Self-rotating reset capacitance pen

The self-rotating reset capacitance pen comprises a pen tube and a rotating reset type pen tail mechanism, the pen tube is provided with a capacitance pen body mechanism, the capacitance pen body mechanism is used for completing man-machine interaction with a touch control capacitance type screen, and one end of the capacitance pen body mechanism is provided with a charging interface part and a function display part. The charging interface part is used for charging, the function display part is used for function display, the rotary reset type pen tail mechanism is coaxially arranged on the pen tube, and the charging interface part and the function display part are both arranged on the rotary reset type pen tail mechanism. And the rotary reset type pen tail mechanism is used for exposing the charging interface part for charging or exposing the function display part for function display. The charging socket has the advantages of being capable of effectively preventing water and dust and automatically resetting
