Abstract

Disclosed is a plum blossom spanner cushion which is a ring cushion made of metal sheet; the inner and outer ring edges all present the plum blossom shape; the inner and outer rings are all provided with 12 evenly divided angularities. The spanner cushion is composed of a group of mutually connected spanner cushions with big and small diameters; the width of each cushion ring rightly equals to the difference between adjacent big ring radius and smaller radius; the depth of the rings is equal, and all equals to the depth of the plum blossom spanner. 3 to 4 positioning blocks are arranged on the outer edge of each cushion ring so as to prevent the cushion ring from dropping off. The cushion is only needed to be nested into any common plum blossom spanner or the opening spanner when using the plum blossom spanner cushion; the plum blossom spanner cushion can be installed from big to small with layer by layer of embedded connection according to the using requirements, so as to remove the trouble of carrying more different size spanners, reduce the space occupied by the tool case, save the necessary total material consumption for the manufacturing factory, and reduce the production cost.

Description

The double offset ring spanner pad

Technical field

The utility model belongs to the annex of machine tool class, particularly spanner.

Background technology

Existing monkey wrench all is to drive the Flexible spanner mouth by the regulating wheel on the handle to move, and Flexible spanner mouth and the spacing of fixedly pulling mouth are changed, thus two corresponding limits of fishbolt or nut.Because bolt or nut mostly are hexagon or four limits, use existing monkey wrench, can only make stressed the rotating of two opposite side wherein, so often tightly do not cause coming off, skidding during work because of pressing from both sides.The back-up wrench that also has a kind of widely used double offset ring spanner or open type, though it can make hexagonal (hexagon)nut stressed accurately, stiff, use cumbersomely, must carry the plurality of specifications spanner.

Summary of the invention

The purpose of this utility model is to provide a kind of and is inserted in any one the spanner pad of common double offset ring spanner.

The utility model is achieved in that

A kind of double offset ring spanner pad, by the annular gasket that sheet metal is made, the inner and outer ring edge is quincunx, and inner and outer ring is provided with divides equally ten binary corner angle.It is made up of the spanner pad of the mutual socket of diameter of one group of annular, the width of each gasket ring just in time is radius poor of adjacent big or small ring, the consistency of thickness of ring all equates with the thickness of double offset ring spanner. each gasket ring outward flange is provided with 3-4 locator card, can prevent slippage.

When the utility model uses, only need that cushion cover is inserted in any one common double offset ring spanner or open-end wrench got final product. the requirement during by use, from big to small, layer overlaps, saved the worry of carrying the plurality of specifications spanner, reduced the space in tool box, simultaneously production plant, when producing, saved required overall consumptive material, saved production cost, market prospects are good, except producing metric system, can produce formula made in Great Britain.

The utility model spanner pad is long-pending little, in light weight, and the outward appearance exquisiteness is easy to carry, and is easy to use, is the flexible ideal tools of a cover.

Description of drawings

Figure I is the utility model structural representation,

Fig. 2 is the example structure schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

A kind of double offset ring spanner pad, as Fig. 1 annular gasket of being made by sheet metal shown in Figure 2, the inner and outer ring edge is quincunx, and inner and outer ring is provided with divides equally ten binary corner angle.It is made up of the spanner pad of the mutual socket of diameter of one group of annular, the width of each gasket ring just in time is radius poor of adjacent big or small ring, the consistency of thickness of ring, all equating with the thickness of double offset ring spanner. each gasket ring outward flange is provided with 3-4 locator card 1, can prevent slippage,, Fig. 1 and Fig. 2 are one group of adjacent spanner pad, the gasket ring of Fig. 1 just in time can be socketed among Fig. 2.

Claims

1, a kind of double offset ring spanner pad is characterized in that: by the annular gasket that sheet metal is made, the inner and outer ring edge is quincunx, and inner and outer ring is provided with divides equally ten binary corner angle.

2, double offset ring spanner pad as claimed in claim 1, it is characterized in that: the spanner pad by the mutual socket of diameter of one group of annular is formed, the width of each gasket ring just in time is radius poor of adjacent big or small ring, and the consistency of thickness of ring all equates with the thickness of double offset ring spanner.

3, double offset ring spanner pad as claimed in claim 1 is characterized in that: each gasket ring outward flange is provided with 3-4 locator card (1), can prevent slippage.
