Please refer to FIG. 1B , which is a schematic diagram of a power adapter assembly in use according to a preferred embodiment of the present invention. When using the power adapter assembly, the user only needs to exert force on the plugs 102 and 104 to pull out the required length of the power cords 102a and 104a. Stores unused power cords inside the housing so long cords don't clutter up.

Please refer to FIG. 2 , which is an internal structure diagram of a power adapter assembly according to a preferred embodiment of the present invention. In order to further explain the structure and function of the power adapter assembly, the figure removes the upper case 101 . The power cord 102a is accommodated in the casing by being wound on the rollers 108a and 108b. The power cord 104a is accommodated in the casing by being wound on the roller 108c. The rollers 108b and 108c with gear teeth are coaxially fixed on the lower casing 103 . The rollers 108a, 108b and 108c are all driven by coil springs to wind the power cords thereon, and the rollers are prevented from rotating by the baffle 122 (when using the power adapter assembly). The baffle 122 is controlled by the button 106. When the user presses the button 106, the baffle 122 is separated from the rollers 108b and 108c, and the power cords 102a and 104a are received into the casing by the rotating rollers.

Please refer to FIG. 3 , which is an exploded perspective view of a power adapter assembly according to a preferred embodiment of the present invention, to explain the structure and function of the power adapter assembly more clearly. The casing of the power adapter assembly can be divided into an upper casing 101 and a lower casing 103 . The upper casing 101 has an opening 101a for the button 106 to be exposed outside the casing, and an opening 101b as a channel for the power cord 102a to enter and exit the casing. A groove 101c is designed on the upper casing 101 adjacent to the opening 101b to accommodate the plug 102 (when the storage is completed). The lower housing 103 has an opening 103a as a channel for the power cord 104a to enter and leave the housing. A groove 103b is designed on the lower housing 103 adjacent to the opening 103a to accommodate the plug 104 (when the storage is completed). The power cord 102a is accommodated in the casing by being wound on the rollers 108a and 108b. The coil spring 110a is fixed between the roller 108a and the rotating shaft 112a, so as to drive the roller 108a to wind the power cord 102a thereon. The rotating shaft 112a is fixed on the fixing structures 116a and 116b. The coil spring 110b is fixed between the roller 108b and the rotating shaft 112b, so as to drive the roller 108b to wind the power cord 102a thereon. The rotating shaft 112b is fixed on the fixing structures 118a and 118b. The power cord 104a is accommodated in the casing by being wound on the roller 108c.
