Description
Technical field
The invention belongs to a kind of Versatile manual tool, the swivel sleeve of especially a kind of metric system nut and spanner made in Great Britain and make
Use method.
Background technique
Existing fork spanner, double offset ring spanner, box spanner are all sold in set, and a set of more than ten, not only price is more expensive,
And weight weight, volume are big, not readily portable and keeping.The applicant has developed the replaceable spanner for pulling mouth thus, and one group is pulled
The function of set fork spanner, double offset ring spanner, box spanner that hand can play, reduces costs, easy to carry and keeping.But
It is pulled there are still limitation for this purpose, the applicant has applied for another several patents " convenient wrench " and " universal spanner head " using upper
Mouth is replaceable, but its structure still has limitation in use, is not able to satisfy wider requirement, is not able to satisfy a variety of
Dimension series requirement, meanwhile, the dimensional tolerance for pulling mouth is inconsistent, there is a problem of spanner matching difficulty, meanwhile, it is easy to cause and pulls
Hand slides sometimes in use, inconvenient for operation.
Summary of the invention
The object of the present invention is to provide the swivel sleeve of metric system nut and spanner made in Great Britain, the inside and outside of swivel sleeve is
Various shape polygon, sleeve body outside polygon size are greater than polygon size inside sleeve body.It is polygon outside swivel sleeve
The size h on two sides that shape is parallel to each other is the integral multiple of 1 millimeter (mm), the size model of the size h on two sides being parallel to each other
Enclosing is 2mm≤h≤230mm, and the size m on two sides that internal polygon is parallel to each other is the integral multiple of 1/32 inch (inch),
The size range of the size m on two sides being parallel to each other is 1/8inch≤h≤9inch.Metric system spanner pulls mouth and sleeve body
It is external with merging twisting sleeve body, the inside of sleeve body and English system nut (bolt or nut that screw, bolt, screw thread are tightly held,
Or other trepanning firmwares etc.) with above-mentioned nut made in Great Britain of twisting etc. is merged, sleeve body passes through external polygon and internal polygon
Cooperation nut made in Great Britain (bolt or nut or other trepanning firmwares that screw, bolt, screw thread are tightly held) is converted into metric system
Spanner twisting realizes the purpose for pulling a mouthful above-mentioned screw for twisting English system, bolt of metric system spanner.
The object of the present invention is achieved like this:
1, the swivel sleeve of a kind of metric system nut and spanner made in Great Britain, it includes sleeve body, it is characterized in that: the outside of sleeve body
A kind of polygon of specification is set, and the polygon of another specification is arranged in the inside of sleeve body, and sleeve body outside is more
The size of side shape is greater than the size of internal polygon, and pull mouth and the external polygon of sleeve body of spanner match and merge twisting sleeve
Body, the inside polygon and nut or screw fit and twisting nut or screw of sleeve body, sleeve body are pulled large scale spanner
Mouth is transitioned into the screw or nut of small size, and external positioning convex platform is arranged in the end of sleeve body or setting positioned internal is convex
Platform；The external polygon of sleeve body or internal multi-sided cross-sectional shape, the polygon being formed by connecting for regular polygon or curve or
Polygon or curve that straight line is formed by connecting and the polygon that straight line is formed by connecting, the external polygon of sleeve body or internal polygon
Shape corresponding sides are parallel or angled；
When external polygon with internal polygon is regular polygon and parallel corresponding sides, what external polygon was parallel to each other
The size h on two sides is the integral multiple of 1/32 inch (inch), and the size range of the size m on two sides being parallel to each other is 1/
8inch≤h≤9inch, the size m on two sides that internal polygon is parallel to each other are the integral multiple of 1 millimeter (mm), mutually flat
The size range of the size h on two capable sides is 2mm≤h≤230mm.
The size h on the mutual two parallel sides of the external polygon of above-mentioned sleeve body is the integral multiple of 1/32 inch (inch), h
Tolerance are as follows: lower deviation is negative, the upper deviation 0；The size m on two sides that internal polygon is parallel to each other is 1 millimeter (mm)
Integral multiple, the tolerance of m are as follows: lower deviation is positive number, and the upper deviation is also positive number.
The inside polygonal cross-section of above-mentioned sleeve body and external multi-sided cross-sectional shape are same or different.
Said external positioning convex platform or positioned internal boss are the polygon that round or regular polygon or curve are formed by connecting
Or polygon or discrete small boss that the polygon that is formed by connecting of straight line or curve and straight line are formed by connecting.
Groove or pit or through-hole are set on above-mentioned sleeve body.
Above-mentioned sleeve body is made of magnetic material or is embedded on sleeve body magnetic substance.
The periphery of above-mentioned sleeve body can be disconnection shape or defect shape.
It is above-mentioned that elasticity Fastener is embedded on sleeve body.
The application method of above-mentioned sleeve body: in use, the mouth of pulling of the external polygon of sleeve body and spanner is cooperated, it is external
What polygon penetrated spanner pulls mouth；It is more that the inside polygon and nut or screw fit of sleeve body, nut or screw penetrate inside
Side shape；Then nut is dismounted by the handle of twisting spanner.
The invention has the advantages that cooperation pulling large scale spanner of the sleeve body by external polygon and internal polygon
Mouth is transitioned into the nut (bolt or nut or other trepanning firmwares that screw, bolt, screw thread are tightly held) of small size, realizes big
The purpose of the above-mentioned screw for pulling mouthful twisting small size of size spanner, bolt.The range of common spanner institute twisting nut is expanded,
Various shape polygon is used inside and out swivel sleeve, can preferably protect nut, nut is avoided to be damaged by twisting.Set
The internal or external setting positioning convex platform of cylinder, not only plays the role of dowelled spanner and nut, prevent twisting tool be pierced by or
It slips, and increases sleeve body intensity.Elastic Fastener on sleeve body makes swivel sleeve be not easy to slide in use or move
It is dynamic, it is easy to operate.
The swivel sleeve and application method of metric system nut of the invention and spanner made in Great Britain, are not only applicable to that " large scale is pulled
The nut of hand pulled mouth and be transitioned into small size ", he is equally applicable to coaxial and size there are the transition between the part in gap,
The internal diameter of large-scale part is transitioned into the outer diameter of small size part.
