The utility model patent can effectively improve the portability of the mouse during use by adopting a clever structure and circuit design. The design is provided by setting a touch screen. When the user touches the touch screen and the thumb slides on the touch screen, the touch screen generates a corresponding electrical signal and transmits the signal to the single chip microcomputer, and the single chip processes the signal and transmits the signal to the wireless transmitter. In this way, the signal is emitted, and the combination of the left mouse button and the right mouse button and the touch screen during use can further shorten the wearer's work interruption time and improve the wearer's work efficiency.
