Description
Technical field
The utility model is related to electric wrench fields, and in particular to a kind of combined 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：
Due to inevitably there is certain gap between each sleeve in combined sleeve, it is located in this way using a certain
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 inner sleeve, exists positioned at innermost sleeve
During locking/dismounting nut, the outer incline of inner sleeve of innermost sleeve will be against the medial surface of the sleeve of adjacent outer
On, to transmit the coupling mechanism force that electric wrench acts on nut；The outer incline of inner sleeve for being located at innermost sleeve in this way is easy
It deforms upon；And since the gap between each sleeve is inherently smaller, once on the outside of the inner sleeve of innermost sleeve
Rib deforms upon, then can slide between innermost sleeve and the sleeve of adjacent outer, can thus influence
The normal use of a sleeve on the outside of most inner side sleeve even results in the problem of sleeve can not be used for locking nut.
Similarly, using any one lock/dismantle nut positioned at the sleeve of inside during all there is the above problem.
Utility model content
The purpose of this utility model is to provide for a kind of combined sleeve, can not only facilitate electric wrench dismounting/lock
The nut of tight different model, and incline outside the inner sleeve of the sleeve because being located inside in combined sleeve can be effectively improved and occurred
