[0002] In the field of electronic devices, especially in scenarios involving touch input devices, capacitive pens are widely used as key auxiliary tools. However, the current capacitive stylus designs on the market still have some shortcomings, including the following aspects:

[0003] 1. Weak battery life: Due to the size limitation of existing capacitive pens, the built-in battery capacity is usually small, which limits the working time of the capacitive pens;

[0004] 2. Low space utilization: The design of existing capacitive styluses fails to effectively optimize the internal space, and the layout of the components does not fully utilize the available space, resulting in limited space occupied by the battery and the inability to increase the battery volume to improve capacity;

[0005] 3. Excessive power consumption: Existing capacitive pens consume a lot of power during operation, which causes the battery to be consumed quickly, thus shortening the actual use time of the capacitive stylus.

[0006] Therefore, there is an urgent need for a capacitive stylus structure with long battery life. Utility Model Content
