Description
Technical field
The utility model is related to electric wrench fields, and in particular to a kind of electric wrench sleeve.
Background technology
Current electric wrench, for the nut of different model, needs replacing the sleeve of corresponding model in operation process,
It is not only inconvenient in this way, have an effect on operating efficiency.
For this purpose, some utility models people devises knockdown sleeve, the sleeve combination of a variety of different size model numbers is existed
Together, the sleeve from-inner-to-outer of variant size model number is sequentially sleeved in together；Although such combined sleeve is convenient to use, can
To improve operating efficiency；But it has the following disadvantages：
Since inevitably there are certain gaps between sleeve each in combined sleeve, a certain be located at is being used in this way
The sleeve of inside come lock/dismantle nut during（It is illustrated for using and being located at innermost sleeve）：Sleeve
In each lateral surface：Handing-over side between two adjacent lateral surfaces is defined as the outer incline of sleeve, is being locked positioned at innermost sleeve
During tightly/dismounting nut, on the medial surface of sleeve that incline will be against adjacent outer outside the sleeve of innermost sleeve, come
Transmit the coupling mechanism force that electric wrench is acted on nut；Shape easily occurs positioned at the outer incline of the sleeve of innermost sleeve in this way
Become；And since the gap between each sleeve is inherently smaller, once shape occurs for incline outside the sleeve of innermost sleeve
Become, then can slide between innermost sleeve and the sleeve of adjacent outer, can thus influence to be located at most interior
The normal use of a sleeve on the outside of the sleeve of side even results in the problem of sleeve can not be used for locking nut.
Similarly, using any one positioned at the sleeve of inside come all there are the above problems during locking/dismantling nut.
Utility model content
The purpose of this utility model is to provide for a kind of electric wrench sleeve, can not only electric wrench be facilitated to tear open
The nut of different model is unloaded/locked, and incline outside the sleeve of the sleeve because being located inside in combined sleeve can be effectively improved
Deform upon, cause normally slide between sleeve, and influence combined sleeve can not normal use the problem of.
The technical solution of the utility model is：
A kind of electric wrench sleeve, including：Outer sleeve and the first inner sleeve, one end of the outer sleeve be equipped with for
First nut lock tieholen of nut cooperation, the cross section of the first nut lock tieholen is in regular polygon；The horizontal stroke of first inner sleeve
The outer profile in section is also in regular polygon, and the first inner sleeve is plugged in the first nut lock tieholen and can be along the first nut lock
Tieholen slides axially；In each medial surface of the first nut lock tieholen：Handing-over between two medial surfaces of arbitrary neighborhood
Inner wall deformation is equipped at side and reserves holding tank；In each lateral surface of first inner sleeve：Between two adjacent lateral surfaces
Handing-over side be defined as the outer incline of sleeve, and the outer incline of sleeve is located at corresponding inner wall deformation and reserves in holding tank.
This programme passes through in six medial surfaces of the first nut lock tieholen of outer sleeve：Two medial surfaces of arbitrary neighborhood
Between handing-over side at setting along the axially extending inner wall deformation of the first nut lock tieholen reserve holding tank, and make the first inner sleeve
