400,300 outside of wiring ontology is sheathed on, casing 400 further includes 401 and second casing 402 of first sleeve, the second casing 402
At line end 301, and the outside of first sleeve 401 is sheathed on, first sleeve 401 is directly sleeved on wiring in the present embodiment
On ontology 300, wiring ontology 300 can be in first sleeve 401 by the traction piece on vehicle, and for example brake pedal is drawn herein
It is moved in first sleeve 401 afterwards, so as to fulfill the braking to vehicle, further, the second casing 402 is sheathed on first sleeve
It on 401 and can slide on, can realize the more of first sleeve 401 by way of the docking of second casing 402 at both ends
Section connection, and after the completion of docking wiring ontology 300 can be pulled in the first sleeve 401 it is dynamic.Wherein line end 301 is wiring
The part that 300 one end upper edge internal diameter of ontology expands outwardly further includes the first groove 301a, convex block 301b, fixed pin 301c, limit
Position block 301d and shrapnel 301e；Several first groove 301a (in the present embodiment as a preferred embodiment, it is six) annular rows
Row are set on the edge anchor ring of line end 301, and fixed pin 301c and convex block 301b is set to the side of end 301, and limits
Block 301d is connect with fixed pin 301c, and shrapnel 301e is connect with convex block 301b.And further include the second groove 302a, revolution space
302b, mounting hole 302c, limiting slot 302d and to hook 302e, the second groove 302a is corresponding with the first groove 301a to be set
It puts, is also set on the edge anchor ring for the part 302 that is screwed on for six annular arrays, revolution space 302b is set to the part 302 that is screwed on
One side, the another side of limiting slot 302d and the part 302 that may be contained within being screwed on to hook 302e, and mounting hole 302c is set to
Be screwed on the center of part 302, runs through and connects revolution space 302b and limiting slot 302d.The above-mentioned each component of further instruction corresponds to
Position relationship and state in which, wherein fixed pin 301c is inserted into mounting hole 302c, and the limit of fixed pin 301c ends
Position block 301d is located at limiting slot 302d and completes limiting, and convex block 301b is located in revolution space 302b at this time；And convex block 301b is with revolving
It is adaptable sector structure to turn space 302b, the shrapnel 301e under original state can one end contradict convex block 301b, the other end
Revolution space 302b side walls are contradicted, convex block 301b extrusion elastics 301e deformations during stress, convex block 301b can be empty in rotation at this time
Between rotate in 302b, then during this, shrapnel 301e deformed upon under the action of rotary force therefore its restore with deformation
Trend realizes the reset in disassembly process after docking.
Wherein first sleeve 401 further includes the casing end 401a being sheathed in line end 301, and casing end 401a packets
Raised line 401a-1 and sliding slot 401a-2 is included, sliding slot 401a-2 is uniformly arranged on the surface of described sleeve pipe end 401a successively, convex
401a-1 is uniformly arranged on the inner surface of casing end 401a successively, and raised line 401a-1 is corresponded to and is located at two casing end 401a
Between, in the present embodiment with reference to shown in Fig. 9, raised line 401a-1 and sliding slot 401a-2 are respectively alternatively arranged for three correspondences.Further
, with reference in Figure 13~14, the second casing 402 is sheathed on the 401a of casing end, and also sets up locked component therebetween
500, locked component 500 includes elastic component 501, locking ring 502 and locking bar 503,501 one end quilt cover pipe end of elastic component
The end limiting of 401a, one end is connect with locking ring 502, can be spring；Locking bar 503, which is arranged in order, is set to locking ring
502 inner surface.It is to be understood that being sheathed on the original state in line end 301 in casing end 401a in the present embodiment
Under, it is shifted to install between the first groove 301a and the second groove 302a, and raised line 401a-1 is located in the first groove 301a, and its
Non-recessed portion limits in the second groove 302a that end is misplaced, this kind of set-up mode can reach following effect：First, set
Limiting between pipe end 401a and line end 301, and do not limited between part 302 with being screwed on, it can realize line end 301 and rotation
The relative rotation of fitting 302；Second is that line end 301 is limited in the initial state by non-recessed portion limiting in the second groove 302a
It cannot be rotated by traction.
In order to realize when shrapnel 301e is depressed into the limit in the present embodiment, locking bar 503 enters in the second groove 302a
Locking is completed, locking herein is set relative to the restoring force that shrapnel 301e has, though shrapnel 301e has in the locked state
Restoring force but be locked out restore deformation, the shrapnel 301e compressed after unlocking be not bound restore deformation, realize
It is reset to original state.Specifically, with reference in Figure 10, in the initial state, sliding slot 401a-2 is corresponding with the first groove 301a to be connected
Logical, the two forms lock slots 504, and locking bar 503 is adapted and is set in lock slots 504, and end is misplaced second recessed
Non-recessed portion limits in slot 302a, is extruded the limit when turning to shrapnel 301e, locking bar 503 is pushed to enter the second groove
The rotation to line end 301 and the relative rotation of part 302 that is screwed on is completed in 302a.
With reference to shown in Figure 15~18, the installation process of adapter assembly A of the present invention provided herein：Specifically, initial shape
State shifts to install between the first groove 301a and the second groove 302a；Second state is that 300 both ends of wiring ontology can pass through
The part 302 that is screwed on docks, and in the initial state, being open to hook 302e for both ends is oppositely oriented, and when being screwed on, part 302 rotates
When, until both ends mutually contradict limiting to hook 302e and can not rotate；When in the second condition, phase can occur for line end 301
For being screwed on, part 302 rotates, and shrapnel 301e is increasingly compressed to the limit, is the third state：In reference Figure 14, lock slots 504
It releases and shifts to install between the second groove 302a, the two forms second channel M, and casing end 401a is pushed to cause locking bar 503
Locking is completed in into the second groove 302a；With reference in Figure 15, dislocation is released between the first groove 301a and the second groove 302a
Setting, the two form first passage S, and raised line 401a-1 can be free to slide in channel S；With reference to Figure 16~17, the second casing
402 also divide into inner tube 402a and outer tube 402b, inner tube 402a outer surfaces setting internal thread 402a-1, and outer tube 402b inner surfaces
External screw thread 402b-1 and end setting block 402b-2 is set, structure is threaded by inner and outer surfaces and completes both ends second
The docking of casing 402, when the second casing of both ends 402 is completed to dock, block 402b-2 and casing end 401a are mutually contradicted pair
The restoring force that elastic component 501 has after deforming upon is limited so that elastic component 501 is constantly in tensional state, works as needs
During dismounting, rotating the second casing 402 with opposite direction during installation opens its helicitic texture, passes through shrapnel 301e and elastic component
501 complete to reset.
It should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to preferable
The present invention is described in detail in embodiment, it will be understood by those of ordinary skill in the art that, it can be to the technology of the present invention
Scheme is modified or replaced equivalently, and without departing from the spirit and scope of technical solution of the present invention, should all be covered in this hair
In bright right.
