A battery circuit 6 is embedded in the pen body 1. The main control chip of the battery circuit 6 is an IP5305, which can charge and discharge simultaneously. The battery circuit supplies power to the stylus. One end of the battery circuit 6 is electrically connected to the main control module 2 via a wire. The microcontroller of the main control module 2 is an ESP32C3Mini. The other end of the battery circuit 6 is electrically connected to a wire interface 11 via a wire. The other end of the wire interface 11 is electrically connected to a trackball 13 via a wire. When the trackball 13 is pressed, it is considered to be in contact, thereby enhancing the user's handwriting experience, facilitating the collection of handwriting, and not affecting the use.
[0037] A wireless coil transmitter module 22 is fixedly installed inside the wireless charging case 27, and the other end of the battery circuit 6 is electrically connected to a charging wire 8 via a wire. The other end of the charging wire 8 is electrically connected to a wireless coil receiver module 9 via a wire. The wireless coil receiver module 9 is located at the tail end of the pen barrel 1 and is set to correspond to the wireless coil transmitter module 22. A charging indicator port 15 is opened on the outer wall of the pen barrel 1 corresponding to the wireless coil receiver module 9. Therefore, the battery circuit 6 can be charged by the cooperation of the wireless coil transmitter module 22 and the wireless coil receiver module 9, so that the stylus can be wirelessly charged by placing the entire stylus in the wireless charging case without the need for a separate wired connection to an external device for charging, which improves the convenience of using the stylus.

[0041] An infrared emitter 20 is fixedly installed inside the pen tip 25, and a pen refill 21 is fixedly installed inside the pen tip 36. Whether infrared light overflows when the infrared emitter 20 contacts the plane determines whether contact has occurred. The pen refill 21 is a common carbon pen refill, and writing can be performed normally through the pen refill 21. An LED light 10 is set on the battery circuit 6, and an LED port 16 is opened on the outer wall of the pen barrel corresponding to the LED light 10. There are four LED lights 10.
