Referring to fig. 1, for the first embodiment of the present invention, this embodiment includes conductive part 1, triode 2, first resistor 31, second resistor 32, first power source 41, second power source 42 and first diode 51, triode 2 in this embodiment is an NPN type triode, wherein triode 2 includes collector 21, base 22 and emitter 23, collector 21 of triode 2 is electrically connected with conductive part 1 through first diode 51, collector 21 is electrically connected with first power source 41 simultaneously, base 22 is electrically connected with second power source 42, emitter 23 ground connection is handled. In this embodiment, in order to protect the circuit component, the collector 21 is electrically connected to the first power interface 41 through the first resistor 31, the base 22 is electrically connected to the second power interface 42 through the second resistor 32, the cathode of the first diode 51 is electrically connected to the conductive part 1, and the anode is electrically connected to the collector 21 of the transistor 2. In an operating state, the conductive part 1 is placed on the screen of the intelligent terminal, the first power interface 41 is connected to a voltage signal of 5V, and the second power interface 42 is connected to a pulse voltage signal. Because the first power interface 41 is connected with a high potential and the second power interface 42 is a low potential signal (such as 0.3V), the first diode 51 is conducted, the conductive part 1 is electrified, and a coupling capacitor is generated between the conductive part 1 and the intelligent terminal screen, so that the effect of touching the screen is achieved; when the second power interface 42 is a high-potential signal (e.g. 3V), the potential of the base 22 is higher than that of the emitter 23, so that the transistor 2 is turned on to realize shunting, the voltage of the conducting part 1 suddenly drops, and the coupling capacitance generated between the intelligent terminal and the screen cannot be detected by the intelligent terminal, so that the effect of touching the screen by a point cannot be realized, and thus the effect of repeatedly touching the screen by a hand and separating the screen from the hand can be simulated by inputting a pulse signal to the second power interface 42, and the frequency of the pulse signal is the frequency of clicking.

In an operating state, the conductive part 1 is firstly placed on the screen of the intelligent terminal, the first power interface 41 is connected with a voltage signal of 5V, and the second power interface 42 is connected with a pulse voltage signal. Since the first power interface 41 is connected to a high potential and the second power interface 42 is a low potential signal (e.g. 0.3V), the transistor 2 cannot be conducted, and thus the conductive part 1 cannot be powered; when the second power interface 42 is a high potential signal (e.g. 3V), the potential of the base 22 is higher than that of the emitter 23, so that the transistor 2 is turned on, and then the current of the first power interface 41 flows to the ground (grounding processing of the emitter 23), and meanwhile, since the screen of the smart terminal tends to have a weak potential, and since the conductive part 1 is in contact with the screen and has a common potential, the conductive part 1 also has a weak potential, then the first diode 51 can be turned on, and then the current flows to the ground (grounding processing of the emitter 23).
