Abstract
The invention discloses a double-head ratchet spanner coupling method and structure of special D head chuck, which is characterized by the following: the size of two ends of ratchet is set to satisfy metric 10, 13 and 19 mm or British system 3/8, 1/2 and 3/4 as driving head of special D-head size, when the driving end of driving head bottom is 3/8, 1/2 and 3/4, the mating pattern adopts different sizes of D head for different sizes of driving head for two ends of the same spanner.
Description
Technical field:
The present invention relates to a kind of spanner structure, refer to a kind of double end ratchet spanner structure of special D-head blocking especially, also refer to a kind of double end ratchet spanner matching method of special D-head blocking simultaneously.
Background technology:
Size by present spanner two ends, regularly arrangedly get off according to certain all in regular turn, therefore be the then inconvenience of ten minutes of use on the special size, promptly as under the state that cooperates the use of D head, it is three groups of independent dimensions, as metric system 10,13 and 19mm or made in Great Britain 3/8,1/2 and 3/4 inch, the spanner of single head then need be provided with this metric system or three kinds of sizes made in Great Britain respectively, can blocking relative size D head, only behind the D head of this single spanner blocking relative size, during the action workpiece, only can be for it at single size, if the D head of different size promptly needs the spanner of different size to be used, SC service ceiling system is a lot of, and often can't be in good time find the spanner that can match or D head and can effectively use and use.
And the size of present double (end) wrench, be to arrange in regular turn respectively, there is no for it at special size as the aforementioned, therefore in the time of the D that will cooperate aforementioned three kinds of sizes, must take the spanner of three different sizes respectively, the inconvenience of ten minutes in the use, and behind the spanner that uses these three kinds of sizes, if when having same size to be used simultaneously, then can't be for it, so known spanner there is no the form of special designs for the D head of these three kinds of special sizes, therefore, be needleless at present to the D head of these three kinds of specific forms and the spanner that designs, with regard to the use of D head, inevitable inconvenience very is so there is necessity of improvement.
Summary of the invention:
Technical problem to be solved by this invention is: at the above-mentioned deficiency of prior art, provide a kind of, a kind of double end ratchet spanner matching method of special D-head blocking of the function that can reach the best fit stopper is provided simultaneously for making the most frequently used special size D head be cooperated the double end ratchet spanner structure of the special D-head blocking of relative double (end) wrench.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of double end ratchet spanner matching method of special D-head blocking, the driving head internal diameter size that this spanner bandle is provided with are respectively metric system 10,13 and 19mm or 3/8,1/2 and 3/4 inch made in Great Britain; Be characterized in that its matching method is: the above driving head inner radius of described spanner at least two groups becomes the design of each corresponding aforementioned different special size, and pairing in regular turn, three groups of different sizes is matched respectively be distributed on the spanner.
Described metric system 10,13 and 19mm or these three kinds of sizes of 3/8,1/2 and 3/4 inch made in Great Britain can be matched in twos respectively and are located on three spanners.Described metric system 10,13 and 19mm or these three kinds of sizes of 3/8,1/2 and 3/4 inch made in Great Britain can be located on the same spanner simultaneously.
A kind of double end ratchet spanner structure of special D-head blocking, its spanner is the ratchet spanner of a bullhead, its central authorities are a lever, and a driving head is extended in its lever both sides, the driving head that is characterized in described spanner two ends is designed at different special size D respectively, and the driving head size at its single spanner two ends can be 3/8 inch made in Great Britain, and metric system is 10mm, 1/2 inch made in Great Britain, and metric system is 13mm or is 3/4 inch made in Great Britain, and metric system is 19mm.
It is 10mm that the driving head size at described single spanner two ends can be metric system, and 3/8 inch made in Great Britain, another driving head is 13mm for metric system then, and 1/2 inch made in Great Britain.It is 13m that driving head size one end at described single spanner two ends can be metric system, and 1/2 inch made in Great Britain, and the size metric system of end is 19mm in addition, and 3/4 inch made in Great Britain.The driving head size at described single spanner two ends can be and is of a size of metric system is 19mm, and 3/4 inch made in Great Britain, and end is 10mm for metric system in addition, and 3/8 inch made in Great Britain.
Described spanner at least two group driving heads have aforementioned different special size and can be in twos a group.Described spanner at least two group driving heads have aforementioned different special size and can three groups of two have different size driving head spanner and are made into one group.Described driving head is unidirectional.Described driving head is capable of reversing.
A kind of double end ratchet spanner structure of special D-head blocking, its spanner is the ratchet spanner of a bull formula, its central authorities are a lever, and its lever extends at least one group driving head, are characterized in that the driving head of described spanner is designed at different special size D respectively, it is 10mm that its driving head size can be metric system, and 3/8 inch made in Great Britain, another driving head is 13mm for metric system then, and 1/2 inch made in Great Britain or for metric system be 19mm, and 3/4 inch made in Great Britain, the ratchet spanner of formation bull special size.
