Further, the notch of described the first noumenon groove, the second body groove and the 3rd body groove all takes the form of inclined plane, and the notch angle of inclination of each body groove is 18 °-20 °.
Further, described first stopper slot, the second stopper slot and all T-shaped shape of the 3rd stopper slot.
Further, be provided with the 3rd groove bottom the vallecular cavity in described 3rd spacing half groove, the 3rd groove is equal with the groove depth of second groove.
Contrast the deficiencies in the prior art, the beneficial effect that the technical solution of the utility model is brought:
1. the earpiece of the application mirror bar that comprises end piece and be hinged with end piece, described mirror bar comprises interconnective straight bar section and deformation section.Deformation section comprise connect successively adapter, the first elastomer block, the second elastomer block and spacing section.When deformation section is squeezed, can outwards arch upward, the first elastomer block and the second elastomer block serve the effect of support, increase the elastic recovery capability of deformation section.Adapter, the first noumenon groove is offered respectively in first elastomer block and the second elastomer block, second body groove and the 3rd body groove, the first stopper slot is provided with between described adapter and the first elastomer block, the second stopper slot is provided with between described first elastomer block and the second elastomer block, the 3rd spacing half groove is provided with between described second elastomer block and spacing section, due to the first noumenon groove, second body groove and the 3rd body groove and the first stopper slot, it is contrary that the notch of the second stopper slot and the 3rd stopper slot offers direction, when the first noumenon groove, when second body groove and the 3rd body groove direction are squeezed, first stopper slot, second stopper slot and the 3rd stopper slot can produce corresponding reacting force, ensure that adapter, first elastomer block, the stability of the second elastic block structure.When the first stopper slot, the second stopper slot and the 3rd stopper slot direction are squeezed, the first noumenon groove, the second body groove and the 3rd body groove can produce the stability that corresponding reacting force ensure that adapter, the first elastomer block, the second elastic block structure, therefore do not take turns deformation section be subject to which direction external force extruding time, each body groove and each stopper slot all can ensure structural stability and the structural strength of deformation section, further increase the elastic recovery capability of deformation section.
Due to the first stopper slot, the second stopper slot and all T-shaped shape of the 3rd stopper slot, significantly reduce the weight of deformation section, so alleviate ear and the bridge of the nose load, and the transportation cost of the manufacturer alleviated further.
2. the T-shaped shape of the first noumenon groove, first groove and second groove is comprised bottom vallecular cavity in this first noumenon groove, when the groove depth of first groove and the groove depth ratio of second groove are 0.6-0.85, the structural strength of the internal force that the first noumenon groove produces and adapter and stabilizing effect the best.

Embodiment
As Fig. 1, shown in 2: a kind of earpiece, the mirror bar 2 comprising end piece 1 and be hinged with end piece 1, mirror bar 2 adopts titanium silk to make, described mirror bar 2 comprises interconnective straight bar section 21 and deformation section 22, described deformation section 22 comprises the adapter 3 connected successively, first elastomer block 4, second elastomer block 5 and spacing section 6, link on adapter 3 and adopt screw to be hinged between end piece 1, described adapter 3, the first noumenon groove 30 is offered respectively in first elastomer block 4 and the second elastomer block 5, second body groove 40 and the 3rd body groove 50, the first stopper slot 31 is provided with between described adapter 3 and the first elastomer block 4, the second stopper slot 41 is provided with between described first elastomer block 4 and the second elastomer block 5, the 3rd spacing half groove 51 is provided with between described second elastomer block 5 and spacing section 6, described the first noumenon groove 30, second body groove 40 and the 3rd body groove 50 and the first stopper slot 31, it is contrary that the notch of the second stopper slot 41 and the 3rd stopper slot offers direction, the T-shaped shape of described the first noumenon groove 30, first groove 301 and second groove 302 is comprised bottom vallecular cavity in this first noumenon groove 30, the groove depth of described first groove 301 and the groove depth ratio of second groove 302 are 0.6-0.85: if when the groove depth ratio of the groove depth of first groove 301 and second groove 302 is greater than 0.6-0.85, the groove depth of first groove 301 is excessive, the structural strength of adapter 3 is caused to reduce, in adapter 3 with end piece 1 relative motion, adapter 3 is easily damaged.
If when the groove depth ratio of the groove depth of first groove 301 and second groove 302 is less than 0.6-0.85, the degree of depth of second groove 302 is excessively dark, the cell wall thickness of second groove 302 is reduced, causing second groove 302 when being squeezed, easily rupturing.Described spacing section 6 is provided with limited step 61, and described straight bar section 21 is connected with limited step 61.
Further, the notch of described the first noumenon groove 30, second body groove 40 and the 3rd body groove 50 all takes the form of inclined plane, and the notch angle of inclination of each body groove is 18 °-20 °.The design of this angle of inclination can prevent foreign object from falling in each body groove, protects the cleanliness factor of each body groove.
First stopper slot 31, second stopper slot 41 and all T-shaped shape of the 3rd stopper slot.
The 3rd groove the 510, three groove 510 is provided with equal with the groove depth of second groove 302 bottom vallecular cavity in 3rd spacing half groove 51.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
