It can be understood that, when the range of the gap between the position-limiting flange 121 and the outer side of the pen point 32 is less than 0.05mm, due to the processing tolerance, when the pen point 32 extends out of the avoiding hole 10b, there is a situation of being stuck, so that the pen core 30 cannot be reset under the elastic force of the elastic element 40, thereby affecting the use. When the range of the gap between the limiting flange 121 and the outer side surface of the pen point 32 is greater than 0.1mm, the gap between the pen point 32 and the limiting flange 121 is too large, so that the limiting flange 121 cannot limit the pen point 32 in the writing process, and the lower end of the pen core 30 shakes to a greater extent to influence writing. In the application, the gap range value is set to be between 0.05mm and 0.1mm, so that the shaking amplitude generated in the writing process of the intelligent pen 10 can be reduced, the sensor 21 can be accurately triggered,

and the pen core 30 can be prevented from being stuck when the sensor 21 is triggered repeatedly, so that the intelligent pen 10 can write more smoothly.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
