As shown in fig. 2, the utility model relates to an one-way sharp-angled tooth sleeve, it includes hollow sleeve body 1, sleeve body 1 and nut contact one end are the dismantlement end, the inside wall of sleeve body 1 that is located its dismantlement end is equipped with sharp-angled tooth subassembly, sharp-angled tooth subassembly includes a plurality of sharp-angled teeth 2 that evenly set up along sleeve body 1 inside wall circumference, arbitrary sharp-angled teeth 2 all have the rigidity flank of tooth, can avoid this one-way sharp-angled tooth sleeve when unscrewing the nut, the rigid contact takes place between sharp-angled teeth 2 and the nut and takes place deformation; the pointed ends of the sharp teeth 2 on the same sharp tooth component are arranged along the inner side wall of the sleeve body 1 in a clockwise/anticlockwise deflection mode, namely the arrangement mode of all the sharp teeth 2 on the sharp tooth component is the same as the arrangement mode of the ratchets on the ratchet wheel, and when the sleeve body 1 is rotated in a certain direction, the sharp teeth 2 can be clamped around the nut, so that the nut can be unscrewed well.

In order to better clamp the sharp teeth 2 around the nut, furthermore, the tips of the sharp teeth 2 are prismatic or conical, and when the tips are conical, the action surfaces of the sharp teeth 2 and the nut are smaller, and the sharp teeth can also be better clamped around the nut.

In order to improve the overall working stability, the sharp-tooth assemblies are further provided with a plurality of groups, and the plurality of groups of sharp-tooth assemblies are arranged side by side along the length direction of the sleeve body 1. Of course, the overall height of the plurality of sets of tine assemblies should match the height of the sides of the nut.

To improve the overall stability, further, the deflection directions of the tines 2 of two adjacent sets of tine assemblies are the same.

In order to better adapt to the specification of the nut, further, the inner diameter D of the detaching end of the sleeve body 1 can be 8mm, 12mm, 14mm or 16 mm.

In order to more conveniently clamp the sharp teeth 2 of the sharp teeth assembly around the nut when the sleeve body 1 is disassembled and sleeved on the nut, the inner side wall of the sleeve body 1 is further provided with a groove 3, and the sharp teeth assembly is arranged in the groove 3. Due to the arrangement of the grooves 3, the length of the sharp teeth 2 can be correspondingly lengthened, when the dismounting end of the sleeve body 1 is sleeved on the nut, the extending parts of the sharp teeth 2 at the positions of the grooves 3 are clamped around the nut, and therefore the dismounting of the nut is facilitated.

Certainly, in order to realize more smoothly with sharp tooth 2 card on the nut, further, still be provided with the spring between sharp tooth 2 and the sleeve body 1, when sending into sleeve body 1 dismantlement end with the nut, the nut top surface takes place to contact with sharp tooth 2 and makes it return and return partly, continues the in-process of sending into the nut, sharp tooth 2 because the effort of spring and the card that deepens more around the nut, alright better realization like this the utility model discloses the purpose to unscrew this nut smoothly.

For better screwing sleeve body 1, further, sleeve body 1 other end is equipped with the connection roof, has seted up connecting hole 4 on the connection roof, and the spanner alright be connected with sleeve body 1 through connecting hole 4 to it makes its emergence rotation to sleeve body 1 application of force more easily.

At specific working process, go into around the nut with 1 card of sleeve body, then make sleeve body 1 rotate toward a fixed direction according to sharp pointed tooth most advanced direction of deflection, and sharp pointed tooth subassembly can be fine card around the nut to can be fast easily unscrew the nut, reach the utility model discloses a purpose.

The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all the technical solutions falling within the scope of the present invention, are within the protection scope of the present invention.
