Language is intended merely to describe the purpose of specific embodiment, it is not intended that in limiting the present invention.Used herein
Term " and/or " include the arbitrary and all of combination of one or more relevant Listed Items.
Referring to Fig. 1, the stretching structure 10 of an embodiment includes sleeve 100 and shank 300.Sleeve
One end of 100 is sheathed on one end of shank 300.
Please refer to Fig. 2 and Fig. 3, in present embodiment, sleeve 100 is generally cylindrical in.Sleeve 100
There is socket end 120.It is pointed out that sleeve 100 is not limited to cylindrical shape, it is possible to for rectangle, round platform
Shape or irregularly shaped, as long as the socket end 120 of sleeve 100 is formed with the circle that can be sheathed on shank 300
The accepting groove of cylindricality.Socket end 120 has end face 122.The inwall of sleeve 100 offers chute 140.
In present embodiment, chute 140 has two and is oppositely arranged, in other embodiments, and chute 140
The most one or more.Each chute 140 includes that holding section the 142, first guide part 144 and second is led
To portion 146.
Holding section 142 and end face 122 predetermined distance.Holding section 142 is circumferentially extending along sleeve 100.
First guide part 144 extends from holding section 142 to the direction away from end face 122.In present embodiment, the
One guide part 144 starts from one end of holding section 142 to extend to the direction away from end face 122, and first leads
It is connected with one end of holding section 142 to the one end in portion 144.First guide part 144 is arc, at other
In embodiment, the first guide part 144 is alternatively straight trough.
Second guide part 146 from holding section 142 away from one end of the first guide part 144 near end face 122
Direction extend and run through end face 122.Second guide part 146 is away from one end of end face 122 and holding section
142 are connected.In present embodiment, the second guide part 146 is arc, and holding section 142 is substantially led with second
Tangent to portion 146.It should be noted that the second guide part 146 is not limited to arc, it is possible to for straight trough.
Referring to Fig. 4, shank 300 is generally cylindrical.The sidewall 310 of shank 300 is provided with engaging
Protruding 320.In present embodiment, snap fit tabs 320 has two, and two snap fit tabs 320 are respectively with two
Individual chute 140 is corresponding.It is appreciated that shank 300 is not limited to cylinder, it is possible to for four prism type
Or cylindrical shape, when shank 300 is for four prism type, two snap fit tabs 320 are convexly equipped in two distances respectively
Rib farther out.
Please refer to Fig. 1 to Fig. 6, during assembling, by the most right for two snap fit tabs 320 of shank 300
In two the second guide parts 146, and snap fit tabs 320 should be made to slip into chute 140 along the second guide part 146
Holding section 142.
When needing to shorten shank 300 with sleeve 100 entire length, rotate shank 300 and make snap fit tabs
320 slide into the first guide part 144 one end away from holding section 142 along the holding section 142 of chute 140.
Above-mentioned stretching structure 10 is by arranging by holding section 142 and the first guide part 144 at sleeve 100 inwall
The chute 140 of composition, can conveniently regulate shank 300 and sleeve 100 entire length.Snap fit tabs 320
Can realize significantly when being slid into the first guide part 144 away from one end of holding section 142 by holding section 142
Location.When multiple stretching structures 10 are used in conjunction with, can conveniently regulate the shank of multiple stretching structure 10
300 with sleeve 100 entire length to same length, it is not necessary to measure by other instruments, more convenient.
It is appreciated that the second guide part 146 can omit.Now snap fit tabs 320 is made up of elastomeric material
Or make socket end 120 interference fit of shank 300 and sleeve 100 until snap fit tabs 320 when assembling
Enter the holding section 142 of chute 140.
In other embodiments, each chute 140 includes that multiple holding section 142 and multiple first guides
Portion 144, multiple holding sections 142 are substantially along the axial arrangement of sleeve 100, and multiple first guide parts 144 are with many
Individual holding section 142 is arranged alternately and head and the tail are sequentially connected, and so can extend shank 300 and sleeve 100
The distance of relative telescopic.
In other embodiments, each chute 140 includes the second guide part 146, a multiple holding section
142 and multiple first guide part 144, multiple holding sections 142 are substantially along the axial arrangement of sleeve 100, multiple
First guide part 144 is arranged alternately with multiple holding sections 142 and head and the tail are sequentially connected, so in snap fit tabs
Snap fit tabs 320 can be imported chute 140 by the second guide part 146 when making for non-elastic material by 320
Interior realization is slided.
Additionally, it is possible to make holding section 142 to the first guide part 144 slightly deep, so that snap fit tabs 320 is difficult to
Skid off from holding section 142.
It is appreciated that snap fit tabs 320 is not limited to be arranged at shank 310, it is possible to be arranged at sleeve 100
Inwall, the corresponding inserted terminal that can be contained in sleeve 100 in shank 310 setting, at the side face of inserted terminal
The chute and fitting recess coordinated with snap fit tabs, the now holding section of chute and the end face of inserted terminal are set
Predetermined distance and circumferentially extending along inserted terminal, the first guide part of chute from holding section to away from grafting
The direction of the end face of end extends.
It is appreciated that, it is also possible to multiple stretching structures 10 are sequentially connected with use.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
