Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-3, a kind of embodiment that this utility model provides：Built-in can Trigger Function USB joint mobile eventually
End data connecting line, including USB joint 3, suspension ring 4, terminal fitting 7, data wire 9 and rotary shaft 17, data wire 9 is by universal hinge
11 are connected with USB joint 3 and terminal fitting 7, and universal hinge 11 is arranged on two ends, USB joint 3 and the terminal fitting 7 of data wire 9
Side be connected with USB joint protective cover 1 and terminal fitting protective cover 6 by rope yarn respectively, and USB joint 3 pass through retainer ring
