In another embodiment, the first connector plug  250  and the second connector plug  254  may be the same type of connector plug. 
     The housing  21  includes a rectangular top wall  211 , four side walls  213  perpendicularly extending from the four edges of the top wall  211 , and a cavity  210  defined by the top wall  211  and the side walls  213  for receiving the winding mechanism  23 . One of the side walls  213  defines a first gap  218 . 
     The external surface of the top wall  211  defines a long and narrow inserting recess  210  for receiving and electrically connecting the electronic device  1 . The inserting recess  210  extends the width of the top wall  211 . The top wall  211  presents a support board  2101 , protruding from the external surface of the top wall  211 , for supporting the electronic device  1 . The support board  2101  rises out of the inserting recess  210 , and includes an inclined surface (not labeled) facing the recess  210 . The inclined surface is inclined away from the recess  210 . 
     The underside of the top wall  211  presents a convex stage  212 , a pivot  214 , and four supporting legs  216 . The convex stage  212 , the pivot  214 , and the four supporting legs  216  all protrude from the inner surface of the top wall  211 . The four support legs  216  are at the four corners of the top wall to support the housing  21 . The convex stage  212  and the pivot  214  together enable the winding mechanism  23  to be mounted to the housing  21 . 
     The convex stage  212  defines an opening  2121  and a grasping notch  2123 . The opening  2121  is in the central section of the convex stage  212  and communicates with the inserting recess  210 . The opening  2121  allows the first connector plug  250  to pass through the top wall  211  to couple to the connector slot of the electronic device  1 . The grasping notch  2123  is attached on one side of the convex stage  212 . The pivot  214  locates on one side of the convex stage  212 , and faces the grasping notch  2123 . 
     The winding mechanism  23  includes a winding member  230 , a locking member  232 , and a driving member  234 . One end of the winding member  230  pivots on the pivot  214 , the other end of the winding member  230  is attached on the convex stage  212 . The driving member  234  is mounted to the winding member  230  and the housing  21  to drive the winding member  230  to rotate and carry the transmitting wire  252  with it. The locking member  232  is mounted to the winding member  230  and the housing  21  to lock the winding member  230  to the housing  21 . 
     Referring to  FIG. 4  also, the winding member  230  further defines a hollow space  2314  and a groove  2305  and presents a pivot part  2306 , a receiving part  2310 , and a partition board  2312 . The pivot part  2306  protrudes from the bottom of the winding member  230  and is located on one end of the winding member  230 . The pivot part  2306  is in a shape of a column and defines a pivot hole  2307 . The pivot part  2306  pivots on the pivot  214  via the pivot hole  2307 , the height of the pivot part  2306  is higher than that of the convex stage  212  in the longitudinal direction of the housing  21 , thus the winding member  230  is capable of rotating relative to the housing  21 . The receiving part  2310  extends from the pivot part  230  toward the top of the winding member  230 , and the receiving part  2310  is placed in a hollow space  2314  and a receiving space  2303  is formed by the receiving part  2310 . The receiving part  2310  defines a plurality of second gaps  2302  communicating with the receiving space  2303  and the hollow space  2314 . 
     The partition board  2312  is located in the hollow space  2314  and divides the hollow space  2314  into a first receiving groove  2301  and a second receiving groove  2309 . Two fastening elements  2308  perpendicularly protrude from the partition board  2312  towards the receiving part  2310 , and are received in the second receiving groove  2309 . The first receiving groove  2301  is in alignment with the opening  2121  of the housing  21 , and is capable of receiving the first connector plug  250 . The second receiving groove  2309  is capable of receiving the second connector plug  252 . The groove  2305 , which goes all the way around the winding member  230 , functions as a reel or spool for receiving the transmitting wire  252  when the transmitting wire  252  is wound by the winding member  230 . 
     The winding member  230  further sets a fixed shaft  2304 . The fixed shaft  2304  protrudes from the pivot part  2306  and is in the receiving space  2303 . 
     The locking member  232  includes a first basic board  2320  and a second basic board  2322  protruding from the first basic board  2320 . The first basic board  2320  presents two cylindrical sleeves  2325  and a buckling part  2323  protruding from the second basic board  2302 . The sleeves  2325  are sleeved on the fastening elements  2308  of the winding member  230  and may slide along the fastening elements  2308 . The buckling part  2323  is away from the second basic board  2322  and is inserted into the grasping notch  2123  of the housing  21 . The second basic board  2322  covers above the first receiving groove, and defines a locking notch  2321 . 
     The driving member  234  is received in the receiving space  2303 . The driving member  234  is an elastomer, and is wound clockwise to form a coil. The two opposite ends of the driving member  234  are bent into small cylinders. The end of the driving member  234  in the center of the coil is secured to the pivot  214  of the housing  21  via a screw  2310 . The other outer end of the driving member  234  is secured on the fixed shaft  2304 . 
     To assemble the base  2 , the first connector plug  250  is passed through the first receiving groove  2301  of the winding mechanism  23  and the opening  2121  of the housing  21  so that the first connector plug  250  extends outside the housing  21 . The locking member  232  is slid to the partition board  2312  along the fastening elements  2308  to lock the first connector plug  250  and the transmitting wire  252  in the locking notch  2321  and the buckling part  2323  is clasped in the grasping notch  2123 . At this time, the locking member  232  enables the winding member  230  to lock into the housing  21 . The transmitting wire  252  is wound around the winding member  230  and received in the groove  2305 . The second connector plug  254  is clasped between one of the fastening elements  2308  and the receiving part  2310 . As the data cable  250  is received in the housing  21  in this way, the assembly of the base  2  is finished. 
     When the data cable  25  is to be connected to another electronic device, the locking member  232  is slid away from the partition board  2312  to unclasp the buckling part  2323  from the grasping notch  2123 . The second connector plug  254  is pulled from the second receiving groove  2309  and the transmitting wire  254  may be unwound. At the same time, the first connector plug  250  is pulled out of the opening  2121  into the first receiving groove  2301  and the winding member  230  is unlocked. The winding member  230  is spun anti-clockwise by virtue of the tension in the driving member  234 . Even when the transmitting wire  252  has been fully drawn out, the winding member  230  is locked into the housing  21  again by the means described above. The transmitting wire  252  is passed through the first gap  2302  and through the second gap  218  to extend out of the housing  21 , and at this point, the second connector plug  254  is capable of being coupled to the other electronic device. 
     When the data cable  25  is not being used, and the second connector plug  254  is freed from another electronic device, the winding member  230  is unlocked from the housing  21  again by the means described above. The winding member  230  automatically rewinds to re-coil the transmitting wire  252  under elastic force. 
     As described above, in being supported by the base  2  instead of being held in the hand, the viewing of the electronic device  1  is easier and more convenient. Further, the automatic regathering and rewinding of the data cable  25  into the housing  21  of the base  2  avoids any carrying and storage difficulties concerning the data cable  25 . 
     It is to be understood, however, that even though relevant information and the advantages of the present embodiments have been set forth in the foregoing description, together with details of the functions of the present 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 present embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
