Taper surface.
It is preferred that, distance on the right side of the cutting plane to cylinder cushion block is between 5.07 millimeters to 5.13 millimeters, described
The transverse gage of cylinder cushion block is between 2.05 millimeters to 2.15 millimeter.
It is preferred that, a diameter of between 1.67 millimeters to 1.7 millimeters, a diameter of 1.89 milli of the threaded rod of the polished rod
Rice is between 1.98 millimeters.
It is preferred that, it is institute between 2.9 millimeters to 3.0 millimeters the distance between on the right side of the left side of the polished rod to threaded rod
It is 8.06 millimeters to 8.13 millimeters to state the distance on the right side of cutting plane to threaded rod.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model can be threadedly coupled by the setting of threaded rod with the screwed hole on connector, the setting of polished rod
The surface of cylinder cushion block and the intimate surface contact of connector can be made, enhance that cylinder cushion block is connected with connector is close
Property, the surface of nut is set to circular arc taper surface so that the inside of the deep enough connector of nut energy closely connects with connector
Touch, enhance the compactness that nut is connected with connector, enhance the steadiness that screw is connected with connector, add earphone
Aesthetic property.
2nd, the utility model makes nut go deep into behind connector inside keeping and connector surface by the setting of cutting plane
Level, increases the aesthetic property of connector, while the convenient cross engagement groove of Surface Machining in cutting plane, passes through cross knot
The convenient dismounting position with extracting tool of setting for closing groove and stage portion carries out clamping, facilitates the rotation of nut, convenient to screw
Dismantled and installed.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the left view of the utility model structure.
In figure：1 nut, 2 cutting planes, 3 cross engagement grooves, 4 stage portions, 5 cylinder cushion blocks, 6 polished rods, 7 threaded rods.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1-2, a kind of screw on earphone, including nut 1 are referred to, the left side of nut 1 is provided with cutting plane
