jaws are four different but adjacent sizes, wherein the inner diameter sizes of two jaws annular gear at one end of the handle are two adjacent sizes. The end surfaces of two jaws at one end of the handle are overlapped mutually, and the end surfaces of two jaws at the other end of the handle are also overlapped mutually. The handle is vertically connected with the jaws at both ends of the handle, and the joint is the centre position of the jaws. The utility model has the advantages that the structure is novel, a wrench is corresponding to four sizes, and therefore the using function can be greatly improved.
Description
Technical field:
The utility model relates to a kind of hardware ﹠ tools, a kind of metric and English double offset ring spanner of saying so more specifically.
Background technology:
Existing double end double offset ring spanner, can only be suitable for fastening, the dismounting of the hexagon-headed bolt (nut) of two kinds of specifications, because of hexagon-headed bolt (nut) specification has tens kinds, also with regard to tens of the corresponding double end double offset ring spanners of being furnished with all size, produce thus that specification is many, volume is big, price is high, select problems such as the double offset ring spanner of which kind of size dimension is difficult for determining for use, bring a lot of inconvenience to the user.Simultaneously, pulling of the handle of existing double end double offset ring spanner and two ends mouthful is connected for crooked, under some conditions can owing to hexagon-headed bolt (nut) fastening, the withdrawal space is narrow, thereby limit the use of double end double offset ring spanner.
Summary of the invention:
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of metric and English double offset ring spanner of easy to use, high efficiency.
The metric and English double offset ring spanner is pulled by handle and two ends four and mouthful is formed, four inwalls of pulling mouthful are equipped with the ring gear of the identical number of teeth, four ring gear internal diameters are of a size of each four unequal, adjacent size, wherein pull mouthful ring gear internal diameter and are of a size of two adjacent sizes for two of the same end of handle.Two at handle one end is pulled the end face of mouth and is folded mutually, and two of the handle other ends are pulled the end face of mouth and folded mutually.Handle is pulled mouthful vertical a connection with the handle two ends, and the junction is the centre position of pulling mouth.
Pull mouth for two of handle one end, the ring gear that bore is big, the length of its internal tooth surpasses 1/2nd of two ring gear total lengths.
Further scheme is, pulls mouth for two of handle one end, the ring gear that bore is big, and the length of its internal tooth is 3/5ths of two ring gear total lengths.
Advantage of the present utility model is, novel structure, and one can corresponding four sizes spanner, improve function of use greatly.Simultaneously, change the handle of spanner into vertical connection by being connected with the bending that pulls mouthful at two ends, in the out of use narrow space of common double offset ring spanner, metric and English double offset ring spanner connected vertically also can normally use, and has increased the scope of metric and English double offset ring spanner use.
Description of drawings:
Fig. 1 is the utility model schematic perspective view.
Fig. 2 is the utility model structure perspective view.
Among the figure 1 is handle, the 2,3,4, the 5th, and plum blossom is pulled mouth.
The specific embodiment:
The utility model will be further described below in conjunction with accompanying drawing.
Novel metric and English double offset ring spanner is pulled mouthfuls 2,3,4,5 by handle 1 and two ends four and is formed, pull the ring gear that mouthfuls 2,3,4,5 inwall is equipped with the identical number of teeth for four, four ring gear internal diameters are of a size of each four unequal, adjacent size, wherein pull mouthful 2,3 ring gear internal diameters and be of a size of two adjacent sizes for two of handle 1 one ends, pull mouthful 4,5 ring gear internal diameters for two of handle 1 other end and be of a size of two adjacent sizes.Two at handle one end is pulled the end face of mouth 2,3 and is folded mutually, and two of the handle other ends are pulled the end face of mouth 4,5 and folded mutually.Handle 1 and handle two ends pull mouthfuls 2,3 and pull mouthful 4,5 vertical connections, the junction is to pull mouthfuls 2,3 and the centre position of pulling mouth 4,5.
Pull mouth 2,3 for two of handle one end, the ring gear 2 that bore is big, the length of its internal tooth surpasses 1/2nd of two ring gear total lengths.
Further scheme is, pulls mouth 2,3 for two of handle one end, the ring gear 2 that bore is big, and the length of its internal tooth is 3/5ths of two ring gear total lengths.
