Description
Technical field
The utility model relates to the instrument that mechanical field uses, and especially a kind ofly can will lose the on-slip sleeve that the bolt of corner angle or nut take off from screw or screw rod.
Background technology
In the machinery production field, especially in machining or job site, often running into bolt is screwed in the screw, owing to used of a specified duration or misoperation, cause the distortion of head of screw or nut rounding, cause can't with conventional tool bolt is taken out from screw or with nut from the problem that bolt takes off, wasted the time, affected job schedule adversely.
Summary of the invention
The purpose of this utility model be at after the distortion of head of screw or nut rounding can't with conventional tool bolt is taken out from screw or with nut from the problem that bolt takes off, a kind of on-slip sleeve that can easily the bolt of having damaged be taken out from screw or nut is taken off from bolt is provided.
On-slip sleeve described in the utility model comprises sleeve body.Sleeve body is hollow form.One end of sleeve body is provided with the pass that matches with the standard spanner.The other end of sleeve body is provided with tapered endoporus.The conical surface of cone-shaped inner hole is made of spiral lobe type groove.
The pass that sleeve body one end and standard spanner match is hexagonal hole or cubic hole.
The spiral helicine lobe type of sleeve body other end cone-shaped inner hole groove is six or four.
The spiral helicine lobe type of sleeve body cone-shaped inner hole groove is left-handed or dextrorotation.
During use, the cone-shaped inner hole with spiral helicine lobe type groove is enclosed within on the bolt head of having damaged or nut, exerts pressure a little, just bolt or the nut of having damaged can be taken out with standard spanner turnbarrel.
The utility model simple structure, easy to use.
