Namely, when the gravity sensor detects the change of the pen body position, the Hall switch can be triggered to change the on-off state of the capacitance pen.

Specifically, as shown in fig. 5, the tail of the pen body is connected with a pen cap, and a pen cap iron piece 31 is connected in the pen cap. The pen cap iron piece can play a role of counterweight due to the lightness of the pen body. The lower end of the pen cap iron piece is provided with a wireless charging coil 32 which is finally connected with a battery 82.

Further, in an embodiment, as shown in fig. 6, the cap may be connected to a power module (not shown) of the capacitive pen through a spring 4 and used for switching the capacitive pen. That is, the capacitive pen can be turned on and off by pressing the pen cap. Preferably, as shown in fig. 7, the spring can be a tail supporting spring comprising a tail needle 41, the wire diameter of the tail supporting spring is 0.3, and the thread pitch of the tail supporting spring is 1.2-1.5 mm; namely, the power module of the capacitance pen is contacted through the tail needle.
