Embodiment:

For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, the utility model provides a kind of USB universal charger, comprise usb data line 8 and charging inlet 11, wherein usb data line 8 is connected with USB joint 16, be provided with interface pin position 15 in the charging inlet 11, be connected with a pin position governor motion between the interface pin position 15 of described usb data line 8 and charging inlet 11.Wherein said pin position governor motion is by last face-piece 2, down drain pan 7 and the spinning roller 4, pcb board 5 and the Metal Contact sheet 6 that are installed between the two constitute, described spinning roller 4 and Metal Contact sheet 6 run through the both sides up and down of being fixed in pcb board 5 by axle 3, described pcb board 5 is fixed in the above by screw 9 in shell 2, the following drain pan 7, tow sides respectively are welded with a LED lamp 10 on this pcb board 5, described LED lamp 10 parts are separately fixed in face-piece 2, following drain pan 7 housings, and be electrically connected between Metal Contact sheet 6 and the pcb board 5, can drive Metal Contact sheet 6 and rotate by rotating spinning roller 4.

Be provided with circular hole 18 above the last face-piece 2, one week of the outside of this circular hole 18 promptly goes up face-piece 2 and is provided with reference mark, be fixed with spiral cover 1 in the circular hole 18, should go up spiral cover 1 bottom fixed card is connected on the axle 3, upper face is provided with cue mark 20, and this cue mark 20 is corresponding with the above-mentioned reference mark of going up on the face-piece 2.And also be provided with corresponding circle hole on the drain pan 7 under described, and being fixed with screwed lid 12 in the circular hole, this screwed lid 12 is provided with cue mark, is a through hole in the middle of the screwed lid 12, and screw 13 passes the lower end that this through hole is fixed on axle 3.

In addition, the both sides of last face-piece 2 are provided with opening 17, spinning roller 4 then is arranged in this opening 17, and the dual-side of spinning roller 4 protrudes from this opening 17, by rotating this projection, spinning roller 4 is rotated, and drive its lower end Metal Contact sheet 6 and rotate, drive simultaneously and go up spiral cover 2 and screwed lid 12 corresponding rotations, and by the current position of cue mark 20 indications, the interface pin position 15 that this position is contacted with Metal Contact sheet 6 in correspondence with each other.
