RELATED APPLICATION 
     This application claims priority of Taiwanese Application No. 097211870, filed on Jul. 4, 2008. The certificate of the aforesaid patent application is hereby provided. 
     BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a memory card socket. 
     2. Description of Related Art 
     Some electronic devices have a socket to electrically connect to a memory card, and the user can use the memory card to store data. Because one socket usually fits one format of the memory card and different formats have different widths and heights, the user can&#39;t read the memory card when the format of the memory card is different from the user&#39;s socket. Thus, it is necessary to develop the socket which can fit many formats of the memory card. 
     SUMMARY 
     According to one embodiment of the present invention, a memory card socket includes a body, and the body has a space for a memory card. The memory card socket further includes a plurality of pins, and the pins are disposed in the space to electrically connect the memory card. The memory card socket further includes a first elastic member and a second elastic member. The two elastic members are respectively disposed on the body and extend into the space for holding the memory card. The memory card socket further includes a blocking member, and the blocking member is disposed on the first elastic member. When the first elastic member is not deformed, the blocking member can restrain the second elastic member from being deformed outwardly from the space.

     DETAILED DESCRIPTION 
     In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawings. 
       FIG. 1  is a three dimensional view of a memory card socket according to one embodiment of the present invention.  FIG. 2  is an exploded view of the memory card socket of  FIG. 1 . The memory card socket includes a body  20 , a plurality of pins  30 , a first elastic member  50 , a second elastic member  40 , and a blocking member  51 . The body  20  has a first space  21 , and the pins  30  are disposed in the first space  21 . The two elastic members  40 ,  50  are respectively disposed on the body  20  and extend into the first space  21 . The blocking member  51  is disposed on the first elastic member  50 . 
       FIG. 3  is a three dimensional view of the first elastic member and the second elastic member of  FIG. 2 , depicting the first elastic member is not deformed.  FIG. 4  is a three dimensional view of the first elastic member and the second elastic member of  FIG. 2 , depicting the first elastic member is deformed. When the first elastic member  50  is not deformed, the blocking member  51  can restrain the second elastic member  40  from being deformed outwardly from the first space  21 . When the first elastic member  50  is deformed and the blocking member  51  releases the second elastic member  40 , the second elastic member  40  can be deformed outwardly from the first space  21 . 
     When the first space  21  receives a memory card, the pins  30  electrically connects to the memory card, and the two elastic members  40 ,  50  hold the memory card in the first space  21 . 
       FIG. 5  is a front view of the memory card socket of  FIG. 1 , depicting a Memory Stick Duo (MS Duo) memory card is inserted into the first space. When an MS Duo memory card  12  is inserted into the first space  21 , the second elastic member  40  presses the MS Duo memory card  12 , and the blocking member  51  restrains the second elastic member  40  from being deformed outwardly from the first space  21 . Thus, the first elastic member  50  and the second elastic member  40  can hold the MS Duo memory card  12  in the first space  21 . 
       FIG. 6  is a front view of the memory card socket of  FIG. 1 , depicting a Memory Stick (MS) memory card is inserted into the first space. When an MS memory card  11  is inserted into the first space  21 , the MS memory card  11  deforms the first elastic member  50 , and the blocking member  51  releases the second elastic member  40 . Therefore, the second elastic member  40  can be pressed by the MS memory card  11  and deformed outwardly from the first space  21 , and the first elastic member  50  and the second elastic member  40  can hold the MS memory card  11  in the first space  21 . 
     The body  20  has a second space  22 , and the second space  22  overlaps the first space  21 .  FIG. 7  is a front view of the memory card socket of  FIG. 1 , depicting a Multimedia Card (MMC) or Secure Digital (SD) memory card is inserted into the second space. When an MMC or SD memory card  13  is inserted into the second space  22 , the SD memory card  13  deforms the first elastic member  50 , and the blocking member  51  releases the second elastic member  40 . Therefore, the second elastic member  40  can be pressed and deformed outwardly from the second space  22 , and the first elastic member  50  and the second elastic member  40  can hold the SD memory card  13  in the second space  22 . 
     In the foregoing description, the first space  21  is adapted to some memory card formats such as MS and MS Duo, and the second space  22  is adapted to receive some memory card formats such as SD and MMC. In addition, the second elastic member  40  extends into the overlap of the first space  21  and the second space  22 . Moreover, the first elastic member  50  has a first extending part  52  and a second extending part  53 . The first extending part  52  extends into the first space  21 , and the second extending part  53  extends into the second space  22 . Thus, an MS memory card  11  can press the first extending part  52  to deform the first elastic member  50 , and an MMC or SD memory card  13  can press the second extending part  53  to deform the first elastic member  50 . 
     The first elastic member  50  is disposed on the top wall  60  of the body  20 , and the first elastic member  50  is made out of the same metal piece of the top wall  60 . The second elastic member  40  is disposed on the side wall  80  of the body  20 . Moreover,  FIG. 8  is a three dimensional view of the first elastic member  50  and the second elastic member  40  of  FIG. 2 , depicting the first elastic member  50  is disposed on the side wall  80  of the body  20  and the second elastic member  40  is disposed on the top wall  60  of the body  20 . And the second elastic member  40  is made out of the same metal piece of the top wall  60 . Therefore the blocking member  51  can block the second elastic member  40  from being deformed horizontally. 
       FIG. 9  is a three dimensional view of the memory card socket, depicting the first elastic member  50  is disposed on the bottom wall  90  of the body  20  and the second elastic member  40  is disposed on the side wall  80  of the body  20 .  FIG. 10  is a three dimensional view of the first elastic member  50  and the second elastic member  40  of  FIG. 9 , depicting the first elastic member  50  is disposed on the bottom wall  90  of the body  20  and the second elastic member  40  is disposed on the side wall  80  of the body  20 .  FIG. 11  is a three dimensional view of the first elastic member  50  and the second elastic member  40  of  FIG. 9 , depicting the first elastic member  50  is disposed on the side wall  80  of the body  20  and the second elastic member  40  is disposed on the bottom wall  90  of the body  20 . Therefore the blocking member  51  can block the second elastic member  40  from being deformed vertically. 
     The body  20  disposes the assistant elastic member  70 , and the assistant elastic member  70  extends into the first space  21  and the second space  22 . Moreover, the assistant elastic member  70  is opposite to the second elastic member  40 , thus the assistant elastic member  70  and the second elastic member  40  can clip and hold the memory card. 
     It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims.
