BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a 3C product, and more particularly to a 3C product with a data transmission wire accommodation structure. 
         [0003]    2. Description of the Prior Art 
         [0004]    When the existing portable 3C (Computers/Communications/Consumer) products  10 , such as mobile phone, digital camera, notebook, etc, are used to transmit data, as shown in  FIG. 1 , it requires a wire  11  with two terminals  112  at both ends thereof to be connected between the two 3C products  10 , and when charging a 3 product, it also needs to use a wire  11  with two terminals  112  at both ends thereof to connect the 3 product to be charged to the power source. 
         [0005]    Nowadays, most of people possess more than one 3C product  10 , and different 3C products  10  might have different types of ports  101 . For example, a digital camera and a mobile phone can&#39;t use a same wire  11  to perform data-transmission to a computer, and thus, the user has to prepare different wires  11  to fit different types of terminals  112 , which is not only inconvenient but also expensive. 
         [0006]    On the other hand, a wire body  111  of the wire  11  has a certain length and therefore is convenient for storage or to use. For example, it looks messy when the wire is plugged in a computer or power source, and it will cause dust accumulation and is inconvenient to carry when the wire is wound up. 
         [0007]    On top of that, since the wire is separated from the 3C product, the user is likely to forget the wire when on travel or out at work, and therefore has to buy a new wire when data transmission or power charging is needed. 
         [0008]    The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
