Simultaneously displaying the current liquid level value of the ink in real time through a display device; the ink can be added according to the current liquid level value; the problem that ink needs to be added frequently due to the fact that ink in the pen body is too little is avoided, and meanwhile the problem that writing is not smooth due to the fact that ink in the pen body is too much is also avoided.

The method comprises the following steps:

the step (10) is specifically as follows: pulling out the ink bottle; the ink bottle drives the detecting device to move upwards; because the lower pressing part is movable in the lower pressing groove; when the ink bottle drives the first pressing part to reach the top of the pressing groove; the lower pressing groove limits the first lower pressing part; continuously pulling out the ink bottle; the ink bottle is separated from the pressing part.
