Detailed description of the invention

Please refer to shown in Fig. 1 to Fig. 3, the concrete structure that it has demonstrated first preferred embodiment of the utility model, includes a body 10, pen core 20 and cap 30.

Wherein, the diameter of described body 10 is 20mm, not to be limited, this pen core 20 is arranged in a body 10, and the nib 21 of pen core 20 stretches out outside a body 10, and these cap 30 close-fittings are linked in the end of a body 10 and cover nib 21, and, two end lateral surfaces of this body 10 are provided with waveform guiding step 11, inner end 31 undulates of this cap 30 accordingly, and the inner end 31 of cap 30 is suitable and be butted on waveform guiding step 11 with waveform guiding step 11.

In the present embodiment, this pen core 20 is one, and it is circle pen core, and it also can be flat pen core certainly, and not to be limited, described pen core 20 is water fillable, not to be limited.And the nib 21 of this pen core 20 stretches out the front end of a body 10, the rear end of a body 10 is provided with pen plug 40, and the tail end of pen core 20 is butted on the inner end of pen plug 40, and in the present embodiment, this pen plug 40 is installed on the rear end of a body 10 by screw-in version.

When assembling, first pen core 20 is put into a body 10, make nib 21 stretch out the front end of a body 10, then, pen plug 40 is screwed togather to the rear end that is installed on a body 10, then, cap 30 close-fittings are linked in to the leading section of a body 10 and cover nib 21.
