Further, described elastic component is spring.
Further, described shaft coupling piece of tightening is spacing by a bearing with the end of shell.
Further, described fixing hole near head end setting is greater diameter than the circular hole of fixing hole.Enter in fixing axle and fix
Kong Hou, spacing using leading portion fixing hole, rear end circular hole is not contacted with fixing hole, it is to avoid stuck.
Further, described fixing axle is splined shaft, n angle axle, tightens shaft-jointed hole and the shape of fixing hole is fitted with fixing axle
Join.
Further, described fixing axle is square shaft, and tightening shaft-jointed hole and fixing hole is square hole.
With respect to prior art, the beneficial effects of the utility model are：
A kind of special extension coupling of tightening axle.Remain the conflict power to front in tightening work, it is to avoid tighten
Axle idle running in tightening work and does not reach work purpose, and delicate structure design is ingenious, with low cost, has good business
Application prospect, is worth promoting on a large scale, have structure take up room little, easy for installation, the advantages of accurate testing, meanwhile, this reality
Circular hole is set after fixing hole with new structure, Circularhole diameter is more than fixing bore dia, reduces the friction of fixing axle and fixing hole,
Occur fixing axle was effectively reduced while spacing with stuck situation.
Brief description
The cross-sectional view that Fig. 1 rotates 90 ° for this utility model.
Wherein, 1- shell, 2- tightens shaft coupling piece, and 3- tightens shaft-jointed hole, 4- fixing axle, 5- elastic component, 6- needle bearing,
7- stretches and holds button set, 8- fixing hole, 9- head end, 10- flange, 11- bayonet socket, 12- catch, 13- bearing, 14- circular hole.
Specific embodiment
With reference to the accompanying drawings and detailed description technical solutions of the utility model are described in further detail：
As shown in figure 1, a kind of special extension coupling of tightening axle, there is a shell 1, connect for tightening axle in shell 1 one end
Part 2, solidifying mandrel connector 2 hollow simultaneously tightens shaft-jointed hole 3, and the described shaft-jointed hole offside of tightening tightening shaft coupling piece 2 welds
There are a fixing axle 4, the outer socket elastic component 5 of fixing axle 4, shell 1 other end holds button set 7 by needle bearing 6 connection one is flexible, Gu
Corresponding flexible button set 7 ends of holding of dead axle 4 have fixing hole 8, and fixing hole 8 aperture is more than fixing axle 4 but less than outside elastic component 5
Footpath, elastic component 5 is stuck in outside fixing hole 8, fixing hole 8 length be more than fixing axle 4 length, elastic component 5 in complete release conditions, Gu
Dead axle 4 also has certain length to coordinate with fixing hole 8, and in fixing hole 8, vacant length is not less than elastic component 5 length, stretches and holds button
Cover 7 remote fixing axle 4 ends and extend outward shell 1 and form square head end 9 and other equipment cooperation.
Further, described shell 1 is easy to and other equipment card tightening shaft coupling piece 2 one end outwardly convex and form a circle
Solid flange 10.
Further, described flexible hold button and cover 7 nearly fixing axle 4 end outers turn up formation bayonet socket 11 to surrounding, and with shell 1
Catch 12 clamping of fixing needle bearing 6.
Further, described elastic component 5 is spring.
Further, described shaft coupling piece 2 of tightening is spacing by a bearing with the end of shell 1.
Further, described fixing hole 8 near head end 9 arranges the circular hole greater diameter than fixing hole.
Further, described fixing axle 4 is splined shaft, n angle axle, tightens shape and the fixing axle of shaft-jointed hole 3 and fixing hole 8
4 adaptations.
Further, described fixing axle 4 is square shaft, and tightening shaft-jointed hole 3 and fixing hole 8 is square hole.
Operation principle of the present utility model is：In real work, the shaft-jointed hole 3 of tightening tightening shaft coupling piece 2 connects front end
Device for screwing up, specific tightening piece is connected by head end 9, in order to other external equipments cooperation, on shell 1 arrange flange 10
It is easy to cooperation to fix, tighten device for screwing up in work and apply pressure to tightening shaft coupling piece 2, lead to spring deformation, so that solid
Dead axle 4 stretches into and drives head end 9 to rotate in fixing hole 8, and spring makes head end 9 remain to the flexible button set 7 applying pressure that holds simultaneously
Certain conflict power, it is to avoid dally, shell 1 is connected by needle bearing 6 between button set 7 with flexible holding, and can arbitrarily rotate,
Be easy to fix, simultaneous retractable hold button cover 7 nearly fixing axle 4 end outers to surrounding turn up formation bayonet socket 11, and with shell 1 fix needle roller
Catch 12 clamping of bearing 6, makes the flexible button that holds cover, fixing hole 8 more firm to geo-stationary, structure before and after 7 and shell 1 holding
Aperture is more than fixing axle 4 but is less than elastic component 5 external diameter, and elastic component 5 is stuck in outside fixing hole 8, and fixing hole 8 length is more than fixing axle
4 length, in complete release conditions, fixing axle 4 also has certain length to coordinate with fixing hole 8 to elastic component 5, and vacant in fixing hole 8
Length is not less than elastic component 5 length, thus keep head end 9 can under any state of spring with tighten shaft coupling piece 2 and coordinate
Rotate, meanwhile, spring-compressed to fixing axle during the limit 4 and fixing hole 8 also can be good at coordinating, thus coordinating different conflict powers
Demand, in an embodiment of the present utility model, fixing hole rear end is changed to the bigger circular hole in aperture, fixing axle enter fix
Kong Hou, spacing using leading portion fixing hole, rear end circular hole is not contacted with fixing hole, it is to avoid stuck.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to
In this, any change or replacement expected without creative work, all should cover within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be defined by the protection domain that claims are limited.
