In the specific implementation, the main support can be adopted, so that all parts in the pen body can be conveniently placed, and the assembly and the production are convenient. The guide rail is positioned on the inner wall of the pen body or the inner wall of the main support.

The front end of the pen core comprises a metal part, and the signal transmitting end of the control circuit board is communicated with the metal part. The pen refill is one of a ball pen refill, a steel pen refill, a neutral pen refill and a metal pen refill. The ball-point pen refill may be a plastic refill with a metallic nib (the metallic nib is a metal part), or a ball-point pen refill with an all-metal refill (the all-metal refill is a metal part). The nib part of the steel pen refill is metal, namely the metal nib is a metal part. The gel ink pen refill and the ball pen refill have similar structures. The metallic pencil lead is made of alloy material, and has the features of conductivity, hardness and no need of sharpening. The present utility model preferably employs an all-metal body ballpoint pen refill, i.e., all-metal body ballpoint pens are exemplified in fig. 1-5.
