The utility model provides a kind of Novel sleeve, includes sleeve body 1, and the top setting of sleeve body 1 is useful
In the bottom slot 2 cooperated with ratchet spanner, the bottom end of sleeve body 1 be provided with for external screw or nut cooperation
Bottom slot 3, bottom slot 3 are positive polygon trough body structure.
Based on said structure design, variable diameter is carried out in order to the interior circular diameter to bottom slot 3, the utility model also mentions
Variable diameter inner sleeve 4 is supplied.
Specifically, variable diameter inner sleeve 4 is regular polygon pipe structure identical with 3 number of edges of bottom slot, the thickness of variable diameter inner sleeve 4
Degree is N*0.5mm, and wherein N is positive integer, and in the present invention, the general value of N is 1 or 2, therefore, the thickness of variable diameter inner sleeve 4
Degree is preferably 0.5mm or 1mm.
Variable diameter inner sleeve 4 is provided with multiple, whole variable diameter inner sleeves 4 coaxially and intussusception is arranged, whole 4 length of variable diameter inner sleeve
Unanimously, variable diameter inner sleeve 4 is successively covered into the variable diameter component for gathering into folds and being formed in this way, length is also a definite value.It is practical new at this
In type, the height of variable diameter inner sleeve 4 is identical as the depth of bottom slot 3 or the height of variable diameter inner sleeve 4 is slightly larger than bottom slot 3
Depth.In an embodiment of the utility model, the height of variable diameter inner sleeve 4 is greater than the depth 2-4mm of bottom slot 3.
It should be understood that in the actual use environment, according to specific service condition and application (bolt or
Nut) difference, the sleeve (sleeve body) there are many different size can be provided, therefore, in the present invention, sleeve body according to
Mainstream compliant sleeve is also equipped with a variety of different models, for example, different length or different-diameter size, expired with this
The requirement of foot difference use environment or application.
After being collapsed into multiple variable diameter inner sleeves 4 together, in two adjacent variable diameter inner sleeves, the variable diameter inner sleeve positioned inside
Lateral surface and be located at the medial surface of variable diameter inner sleeve in outside and offset, can guarantee to cover stack structure between variable diameter inner sleeve 4 in this way
Stability, to improve the reliability that the utility model uses.
By multiple variable diameter inner sleeves 4, successively intussusception forms variable diameter component, and variable diameter component and the inserting of bottom slot 3 cooperate, that is, become
Diameter component is inserted into bottom slot 3, and the medial surface of the lateral surface and bottom slot 3 of variable diameter component offsets, variable diameter component
Central axes and bottom slot 3 central axes be coaxially disposed.
Variable diameter component is inserted into bottom slot 3, the interior circular diameter of such bottom slot 3 will change, according to
Particular condition in use is adjusted the setting quantity of variable diameter inner sleeve 4 on variable diameter component, so that it may meet various different models
The requirement of bolt or nut.
In order to improve the structural strength of variable diameter inner sleeve 4, limit in the present embodiment: variable diameter inner sleeve 4 is metal variable diameter inner sleeve,
Variable diameter inner sleeve 4 is an integral structure.
Specifically, variable diameter inner sleeve 4 is integrally formed by steel alloy or high-carbon steel.
Variable diameter inner sleeve 4 for be inserted into bottom slot 3 or between variable diameter inner sleeve 4 it is mating, in order to avoid become
The problem of diameter inner sleeve 4 falls and influences operation appearance, the utility model have carried out following structure optimization to variable diameter inner sleeve 4:
The contraction opening with its axis parallel is offered in variable diameter inner sleeve 4.Variable diameter inner sleeve 4 is bent to form by high carbon steel sheet, high-carbon steel
The width of plate is identical as the height of variable diameter inner sleeve 4, and the length of high carbon steel sheet is identical as 4 cross section outer rim length of variable diameter inner sleeve, so
High carbon steel sheet is carried out afterwards to be bent to form variable diameter inner sleeve 4, high carbon steel sheet both ends offset and form contraction opening.In non-assembled state
Under, the both ends for forming the high carbon steel sheet of variable diameter inner sleeve 4 have the spacing of 2-4mm, the outside diameter of the variable diameter inner sleeve 4 under the state
Slightly larger than bottom slot 3 or the interior circular diameter of the variable diameter inner sleeve in outside adjacent thereto.In assembly, operator uses hand
The tight variable diameter inner sleeve 4 of finger pressure to shrink opening closure, is then inserted into bottom slot 3 or has been loaded into bottom slot
In variable diameter inner sleeve in 3, after operator looses one's grip, variable diameter inner sleeve 4 itself will appear the trend expanded outward, in this way can
Guarantee the stability that variable diameter inner sleeve 4 inserts.
For the ease of taking out variable diameter inner sleeve 4, the utility model can also open up hook on the medial surface of variable diameter inner sleeve 4
Slot, can very easily variable diameter inner sleeve 4 be pulled out by assembling conjunction pocket for the punch head using external knuckle man.
In the present invention, sleeve body 1 is metal sleeve main body, and sleeve body 1 is an integral structure.Sleeve body
1 can be integrally formed by stainless steel or cast iron.
Specifically, bottom slot 2 is regular quadrangle trough body structure or other regular shapes.
Specifically, bottom slot 3 is regular hexagon trough body structure.
Specifically, bottom slot 3 is fancy trough body structure.
Through said structure design, in Novel sleeve provided by the utility model comprising have sleeve body 1 and become
Diameter inner sleeve 4, variable diameter inner sleeve 4 be provided with it is multiple, and each variable diameter inner sleeve 4 have certain thickness, variable diameter inner sleeve can
It is inserted into bottom slot 3 or other has been loaded into the variable diameter inner sleeve in bottom slot 3.By the variable diameter inner sleeve of multiple intussusceptions
4 are assembled into variable diameter component, and variable diameter component is inserted into bottom slot 3, and the interior circular diameter of such bottom slot 3 will become
Change, is adjusted according to setting quantity of the particular condition in use to variable diameter inner sleeve 4 on variable diameter component, so that it may meet various differences
The bolt of model or the requirement of nut.Novel sleeve provided by the utility model is passed through using a sleeve body 1
