Different screws can be screwed by changing the lower clamping holes.

The patent technology of Zhangxiaohong 'plug-in type multipurpose double offset ring spanner' (application number CN88206748.6 publication (announcement) number CN2032925U) relates to a novel double offset ring spanner. The wrench is formed by splicing a handle and two combined quincuncial bodies. The two ends of the handle are respectively provided with an invaginated quincuncial ring, and each combined quincuncial body is provided with four quincuncial rings with different specifications. The combined plum blossom body and the handle are convenient to disassemble and assemble and are positioned by the conical end fastening screw. The number of the Inclusion plum blossom wreaths with different specifications can reach ten.

The double offset ring spanner in the prior art has the following defects:

the special technology in the method has the advantages that 8 nuts with different specifications and sizes can be locked and unlocked, but the manufacturing is complex, the cost is high, and the using and the operation are complicated; secondly, the special technology can rotate different screws by changing the lower clamping hole, but the manufacturing is complex, the cost is high, and the using operation is complicated; and thirdly, the special technical wrench is formed by splicing a handle and two combined plum blossom bodies. The two ends of the handle are respectively provided with an invaginated quincuncial ring, each combined quincuncial body is provided with four quincuncial rings with different specifications, the manufacturing is complex, the cost is high, and the use and the operation are complex.

SUMMERY OF THE UTILITY MODEL

In view of this, for solving current box end wrench preparation complicated with high costs, use the complicated technical problem of operation, for this reason, the utility model provides a box end wrench, simple structure, it is with low costs, except that corresponding specification and dimension bolt, nut use, can also be used to slightly little specification and dimension bolt, nut use, reach save time, convenient, do not harm the purpose of bolt, nut.

In order to achieve the above object, the utility model provides a following technical scheme:

a double offset ring spanner comprises a double offset ring body with an opening, wherein a first handle and a second handle are connected to two ends of the opening, a double offset ring is arranged in the double offset ring body, and a double offset ring opening matched with the opening is formed in the double offset ring body.

Preferably, the first handle, the second handle and the plum blossom body are integrally formed.

Preferably, the material of box spanner is steel.

Compared with the prior art, the utility model, following beneficial effect has:

the utility model provides a box end wrench has solved the bolt that a box end wrench specification among the prior art can only be used for corresponding the specification, and the nut uses inconvenient technical problem.
