BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an electrical power receptacle, in particular, to an electrical power receptacle with rotatable USB jacks. 
     2. Description of Related Art 
     With the present continuous development of modern society, more and more electronic devices are utilized in public. To operate the electronic devices, electrical power supplies are required to drive the electronic devices. Generally specking, peripheral electronic devices are usually designed as portable electronic devices. Because the main design factors for portable electronic devices emphasize on how to reduce an overall dimensional size or overall weight, it is not suitable to connect with the public electrical power distribution system for electrical power directly. Consequently, a conventional method for supplying electrical power to the conventional peripheral electronic devices is to utilize USB connectors which are capable of connecting to USB jacks of main electronic apparatuses electrically. 
     Yet, the above-mentioned USB connection for the portable electronic devices is an indirect connection by connecting to the USB jacks designed on the main electronic apparatuses for achieving the intended objectives of connecting the portable electronic devices electrically. Thus, the limitations of the USB interface connection, no only increase the burden for manufactures to redesign circuitry for the main electronic apparatuses with regards to the USB connection, but also increase the limitations in use. Because the old design for electronic apparatuses does not have USB jacks, these old apparatuses are not compatible with the present peripheral electronic devices by applying USB connectors. 
     Meanwhile, in response to the present requirements with the vigorous development of portable electronic devices, electronic device design is tended towards increasing portability for ease and convenience of movement. However, the conventional USB jacks are usually firmly installed on the peripheral area of the electronic apparatuses. Thus, as long as the USB connectors of the portable electronic devices connect to the aforementioned fixed USB jacks, the movement range of the portable electronic devices is restricted by the USB connection direction, the convenience of mobility is also reduced, and the USB connectors applied for portable electronic devices are vulnerable to be damaged due to improper operations, thereby reducing the service life thereof. 
     SUMMARY OF THE INVENTION 
     As per the aforementioned issues, a primary objective of the present invention is to provide an electrical power receptacle with rotatable USB Jacks in accordance with the structural design thereof for solving the restrictions in USB connection directions with regards to the conventional fixed type USB jacks. Furthermore, the design of USB jack assembly according to the present invention provides a simplified and direct electrical connection interface for a variety of electronic devices adapted for the USB interface connection. Moreover, the electrical power receptacle with rotatable USB jacks according to the present invention simplifies the structure design, thereby decreasing the overall manufacturing cost. 
     To solve the aforementioned issues, disclosed is an embodiment of an electrical power receptacle with rotatable USB jacks according to the present invention, comprising a main body, at least an electrical outlet assembly, a rotating member, and at least a USB jack assembly. Herein, the main body includes at least a shaft section; at least one electrical outlet assembly is disposed on the main body; the rotating member is mating engagement with the shaft section and is capable of rotating with respect to a predetermined axis of the shaft sections in any angle in accordance with the structural design thereof; and at least one USB jack assembly is disposed on the rotating member, such that as the rotating member rotates, substantially, the USB jack assembly rotates as well. 
     As per the aforementioned electrical power receptacle with rotatable USB jacks according to the present invention, the USB jack assembly with a simplified design and low manufacturing cost may electrically connect to USB connectors of the electronic devices directly, instead of indirectly connecting to an intermediate electronic apparatus first, thereby increasing the power efficiency and convenience of use. Moreover, the rotating member of the electrical power receptacle with rotatable USB jacks is capable of adjusting the direction of the USB jack assembly with respect to various application environments and situations. In other words, the rotating member can change the rotational directions so as to reduce the restrictions in application range and prevent from damaging the USB connector, so that the service life of the USB connector will not be shortened due to improper operations in practice.
