The present invention relates to the technical field of digital terminals, and provides a rotation-type touchscreen operating device, used to operate a digital terminal having a touchscreen. The rotation-type touchscreen operating device comprises a main body being capable of holding the digital terminal, and rotatably provided with an operating arm. An end of the operating arm is provided with a touch portion used to press against the touchscreen. The operating arm rotatably provided on the main body can rotate in a plane parallel to the screen, and then the touch portion provided at the end thereof can operate the screen. In this way, when it is inconvenient for a user to operate a touchscreen directly with a hand, the present invention enables touch operations by means of operating the operating arm instead of using a finger, such that a touch digital device can meet user demand in various kinds of specific scenarios.
