[0008] Working principle and beneficial effects of the present invention:

[0009] 1. Working principle: When using the capacitive pen, insert one end of the charger into the charging interface, and then connect the charger to the power supply to charge the battery inside the pen shell. The charging interface is a Type-c interface, which can be used for most chargers on the market. After the battery is fully charged, unplug the charging cable and press the button to make the battery inside the pen shell power the control module. The control module can transmit the picture to the display screen. The user can connect to the corresponding electronic device according to the display information on the display screen. When the corresponding electronic device and the capacitive pen Bluetooth are successfully matched, the capacitive pen can be used normally.

[0010] 2. Beneficial effects:

[0011] (1) The capacitive pen can be charged through the charging port on the top of the top cover.

[0012] (2) When the capacitive pen is in use, pressing a button enables the battery inside the pen housing to power the control module, and the control module can transmit the image to the display screen. The user can connect the corresponding electronic device to the Bluetooth according to the information displayed on the display screen. This not only makes it more convenient to connect the capacitive pen to the electronic device, but also allows the user to quickly switch the device connected to the capacitive pen, thereby making the use of the capacitive pen more convenient;

[0013] (3) The insert block is fixed inside the pen case by a limit assembly. After contacting the limit assembly, the top cover and the insert block can be removed from the pen case. Then the staff can take out the battery and the control module from the inside of the pen case, which makes it convenient for people to inspect and repair the capacitive pen.

[0014] Preferably, the limit assembly includes a sliding cavity opened at the bottom of the top cover, and the sliding cavity is symmetrically arranged on the top cover, the sliding cavity extends to the inside of the plug block, the inside of the sliding cavity is fixedly connected with a sliding plate, one side of the sliding plate is fixedly connected with a spring, the other end of the spring is fixedly connected to the inner wall of the sliding cavity, the bottom of the sliding plate away from the spring is fixedly connected to the limit block, a limit groove matching the limit block is opened on the pen shell, the top of the sliding plate close to the limit block is fixedly connected with a button, one end of the button away from the sliding plate extends out of the top cover, and the button is slidably connected to the top cover, and the two buttons on the top cover are pressed at the same time.
