Abstract: A computer mouse with retractable cable is disclosed. The internal of the computer mouse contains coil spring, reeling disc, positioning bead and conductors. The lead wire once pulls, it is positioned and a second pull will restore back to its original position. The pulling of lead wire controls the required length of the mouse.

Abstract: A cable winding device includes a top cover mounted to a bottom cover to interpose therebetween a rotary cable winding hub that defines between top and bottom frames a circumferential slot for winding up a cable therein. The top frame forms a space receiving therein a roll-up spring that provides a biasing force to the cable winding hub for winding up the cable. The bottom frame forms a recess fit over a raised fixing base extending from the bottom cover and forming multiple tracks that have a stop end for cooperating a limiting groove defined in the fixing base to properly retain the cable winding hub for each turn of rotation of the cable winding hub in extending the cable.

Abstract: A power adaptor of the present invention has a single power cable connecting between an adaptor body and an electric device. The power cable can be conveniently retrieved or dispensed by a cable winder for easy management. The plug for plugging into a power source is directly installed on the adaptor body. The prongs of the plug is mounted on a sliding rail inside the adaptor body so that the prongs can be stuck out for plugging or completely retracted inside the adaptor body for transportation or storage. Conducting plates are provided along the sliding rail so that the prongs are always in reliable contact with the conducting plates for the conduction of electricity to the electric member inside the adaptor body. When the prongs are fully exposed or when the prongs are completely concealed, the prongs are securely locked to the adaptor body.

Abstract: The power adaptor contains a body assembly having an indentation for receiving and charging a re-chargeable battery pack. The body assembly also provides a standard USB socket into which a device can be plugged and charged. The charging to the battery pack and through the USB interface can be conducted at the same time. The power adaptor also contains one or more plug members, each having prongs of a specific style or specification. A plug member is detachably joined to the body assembly and, by installing an appropriate plug member, the power adaptor can be plugged into a wall socket of a specific style so as to draw electricity for the charging.
