The present invention relates to the technical field of digital terminals, and provides a retractable wind-up touchscreen operating device, used to operate a digital terminal having a touchscreen. The retractable wind-up touchscreen operating device comprises a main body being capable of holding the digital terminal. The main body is provided with an operating arm having an end elastically pressing against the touchscreen. An end of the operating arm is provided with a retractable elastic retraction portion. The main body is provided with a rotating structure used to reel the elastic retraction portion to retract or extend the operating arm. The main body is further provided with a position-restricting portion used to restrict the shape of the elastic retraction portion. The main body of the retractable wind-up touchscreen operating device can hold unto a digital terminal. The rotating structure of the main body can drive reeling of the elastic retraction to retract or extend, thus changing the length of the operating arm, and causing the operating arm to slide on the screen to operate the touch screen.
