     Though a structure in the embodiment of  FIG. 4  or  FIG. 5 , the connection between the processing module and the input module and/or output module can be more flexible. 
     The touch control handle device of the present disclosure is used for touch control of a capacitive touch screen which includes a self-capacitive touch screen and a mutual-capacitive touch screen. Depending on different principles, the self-capacitive touch screen only allows single-touch while rite mutual-capacitive touch screen a Bows multi-touch. Therefore, the mutual-capacitive touch screen is most commonly used. 
     Will reference to  FIG. 6 , a structural schematic diagram of a specific implementation of an output module in a touch control handle device in an embodiment is shown. In the embodiment, the touch control handle device is applied to a mutual-capacitive touch screen which comprises a plurality of signal transmitting electrodes  601  and a plurality of signal receiving electrodes  602  arranged as a crisscross array, wherein touch points are formed at locations where the signal transmitting electrodes  601  and the signal receiving electrodes  602  overlap. 
     Capacitance is formed at the locations where the signal transmitting electrodes  601  intersect with and the signal receiving electrodes  602 , that is, the two sets of electrodes respectively form two poles of the capacitance. When the finger touches the capacitive touch screen, coupling between the signal transmitting electrodes  601  and the signal receiving electrodes  602  at one or more touch points is affected, thus changing the capacitance between the two sets of electrodes. 
     The touch location is apiece of two-dimensional information containing a horizontal coordinate (X) and a longitudinal coordinate (Y), wherein the X coordinate determines tire selection and the amplification times of various excitation signals, while the Y coordinate determines the location selection and amplification times of the output signal; when mutual capacitance is detected, the horizontal signal transmitting electrodes  601  send excitation signals in sequence, and the longitudinal signal receiving electrodes  602  receive the signals at the same time, so that capacitance values at the intersection points of the horizontal and longitudinal electrodes can be obtained, namely the capacitance of a two-dimensional plane of the entire touch screen. The coordinate of each touch point can be calculated according to the two-dimensional variation data of the capacitance of the touch screen. Therefore, even if a plurality of touch points are on the touch screen, the real coordinate of each touch point can be calculated. 
     The output module comprises a signal collection component  603 , a first signal output component  604  and a first processing component  605 . 
     The signal collection component  603  is used to be electrically coupled with the signal transmitting electrodes  601  of the capacitive touch screen to acquire the excitation signals, and comprises electrodes for realizing the electric coupling. 
     The first signal output component  604  is used to be electrically coupled with the signal receiving electrodes  602  of the capacitive touch screen to output analog touch signals, and comprises electrodes for realizing the electric coupling. 
     The list processing component  605  is communicatively connected to the signal collection component  603  and the first signal output component  604 , wherein the first processing component  605  is used for receiving a touch control command, the touch control command means to execute the touch operation on the location to be touched on the capacitive touch screen; the first processing component  605  is used for receiving the excitation signals of the signal receiving electrodes at the touch points at the location to be touched, generating the analog touch signals according to the excitation signals, and outputting the analog touch signals to the signal receiving electrodes  602  at the touch points at the location to be touched via the first signal output component  604 , so as to simulate the touch operation on the location to be touched. 
     The analog touch signals result from amplifying the excitation signals to cause capacitance value variation at the corresponding touch points, and simulate the effect of superposing capacitance variation at the time of finger touch, thus generating trigger operation. 
     For example, if the touch operation on a point A in an image needs to be triggered, the touch operation on the point A is implemented by acquiring an excitation signal from a signal transmitting electrode A1 where the point A is located, processing the excitation signal into an analog touch signal and sending the analog touch signal to the signal receiving electrode A2 where the point A is located. 
     Optionally, the signal collection component  603  or the first signal output component  604  can comprise a body made of a transparent material and electric lines in the body; the transparent material is (for example) glass, acrylic, etc., winch does not affect watching on the capacitive touch screen even when covering the surface of the capacitive touch screen; of course, the body may not be made of transparent material and is not limited thereto. 
     Optionally, the first processing component  605  can be integrated in the processing module to reduce the cost and the circuit complexity. 
     Will reference to  FIG. 7 , a structural schematic diagram of a specific implementation of an output module in a touch control handle device in another embodiment of the present disclosure is shown. 
     Different from the previous embodiment, the touch control handle device in the embodiment is applied to a self-capacitive touch screen. Different contents at the embodiments are introduced hereinafter, and technical details which can be commonly used between the embodiments are not described again. 
     The capacitive touch screen comprises a plurality of horizontal electrodes  701  and a plurality of longitudinal electrodes  702  arranged as a crisscrossed array and respectively forming capacitance with the ground, wherein touch points are formed at locations where the horizontal electrodes  701  and the longitudinal electrodes  702  overlap, and when the finger touches the capacitive touch screen, the capacitance on the finger is overlapped to the formed capacitance, increasing the capacitance. 
     In the embodiment, the touch control handle device comprises a second signal output component  703  and a second processing component  704 . 
     The second signal output component  703  is used to be electrically coupled with the horizontal electrodes  701  and the longitudinal electrodes  702  of the capacitive touch screen; and 
     the second processing component  704  is communicatively connected to the second signal output component  703 , wherein the second processing component  704  is used for receiving a touch control command, the touch control command means to execute the touch operation on a location to be touched on the capacitive touch screen; the second processing component  704  is used for generating a analog touch signal according to the touch control command, and outputting the analog touch signal to the horizontal electrodes  701  and the longitudinal electrodes  702  at the touch points at the location to be touched via the second signal output component  703 , so as to simulate the touch operation on the location to be touched. 
     Depending on the difference of the working principles of the self-capacitive touch screen and the mutual-capacitive touch screen, in the embodiment, when the touch operation is required to be performed on a certain location to be touched, only the ground capacitance of the horizontal electrodes  701  and the longitudinal electrodes  702  of the touch points at the location to be touched needs to be changed.

     In the above-mentioned embodiment, the signal collection component, the first signal output component and the second signal output component can at least partially cover the surface of the capacitive touch screen, it view of structure setting.

The touch control handle device of the present disclosure has a touch simulation mode completely different from the existing devices, responds sensitively and quickly, and promotes the user experience.
