The specific embodiment
Below, hereby with regard to structure content of the present invention and feature thereof, and coordinate graphic being described in detail as follows, believe and can, with regard to the effect of content of the present invention and generation thereof, do further to understand.
Refer to Fig. 1
shown in Fig. 4, wherein, the present invention includes an outer sleeve 1 and an inner sleeve group 2, wherein:
One outer sleeve 1, it is one can wear hollow cylinder 11 wherein for inner sleeve group 2, and in this cylindrical shell 11Nei one end, ratchet section 12 is set, in this ratchet section 12, axial plane and axial plane intersection are provided with concave arc 121, in this cylindrical shell 11, be provided with a limited impression 13, and in this cylindrical shell 11, differ from ratchet Duan12 one end one tool-joint 14 is set, this outer sleeve 1 external diameter is with respect to a snap joint 15 is set on tool-joint 14 position, the interior sheathed flexible member 151 of this snap joint 15, 151 of this flexible members are sheathed on outer sleeve 1, and this snap joint 15 is subject to one to be limited in locating ring 152 on outer sleeve 1 and spacing,
One inner sleeve group 2, with an axostylus axostyle 21, be arranged in the hollow cylinder 11 of outer sleeve 1, this axostylus axostyle 21Shang one end arranges a defining flange 211, one limited impression 212 is set on axostylus axostyle 21, a sheathed locating ring 213 on this limited impression 212, 213 of this locating rings can be limited in the limited impression 13 of outer sleeve 1, this axostylus axostyle 21 is positioned in the hollow cylinder 11 of outer sleeve 1, on this axostylus axostyle 21, sequentially for a flexible member 22 and inner sleeve 23, wear, the external diameter of this inner sleeve 23 is ratchet 231, this ratchet 231 is that can be sheathed on the interior mutual fit of ratchet section 12 of outer sleeve 1 spacing, and this inner sleeve 23 is to be arranged on axostylus axostyle 21 by an axis hole 232, and the internal diameter of this axis hole 232 is greater than the external diameter of axostylus axostyle 21 and be less than the maximum outside diameter of axostylus axostyle 21 upper limit flanges 211, the drive rod 233 of moulding majority outward on the ratchet 231 of this inner sleeve 23, this drive rod 233 is to be sheathed in the concave arc 121 arranging in outer sleeve 1 ratchet section 12 and to be parallel to be oppositely arranged, this drive rod 233 is circular, square or polygonal body of rod.
In this way, outer sleeve 1 is positioned to sheathed this flexible member 151 and snap joint 15 on the relative external diameter of tool-joint 14, by locating ring 152, this snap joint 15 is limited on outer sleeve 1 again, take and reach that (snap joint of this part is general prior art with the Quick connecting of hand-operated tools or electric tool or dismounting, and non-main contents of the present invention, therefore do not repeat them here), and now, sequentially by the inner sleeve of inner sleeve group 2 23, flexible member 22 is sheathed on axostylus axostyle 21, and on the limited impression 212 of axostylus axostyle 21 sheathed this locating ring 213, again by the sheathed hollow cylinder 11 that enters outer sleeve 1 of this axostylus axostyle 21, and this locating ring 213 is inserted in the limited impression 13 in hollow cylinder 11 and locates, and this inner sleeve 23 is limited in hollow cylinder 11, refer to Fig. 5, shown in Fig. 6, when wish is locked or is unclamped the nut 3 of the size that conforms to inner sleeve 1, the drive rod of inner sleeve 23 233 is inserted in to this nut 3, make the internal diameter of drive rod 233 be supported the axle limit of being located at nut 3, and when the hand-operated tools of tool-joint end or the electric tool application of force, the ratchet 231 of this inner sleeve 23 because of the interior mutual fit of the ratchet section 12 with outer sleeve 1 spacing, and this drive rod 233 is to be sheathed in the concave arc 121 arranging in outer sleeve 1 ratchet section 12, rotating with the rotation of outer sleeve 1, and can be subject to the support of outer sleeve 1 ratchet section 12 stressed, and can reach the effect that can lock or unclamp this nut 3.
And when wish is locked or unclamped the nut 4 of this large-size, refer to Fig. 7, shown in Fig. 8, outer sleeve 1 is inserted in to nut 4, now the axle limit external diameter of nut is the relative internal diameter that is greater than 233 of inner sleeve 2 drive rods, be with, when being inserted in nut 4, nut 4 by drive rod 233 toward the interior propelling movement of hollow cylinder 11, drive rod 233 is presented toward inside contracting displacement, and make this nut 4 can be subject to the driving of ratchet section 12 ratchets of outer sleeve 1, and the effect that reaches locking or unclamp this nut 4, and when locking or unclamping after this nut 4, this inner sleeve 23 can be subject to the elastic returning of flexible member 22, and get back to original position, can implement again to meet inner sleeve 23 sizes nut 3 locking or unclamp.
So, the present invention is limited in outer sleeve 1 by inner sleeve group 2, and makes the inner sleeve 23 of inner sleeve group 2 be able to inside contract displacement in the hollow cylinder 11 of outer sleeve 1, to provide the sleeve of two kinds of different sizes to use, and can reach really and location easily.
The invention described above is only with most preferred embodiment explanation for example, and to being familiar with the personnel of this skill, when carrying out each change, but this change all should be included in spirit of the present invention and category.
In sum, the present invention is limited in outer sleeve by inner sleeve group, and makes the inner sleeve of inner sleeve group be inside contracted displacement, to provide the sleeve of two kinds of different sizes to use, and can reach really and location easily, no matter it is structural change, or be the enhancement in effect, all unquestionable, and the present invention does not see publication before application, also unexposed use, has met patent application requirement in fact, proposes patent application in accordance with the law.
