Embodiment

As shown in the figure, basically, interference component of the present utility model is combined by a male member 1 and one recessed 2.

Wherein, male member 1 is formed in one, and is good with high-abrasive material such as metal, only not as limit.Its central tool one axis hole 11 passes through for pivot, on its one side, can be provided with for external member A, shown in the utility model embodiment, is tenon, only not as limit.Cover or the slow effect of raising for making it can obtain the slow of predetermined angle of the present utility model, on the bulge loop 12 of circle, get the outer convex surface 13 that isogonism is provided with, and the narrower interior convex surface 14 of subtend width, and two outsides of outer convex surface 13, then link with inclined-plane between the drop on 15 of outer convex inclined planes and bulge loop 12 surfaces, interior convex surface 14 both sides are provided with the identical interior convex inclined plane 16 of tool.

Recessed 2 it be cylindrical cross section, its central tool one embedding hole 21 is for external, and, then establish the only larger-size outer concave surface 22 of a depression, its embedding mutually corresponding to aforementioned outer convex surface 13 places, identical, then corresponding to convex surface 14 places in aforementioned then correspondence one inner concave 23 is set, and the both sides of outer concave surface 22 also are provided with the face 24 that concaves outward, the both sides of inner concave 23 also are provided with indent inclined-plane 25, respectively the trend on this inclined-plane is identical, has the effect of comparatively connecting airtight.

And it is unlikely for setting the location in order to make in crossing 90 degree to the supplementary angle that is tending towards presetting, therefore, outer convex surface 13 extends to outer rim B, that is wider width, interior convex surface 14 is then for extending to the outer edge, and do not protrude with one section of outer rim tool and be to be the area B of same upper surface with bulge loop 12, in the same manner, the periphery of recessed 2 inner concave 23, also one section zone C that does not cave in of tool.

Please consult accompanying drawing again, the utility model is when implementing, male member 1 is repeatedly put for subtend with recessed 2, and be same axle center but respectively depend on external object, as shown in Figure 2, when both are chimeric, be 0 when spending, for covering, this moment, outer convex surface 13 fell in the outer concave surface 22 lid, and interior convex surface 14 falls in the inner concave 23 with respect to body.As shown in Figures 3 and 4, when male member 1 rotation, then because of displacement relation, outer convex surface 13 and the interior convex surface 14 of this moment promptly begins to produce interference with concave face 24 and indent side 25 etc. outward, and make and lift component, the object and the body that promptly link male member 1, the object that promptly links recessed 2 produces friction, and can be the location via packing, and see also later Fig. 5 and Fig. 7 in crossing 90 degree, still be in interference state, even arrive complementary angle, (as preset angle is 0 to 15 degree, then be that 165 degree are to 180 degree) time, because outer convex surface 13 is bigger than inner concave 23, so unlikely falling into, so still be in interference state.
