In actual use, when there is no mobile phone, computer or other external device connected, the switching module switches the signal of the second port (i.e. USB port signal) to the central processing unit (i.e. outputs the USB port signal to the CPU), thereby realizing the function of the computer all-in-one machine. At this time, the keyboard, mouse and other devices control the self-operation interface of the computer all-in-one machine. When there is an external device connected through the first port, the switching module switches the signal of the second port to the first connection unit (i.e. outputs the USB port signal to the port of the first connection unit), at this time, the mouse keyboard and other devices control the above-mentioned mobile phone, computer and other external devices. In summary, the present application sets the corresponding switching module, which is convenient for switching the signal of the second port to the central processing unit or the first connection unit, thereby realizing the function of the keyboard and mouse to selectively control the self-operation interface of the computer all-in-one machine or the mobile phone, tablet and other external devices, i.e. simply and quickly realizing the display function mode, automatic switching of keyboard and mouse control and sharing of external device functions.
