Embodiment
For the ease of understanding the present invention, the below is described more fully the present invention with reference to relevant drawings.Provided first-selected embodiment of the present invention in the accompanying drawing.But the present invention can realize with many different forms, be not limited to embodiment described herein.On the contrary, providing these embodiments' purpose is to make to disclosure of the present invention more thoroughly comprehensively.
Need to prove that when element is called as " being fixedly arranged on " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be to be directly connected to another element or may to have simultaneously centering elements.Term as used herein " vertical ", " level ", " left side ", " right side " and similar statement are just for illustrative purposes.
Unless otherwise defined, the employed all technology of this paper are identical with the implication that belongs to the common understanding of those skilled in the art of the present invention with scientific terminology.Employed term is not intended to be restriction the present invention just in order to describe the purpose of specific embodiment in specification of the present invention herein.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
See also Fig. 1, the shrinking structure 10 of a mode of execution comprises sleeve 100 and shank 300.One end of sleeve 100 is sheathed on an end of shank 300.
Please consult simultaneously Fig. 2 and Fig. 3, in the present embodiment, sleeve 100 is roughly cylindric.Sleeve 100 has socket end 120.It is cylindric to it is pointed out that sleeve 100 is not limited to, and also can be rectangle, frustoconic shape or irregularly shaped, as long as the socket end 120 of sleeve 100 is formed with the columniform accepting groove that can be sheathed on shank 300.Socket end 120 has end face 122.The inwall of sleeve 100 offers chute 140.
In the present embodiment, chute 140 has two and be oppositely arranged, and in other embodiments, chute 140 also can be one or more.Each chute 140 comprises engagement portion 142, the first guide portion 144 and the second guide portion 146.
The second guide portion 146 from the engagement portion 142 away from an end of the first guide portion 144 to extending near the direction of end face 122 and running through end face 122.The second guide portion 146 is connected with engagement portion 142 away from an end of end face 122.In the present embodiment, the second guide portion 146 is arc, and engagement portion 142 is substantially tangent with the second guide portion 146.Need to prove that the second guide portion 146 is not limited to arc, also can be straight trough.
See also Fig. 4, shank 300 is roughly cylindric.The sidewall 310 of shank 300 is provided with snap fit tabs 320.In the present embodiment, snap fit tabs 320 has two, and two snap fit tabs 320 are corresponding with two chutes 140 respectively.It is cylindrical to be appreciated that shank 300 is not limited to, and also can be four prism type or cylindrical shape, when shank 300 during for four prism type two snap fit tabs 320 be convexly set in respectively two distant ribs and get final product.
Please consult simultaneously Fig. 1 to Fig. 6, during assembling, two snap fit tabs 320 of shank 300 are corresponded respectively to two the second guide portions 146, and snap fit tabs 320 is got final product along the engagement portion 142 that the second guide portion 146 slips into chute 140.
When need shortening shank 300 with sleeve 100 entire length, rotate shank 300 and make snap fit tabs 320 slide into the first guide portion 144 along the engagement portion 142 of chute 140 to get final product away from an end of engagement portion 142.
Above-mentioned shrinking structure 10 by in sleeve 100 inwall settings by the chute 140 that engagement portion 142 and the first guide portion 144 form, can conveniently regulate shank 300 and sleeve 100 entire length.Snap fit tabs 320 can realize obvious location when sliding into the first guide portion 144 away from an end of engagement portion 142 by engagement portion 142.During a plurality of shrinking structures 10 common the use, the shank 300 that can conveniently regulate a plurality of shrinking structures 10 and sleeve 100 entire length need not to measure by other instruments to same length, and are comparatively convenient.
Be appreciated that the second guide portion 146 can omit.Snap fit tabs 320 was made by elastic material or was made shank 300 and the socket of sleeve 100 hold 120 interference fit until snap fit tabs 320 enters the engagement portion 142 of chute 140 gets final product in when assembling this moment.
In other embodiments, each chute 140 comprises a plurality of engagement portions 142 and a plurality of the first guide portion 144, a plurality of engagement portions 142 are generally along the axially-aligned of sleeve 100, a plurality of the first guide portions 144 are arranged alternately with a plurality of engagement portions 142 and head and the tail link to each other successively, can prolong like this shank 300 and sleeve 100 relative flexible distances.
In other embodiments, each chute 140 comprises second guide portion 146, a plurality of engagement portion 142 and a plurality of the first guide portion 144, a plurality of engagement portions 142 are generally along the axially-aligned of sleeve 100, a plurality of the first guide portions 144 are arranged alternately with a plurality of engagement portions 142 and head and the tail link to each other successively, like this can be by the second guide portion 146 with the 140 interior realizations slips of snap fit tabs 320 importing chutes when snap fit tabs 320 is made for non-elastic material.
In addition, also can make engagement portion 142 to the first guide portions 144 slightly dark, skid off so that snap fit tabs 320 is difficult for from the engagement portion 142.
Be appreciated that, snap fit tabs 320 is not limited to be arranged at shank 310, also can be arranged at the inwall of sleeve 100, corresponding arranges the bayonet end that can be contained in sleeve 100 at shank 310, the chute and the fitting recess that cooperate with snap fit tabs in the side face setting of bayonet end get final product, this moment chute be separated by intended distance and along the circumferential extension of bayonet end of the end face of engagement portion and bayonet end, the first guide portion of chute gets final product to the direction extension away from the end face of bayonet end from the engagement portion.
Be appreciated that also and a plurality of shrinking structures 10 can be connected use successively.
The above embodiment has only expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
