That is, when the gravity sensor detects the change of the position of the pen body, the Hall switch can be triggered to change the on and off states of the capacitive pen.

Specifically, as shown in FIG. 5 , a pen cap is connected to the tail of the pen body, and a pen cap iron 31 is connected to the inside of the pen cap. Due to the lightness of the pen, the cap iron acts as a counterweight. The lower end of the cap iron piece is the wireless charging coil 32 , and the wireless charging coil is finally connected to the battery 82 .

Further, in one embodiment, as shown in FIG. 6 , the cap can be connected to a power supply module (not shown in the figure) of the capacitive pen through the spring 4 and used to switch the capacitive pen on and off. That is, the capacitive pen can be turned on and off by pressing down on the cap. Preferably, as shown in FIG. 7 , the spring can be a tail spring including a tail pin 41 , with a wire diameter of 0.3 and a pitch of 1.2-1.5 mm; that is, the tail pin contacts the power module of the capacitive pen.
