     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to  FIG. 1  and  FIG. 2 , it shows three-dimensional schematic views of a cell phone docking charger of the present invention. As shown in the drawings, the cell phone docking charger  00  of the present invention comprises a charging unit  10 , a 2-pin AC plug  20 , a rotary disk  30  and a recharge connector  40 . 
     Referring to  FIG. 3  at a same time, it shows a three-dimensional exploded view of the cell phone docking charger of the present invention, wherein the charging unit  10  is the core of the charger and is used to emplace all kinds of electronic elements. The charging unit  10  is provided with the rotary disk  30 , a fixing groove  11  for containing the rotary disk  30 , and the recharge connector  40 , as well as a containing slot  12  and two shaft holes  13  of the recharge connector  40 . The shaft holes  13  are tightly sheathed with pivots  41  that are provided on the recharge connector  40 , allowing the recharge connector  40  to rotate by various angles. 
     The AC plug  20  is the input end of the charger and two sides of the AC plug  20  are provided with a pivot  21  respectively. The pivots  21  are sheathed with shaft holes  32  that are provided on the rotary disk  30 , so that the rotary disk  30  can be rotated for containing, thereby reducing the size of the charger to facilitate carrying. 
     The rotary disk  30  is provided at a side of the charging unit  10  to emplace the AC plug  20  and the angle of the AC plug  20  can be adjusted according to the orientations of holes of the wall receptacle. The rotary disk  30  is provided with a containing slot  31  to contain the AC plug  20 , and two sides of the containing slot  31  are provided with a shaft hole  32  respectively. The shaft holes  32  are sheathed with the pivots  21  that are provided on the AC plug  20 , enabling the AC plug  20  to rotate for containing. 
     The recharge connector  40  is the output end of the charger, and two sides of the recharge connector  40  are provided with the pivot  41 , respectively. The pivots  41  are sheathed with the shaft holes  13  that are provided on the charging unit  10 , so that the recharge connector  40  can be opened and closed by rotation and can be used to connect to a cell phone for recharging. In addition, the recharge connector  40  can be adjusted to plural angles according to the length or width of the cell phone. 
     Referring to  FIG. 4  and  FIG. 5 , it shows three-dimensional schematic views of the cell phone docking charger  00  of the present invention, with that the AC plug  20  rotates bi-directionally, e.g. left and right by 90 degrees. 
     Referring to  FIG. 6 , it shows a three-dimensional schematic view of another embodiment of the recharge connector of the cell phone docking charger, according to the present invention. As shown in the drawing, the recharge connector  40  can be further a Mini USB (Universal Serial Bus) or a Micro USB connector that is often used as the recharge connector of the cell phone. 
     Referring to  FIG. 7 , it shows a schematic view of the present invention that is used to recharge a short cell phone A, wherein the recharge connector  40  is adjusted to a proper angle, enabling the short cell phone A to be leaned against on a wall for recharging. 
     Referring to  FIG. 8 , it shows a schematic view of the present invention that is used to recharge a medium-long cell phone B, wherein the recharge connector  40  is adjusted to a proper angle, enabling the medium-long cell phone B to be leaned against on a wall for recharging. 
     It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
