The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of bull telescopic sleeve spanner, comprise a plurality of collet heads, and described collet head is made of the inner sleeve outer sleeve outer with being sheathed on described inner sleeve, also comprises pedestal; The middle part of described pedestal has the handle socket of up/down perforation; Described inner sleeve is fixed or the removable side that is fixed on described pedestal.
For the collet head that more different specification sizes are arranged can be replaced use, to satisfy requirement widely, a kind of optimized technical scheme is: an end of above-mentioned inner sleeve is provided with notch, described pedestal side be provided with at least two can with the connection-peg of the corresponding grafting of described notch.
Spacing convenient when being plugged on the pedestal for collet head, and dismounting is more convenient, and a kind of optimized technical scheme is: the cross section of above-mentioned connection-peg is rectangle, and described connection-peg is provided with hoodle; Be provided with in the described notch can with the groove of the corresponding engaging of described hoodle.
In order to make the structure of this box spanner more reasonable, to use conveniently, a kind of optimized technical scheme is: being shaped as of said base is cylindrical, and described connection-peg has three to five, along circumferentially equidistantly distributing of described pedestal.
In order to distinguish the collet head of different specification size more easily, a kind of optimized technical scheme is: above-mentioned inner sleeve is provided with the annulus portion for the sign sleeve dimensions.
When making that outer sleeve is in running order, spacing more accurate, convenient; When outer sleeve is in off working state, can arbitrarily not slide, a kind of optimized technical scheme is: the outer wall upper edge of above-mentioned outer sleeve circumferentially has annular groove, is provided with the through hole that runs through described outer sleeve barrel in the described annular groove; Be arranged with the springs circle that is positioned at described annular groove on the described outer sleeve; Described springs circle is provided with the spacing hole relative with described lead to the hole site, and the outer wall of described inner sleeve is provided with the pit relative with described lead to the hole site; Be provided with steel ball in the described through hole, a side of described steel ball is arranged in described spacing hole, and when described outer sleeve slides to an end of described inner sleeve when in running order, the opposite side of described steel ball is arranged in described pit.
When making that outer sleeve is in running order, spacing more accurate, convenient; When outer sleeve is in off working state, can arbitrarily not slide, another kind of optimized technical scheme is: the inwall upper edge of above-mentioned outer sleeve circumferentially has annular notches; The outer wall of described inner sleeve is provided with the stopper slot that arranges along circumferentially; Be arranged with the ring-spring circle that is positioned at described annular notches on the described inner sleeve; One side of described stopper slot is provided with the inclined-plane that slides into, skids off for the ring-spring circle; When described outer sleeve slides to an end of described inner sleeve when in running order, described ring-spring circle is arranged in stopper slot.
The utlity model has positive effect: bull telescopic sleeve spanner of the present utility model is combined into independently telescopic collet head with the sleeve of two kinds of specifications, and the collet head with one group of different size combines again, and volume is small and exquisite, and is easy to carry.When this box spanner uses, can be directly with the collet head on the pedestal side as rotating handles, also can in the handle socket of pedestal, insert handle, by the turnbarrel spanner, tighten easily and unscrew hex bolts, it is very convenient to operate.
