BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to supporting assemblies, more particularly, to a supporting assembly for supporting an electronic device. 
         [0003]    2. Description of Related Art 
         [0004]    Electronic devices such as monitors and tablet computers may be supported by supporting assemblies to stand on a desk for conveniently showing contents therein. However, the supporting assemblies of related art usually have complex structures and may require many components to assemble.

     DETAILED DESCRIPTION 
       [0011]    The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
         [0012]    Referring to  FIGS. 1 and 2 , a supporting assembly in accordance with an embodiment, is used to support an electronic device  70 . The supporting assembly includes a mounting piece  10 , a stand  20 , a cover  30  and two pivot assemblies  50 . In one embodiment, the electronic device  70  is a monitor. 
         [0013]    The mounting piece  10  is generally square. Each of four corners of the mounting piece  10  defines a first mounting hole  19 . A pair of connection pieces  11  are uprightly located on the mounting piece  10 . Each of the pair of connection pieces  11  includes a first side  117  and a second side  116 . The two second sides  116  face each other. A guiding piece  112  is perpendicularly connected to a top edge of each of the pair of connection pieces  11 . The guiding piece  112  extends from the first side  117  of each of the pair of connection pieces  11 . Each of the pair of connection pieces  11  defines a pivot hole  113 . 
         [0014]    Each of the two pivot assemblies  50  includes a fastener  51 , two gaskets  52 , and a friction piece  53 . The fastener  51  defines a fixing hole  511 . Outside of the friction piece  53  is rough for generating friction force. A center portion of the friction piece  53  defines a double-D shaped first through hole  531 . A recess  534  is defined in a peripheral portion of the friction piece  53 . Each side of the recess  534  forms a barrier side  545 . Each of the two gaskets  52  defines a double-D shaped second through hole  521 . 
         [0015]    The stand  20  is formed by a bent rod. The stand  20  includes a base  21 . A skidproof pad  211  is set around the stand  20 . Opposite ends of the base  21  extend obliquely to form a pair of supporting arms  23 . Free ends of the pair of supporting arms  23  extend towards each other to form a pair of shafts  25 . The pair of shafts  25  are parallel to the base  21 . A distal end of each of the pair of shafts  25  is a fixing portion  251 . A cross section of the fixing portion  251  is double-D shaped corresponding to the first through hole  531  and second through hole  521 . A plurality of screw threads is formed on the fixing portion  251 . 
         [0016]    Each of four corners of the cover  30  defines a second mounting hole  31 . A central portion of the cover  30  is protruded to form a receiving portion  34 . A receiving space  341  is defined in the receiving portion  34 . 
         [0017]    The electronic device  70  includes a rear plate  71 . The rear plate  71  defines four third mounting holes  73 . 
         [0018]    Referring to  FIGS. 1 to 4 , in assembly, each of the two gaskets  52  is placed on the second side  116  of each of the pair of connection pieces  11 . The second through hole  521  is aligned to the pivot hole  113 . The friction piece  53  is placed on the first side  117  of each of the pair of connection pieces  11 . The first through hole  531  is aligned to the pivot hole  113 . The guiding piece  112  is received in the recess  534 . 
         [0019]    Then, the fixing portion  251  of each of the pair of shafts  25  is in turn inserted in the first through hole  531 , the pivot hole  113 , and the second through hole  521 . The fixing portion  251  is then fixed in the fixing hole  511  of the fastener to mount each of the two pivot assemblies  50  and the stand  20  on the mounting piece  10 . Each of the two gaskets  52  is firmly pressed against the second side  116 . The friction piece  53  is firmly pressed against the first side  117 . Because shaped of the first through hole  531 , the second through hole  521 , and the cross section of the fixing portion  251  are double-D shape, the two gaskets  52  and the friction piece  53  can rotate together with the pair of shafts  25 . When the pair of shafts  25  rotate in the pivot hole  113 , the friction piece  53  is rotated relative to the first side  117 , and friction force locates the stand  20  in a fixed position at the end of any rotation. Further, the pair of shafts  25  rotate until a barrier side  535  abuts the guiding piece  112 . 
         [0020]    The pair of shafts  25  and the pair of connection pieces  11  are placed in the receiving space  341  of the cover  30 . The mounting piece  10  is placed on the rear plate  71  of the electronic device  70 . The first mounting holes  19  and the second mounting holes  31  are aligned to the third mounting holes  73 . A plurality of screws is secured in the first mounting holes  19 , the second mounting holes  31 , and the third mounting holes  73 . So, the supporting assembly is pivotally mounted on the electronic device  70 . 
         [0021]    In use, the base  21  of the stand  20  is located on a desk. The skidproof pad  211  can prevent the base  21  from sliding. The pair of shafts  25  can rotate relative to the electronic device  70  to adjust a viewing angle of the electronic device. Friction force between the friction piece  53  and the first side  117  holds the electronic device  70  in different inclined positions. Further, each of the barrier sides  535  abuts the guiding piece  112  to prevent over-rotation. 
         [0022]    In the embodiment, the first through hole  531  shape can be other shapes not based on a circle, as long as the fixing portion  251 , the two gaskets  52  and the friction piece  53  are forced to rotate together. 
         [0023]    It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
