     DESCRIPTION OF THE PRIOR ART 
     A smart mobile phone (using an Android system) has a function of transmitting videos and contents to a displaying device to be displayed thereby. However, such as function can only be performed by using a mobile high-definition link. Consequently, what is currently now available in the market is a device that can only be connected when an external power supply is available; otherwise it cannot be operated where no external power supply is available. 
     Overcoming such a problem is a major issue of the industry and is a goal that the present invention aims to achieve. 
     SUMMARY OF THE INVENTION 
     In view of the above problem and drawback, the present invention aims to provide a mobile high-definition link with built-in power supply that features a power-saving function of automatic detection and activation/deactivation a battery power source so that seeking for an external power supply is not necessary 
     The primary object of the present invention is to provide a solution that overcomes the problem that a conventional mobile high-definition link may not be operated due to it being hard to find an external power supply by providing a power-saving function of automatic detection and activation/deactivation a battery power source so that seeking for an external power supply is not necessary. 
     To achieve the above object, the present invention provides a mobile high-definition link with built-in power supply, which comprises: an adaptor module, a power supply module, and a battery. The power supply module is contained in the adaptor module and is electrically connected to an external power source. The adaptor module contains therein the battery, and the battery is electrically connected to the power supply module. The power supply module is automatically or manually switchable. The adaptor module comprises a transfer unit, which transfers a signal from a mobile device to a displaying device. The transfer unit is in information communication with the power supply module. The transfer unit forms a first interface with respect to the mobile device and also forms a second interface with respect to the displaying device, wherein the mobile device can be a smart mobile phone or a tablet computer and the displaying device can be a television set or a projector. The first interface and the second interface are in information communication with a detection module, which is in information communication with the power supply module. With the above arrangement, the power supply module is automatically or manually switchable to the external power source or the battery. When the transfer unit is to transfer a signal from the smart mobile phone or tablet computer to the displaying device, the adaptor module is automatically activated and uses the electrical power supplied from the power supply module to thereby realizes a power saving function of automatic detection and activation/deactivation of the battery power source and also provide an advantage of requiring no seeking for an external power supply.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims. 
     Referring to  FIGS. 1 ,  2 , and  3 , which are respectively a perspective showing an application of the present invention and a perspective view and a block diagram of the present invention, these drawings clearly show that the present invention provides a mobile high-definition link with built-in power supply, which comprises: an adaptor module  1 , a power supply module  10 , and a battery  101 . The power supply module  10  is arranged inside the adaptor module  1  and the power supply module  10  is electrically connected to an external power source  4 . The adaptor module  1  contains the battery  101  therein. The battery  101  is electrically connected to the power supply module  10 . The power supply module  10  is automatically or manually switchable between the external power source  4  and the battery  101 . The adaptor module  1  contains therein a transfer unit  12  and the transfer unit  12  transfers a signal from a mobile device  2  to a displaying device  3 . A first interface  13  is formed between the transfer unit  12  and the mobile device  2  and a second interface  14  is formed between the transfer unit  12  and the displaying device  3 . The transfer unit  12  is in information communication with the power supply module  10 . The mobile device  2  can be a smart mobile phone or a tablet computer, and the displaying device  3  can e a television set or a projector. The first interface  13  and/or the second interface  14  is in information communication with a detection module  11 , and the detection module  11  is in information communication with the power supply module  10 . 
     With the above arrangement, the operation of the present invention will be described, reference being had to  FIGS. 1 ,  3 ,  4 ,  5 , and  6 , which are respectively a perspective showing an application of the present invention, a block diagram of the present invention, and perspective views showing the present invention being operated with the battery, the present invention being operated with an external power supply, and the present invention carrying out a charging operation, the drawings clearly show that when the transfer unit  12  receives a signal indicating the mobile device  2  (a smart mobile phone or a tablet computer being taken as an example but not limited thereto) or the displaying device  3  (a television set or a projector being taken as an example but not limited thereto) connecting to the first interface  13  or the second interface  14 , the detection module  11  automatically activates the transfer unit  12  to use the electrical power supplied from the power supply module  10  in order to save the power of the battery  101 . Further, when the power supply module  10  is not yet set in electrical connection with the external power source  4 , supply of electrical power from the battery  101  will be effected so that there is no need to hurry to find an external power source  4 . When the power supply module  10  is in electrical connection with the external power source  4 , automatic switching of the power supply module  10  or manual switching may be done to switch to the external power source  4  or the battery  101 . (Here, automatic switching of the power supply module  10  is taken as an example for illustration.) When connection to the external power source  4  is not yet established, the power supply module  10  receives electrical power from the battery  101  in priority and when connection to the external power source  4  is made, the power supply module  10  receives electrical power from the external power source  4  in priority and charges the battery  101  simultaneously. When signal connection to the displaying device  3  or the mobile device  2  is broken, the external power source  4  may still maintain the charging operation to the battery  101 . Thus, advantages of easy use and saving power of the battery  101  can both be realized.
