Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1～Fig. 8, the utility model comprises bottom 1, scroll-type rotating disk 2, electric wire keeper 3, rotor 4, gland 5, pcb board 6, button 7, button cover 8, loam cake 9, web-like spring 10, electric wire 11, screw 12, steel ball 13 etc.One side of rotor 4 is provided with guide pillar 14 and cavity 4-1; The opposite side of rotor 4 is provided with stepped guide pillar 15; The middle part of rotor 4 is provided with through hole 4-2.The wherein one side of scroll-type rotor 2 is provided with steel ball positioning pit 16 and steel ball guiding gutter 17.

Bottom 1 is provided with positioning ball guiding gutter and axis 1-1, and positioning ball guiding gutter wherein is corresponding with steel ball guiding gutter 17 on the scroll-type rotating disk 2.Web-like spring 10 is hidden in the cavity 4-1 of rotor 4.Scroll-type rotating disk 2 is sleeved on the axis 1-1 of bottom 1, and is embedded on the rotor 4 by guide pillar 14.Electric wire about 11 minutes two the volume twist in respectively on the rotor 4, screw 12 is fixed on gland 5 on the axis 1-1 of bottom 1, compresses rotor 4, and can control the axial dipole field of rotor 4.Pcb board 6 and button cover 8 connect respectively and are fixed on the stepped guide pillar 15 of rotor 4, and button cover 8 can drive button 7, constitute button 7, button cover 8, pcb board 6 and rotor 4 and rotate simultaneously on same axle.Twist in electric wire 11 on the rotor 4 and pass through hole 4-2 and pcb board 6 welding on the rotor 4; And the other end of electric wire 11 connects earphone 18 and plug 19 respectively, constitutes complete loop.When electric wire 11 when pulled, driving rotor 4 rotates, simultaneously with parts such as the coaxial scroll-type rotating disk 2 of rotor 4, web-like spring 10 and the button that is connected with rotor 4 guide pillars 15 overlap 8, pcb board 6, button 7 also rotate, the electric wire 11 that twists on the rotor 4 is drawn out.When electric wire 11 is moved the end to, by the elastic force of web-like spring 10, rotor 4 revolutions, positioning ball 13 sticks into the positioning pit 16 of scroll-type rotating disk 2, rotor 4 stalls.When slightly spurring rotor 4 once more, positioning ball 13 is jumped out positioning pit 16, and drives revolution by the elastic force of web-like spring 10, and electric wire 11 is regained.Steel ball 13 can pause during by positioning pit 16; But when rotor 4 quick rotation, steel ball 13 is fast by positioning pit 16, and rotor 4 can not pause; Reclaim fast or pull out.Electric wire keeper 3 is equipped with in two electric wire exits at bottom 1, and its effect is when assembling and setting, and the control electric wire is in the skew of telescopic location.
