BACKGROUND 
     1. Technical Field 
     The exemplary disclosure relates to support stands for supporting electronic devices. 
     2. Description of Related Art 
     Some support stands are used to support electronic products so the electronic product can sit on a desk or other supporting surface to make it more comfortable for the users to view the displays. However, typical support stands have a complicated structure and can not steadily support the electronic product. 
     Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
     An embodiment of a support stand  100  is shown in  FIGS. 1 and 2 . The support stand  100  includes a base  10 , two support rods  20 , a positioning rod  30 , and a support board  40 . The support rods  20  are rotatably mounted to the base  10 . The support board  40  can be removably positioned above the base  10  by the cooperation of the support rods  20  and the positioning rod  30 . 
     The base  10  defines two spherical holes  12 , and each spherical hole  12  rotatably retains one of the support rods  20 . The base  10  further includes a mounting board  15 . The mounting board  15  defines a retaining hole  151  in one side thereof for retaining the positioning rod  30  on the base  10 . The mounting board  15  further includes a plurality of retaining pins  152  protruding from another side thereof opposite to the retaining hole  151 . The base  10  defines an equal number of retaining troughs  153  corresponding to the retaining pins  152 . Each retaining pin  152  is retained in one of the retaining troughs  153  to hold the mounting board  15  to the base  10 . Positions of the spherical holes  12  and the mounting piece  15  form corners of a triangle for better supporting the support board  40 . 
     The support rods  20  are made of rigid material. Each support rod  20  includes a ball joint  21  located at one end thereof and a first magnet  22  located at another end thereof. The ball joints  21  have the same shape and size as the spherical holes  12 . Each ball joint  21  is located (e.g. by snap-fit) in one of the spherical holes  12  to rotatably retain (e.g. by snap-fit) a corresponding support rod  20  on the base  10 . 
     Referring to  FIG. 3 , the positioning rod  30  is made of flexible material. The positioning rod  30  is flexible enough to be bent but stiff enough to maintain a position to which it is bent. The positioning rod  30  includes a connecting end  31 , a retaining end  32  opposite to the connecting end  31 , and a second magnet  33 . The second magnet  33  is pivotably mounted (e.g., screwed) on the connecting end  31 . The retaining end  32  is non-movably retained (e.g. friction fit) in the retaining hole  151  so the positioning rod  30  is retained on the base  10 . 
     The support board  40  includes a front surface  41 , latching blocks  42  and a back surface  43 . Each latching block  42  is substantially L-shaped when located at corners of the support board. However, two elongated latching blocks  42   a  may be used ( FIG. 4 ) on a support board  40   a , or latching blocks or a single latching rim  42   b  can completely or substantially surround a support board  40   b  ( FIG. 5 ). The latching blocks  42  cooperatively enclose a latching space  44  for latching an electronic device  200 . In this exemplary embodiment, each latching block  42  is located in one corner of the support board  40 . Each latching block  42  includes a protective pad  421  located on an inner side thereof. The pads  421  protect the electronic device  200  latched between the latching blocks  42  from damage. The back surface  43  includes two third magnets  431  and a fourth magnet  432 . The third magnets  431  attach the first magnets  22  thereby retaining the support board  40  on the support rods  20 . The fourth magnet  432  attaches the second magnet  33  thereby retaining the support board  40  on the positioning rod  30 . 
     In assembly, each ball joint  21  is mounted in one of the spherical holes  12  to rotatably mount the support rods  20  on the base  10 . The retaining pins  152  are retained in the retaining troughs  153  so the mounting board  15  is retained on the base  10 . The retaining end  32  of the positioning rod  30  is retained in the retaining hole  151  so the positioning rod  30  is mounted on the base  10 . The first magnets  22  attract the third magnets  431  thereby retaining the support board  40  on the support rods  20 . Because the ball joints  21  can rotate in the spherical holes  12  in any direction, and the support rods  20  are mounted to the base  10  by the engagement of the ball joints  21  in the spherical holes  12 , the support rods  20  can rotate relative to the base  10  in any direction to adjust angles between each support rod  20  and the base  10 . After the angles between each support rod and the base  10  are adjusted, the positioning rod  30  is bent until the second magnet  33  is attached to the fourth magnet  432 . Thus, the support board  40  is steadily positioned above the base  10  by the support rods  20  and the positioning rod  30 , and is ready to support and position the electronic device for more comfortable use. 
     It is to be understood that the third magnets  431  and the fourth magnet  432  can be omitted when the support board  40  is made of iron or steel. 
     It is to be understood, however, that even through numerous characteristics and advantages of the exemplary disclosure have been set forth in the foregoing description, together with details of the system and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
