Abstract

The utility model discloses a kind of variable-length sleeve extension rod, it comprises the antitorque stud of slide bar, sleeve pipe, positioning stud and guiding, slide bar is assemblied in sleeve pipe, slide bar has gathering sill, positioning stud and the antitorque stud of guiding are threaded connection and are assemblied on sleeve pipe, and the head of the antitorque stud that leads is inserted in gathering sill.The utility model realizes the adjustable in length of sleeve extension rod, thus reduces the quantity of tool box inner sleeve extension bar.

Description

Variable-length sleeve extension rod
Technical field
The utility model relates to a kind of sleeve extension rod, particularly relates to a kind of variable-length sleeve extension rod.
Background technology
Along with expanding economy, human cost is increasingly surging, also promotes the efficiency requirements of instrument thereupon.Box spanner in use, in order to can far-reaching or narrow place be arrived, must with sleeve extension rod with the use of.The length of current sleeve extension rod is all fixing, when sleeve uses, must be equipped with the sleeve extension rod of different length in tool box, add the weight in tool box, changes different sleeve extension rods and also wastes the activity duration.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of variable-length sleeve extension rod, and it realizes the adjustable in length of sleeve extension rod, thus reduces the quantity of tool box inner sleeve extension bar.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of variable-length sleeve extension rod, it is characterized in that, it comprises the antitorque stud of slide bar, sleeve pipe, positioning stud and guiding, slide bar is assemblied in sleeve pipe, slide bar has gathering sill, positioning stud and the antitorque stud of guiding are threaded connection and are assemblied on sleeve pipe, and the head of the antitorque stud that leads is inserted in gathering sill.
Preferably, described gathering sill is vee gutter.
Preferably, described gathering sill is dovetail groove.
Positive progressive effect of the present utility model is: the utility model realizes the adjustable in length of sleeve extension rod, thus reduces the quantity of tool box inner sleeve extension bar.Sleeve extension rod adjustable in length will inevitably decrease changes sleeve extension rod number of times, saves the time changing sleeve extension rod, increases operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model variable-length sleeve extension rod.
Fig. 2 is the sectional view in the A-A direction at positioning stud place along Fig. 1.
Detailed description of the invention
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model variable-length sleeve extension rod comprises slide bar 1, sleeve pipe 2, positioning stud 3 and the antitorque stud 4 that leads, slide bar 1 is assemblied in sleeve pipe 2, slide bar 1 has gathering sill 5, positioning stud 3 and the antitorque stud 4 of guiding are threaded connection and are assemblied on sleeve pipe 2, and the head of the antitorque stud 4 that leads is inserted in gathering sill 5.Gathering sill is vee gutter or dovetail groove, as long as meet guiding and antitorque function.
When positioning stud 3 unclamps, the adjustable in length of this variable-length sleeve extension rod, slide bar 1 can slide in the axial direction in sleeve pipe 2; And after positioning stud 3 screws, slide bar 1 is relative with sleeve pipe 2 fixing, the length of variable-length sleeve extension rod is locked.When assembling and positioning stud 3 and the antitorque stud 4 of guiding, the head of antitorque stud of guaranteeing to lead must be inserted in gathering sill, to stop relatively rotating between slide bar 1 and sleeve pipe 2.The utility model realizes the adjustable in length of sleeve extension rod, thus reduces the quantity of tool box inner sleeve extension bar.Sleeve extension rod adjustable in length will inevitably decrease changes sleeve extension rod number of times, increases operating efficiency.
The utility model variable-length sleeve extension rod has following characteristics: one, the utility model adopts shift sleeve structure, and the length realizing sleeve extension rod regulates arbitrarily within the specific limits.Slide bar is assemblied in sleeve pipe, and slide bar has gathering sill, and positioning stud and the antitorque stud of guiding are threaded connection on sleeve pipe, and the head of the antitorque stud that leads is inserted in gathering sill; When positioning stud unclamps, slide bar can slide in the axial direction in sleeve pipe, and after positioning stud screws, slide bar is relative with sleeve pipe fixing, and the length of sleeve extension rod is locked.Two, the head of positioning stud and the antitorque stud of guiding is inserted in gathering sill, stops relatively rotating between slide bar and sleeve pipe, transmitting torque.Three, the utility model in use, because the gathering sill of slide bar and positioning stud, the antitorque stud of guiding bear large turning moment, long-time use will inevitably cause comparatively galling, therefore gathering sill surface has to pass through cure process, the part of positioning stud and guiding antitorque stud insertion gathering sill also will through Surface hardening treatment.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model cover fall into appending claims and equivalent thereof scope in various remodeling and change.
