Be additionally provided with pen core cutting apparatus, the pen core cutting apparatus includes sliding part, adjustment portion and pen core cutting edge, the sliding part with
The body part is slidably connected, the axis of the glide direction of the sliding part perpendicular to the fraising；The pen core cutting edge hinge
It connects in one end of sliding part, pen core cutting edge is located at the small end of the fraising, and the pivot center of pen core cutting edge is perpendicular to described
The axis of fraising；The adjustment portion includes connecting rod, operating stick and reset spring, and the operating stick is hinged on the another of sliding part
End, one end of the connecting rod and pen core cutting edge hingedly, the other end and operating stick it is hinged, the reset spring is connected to pen core and cuts
It cuts between sword and operating stick.
Further, the sliding part includes slide bar, and the operating stick, connecting rod, pen core cutting edge and slide bar constitute plane
Four-bar mechanism.
Further, the body part is equipped with limited block, and the sliding part is equipped with compatible with the limited block
Limited block.
Preferably, there are two the reset springs, described two reset springs are parallel to each other, described two reset springs point
The two sides of the sliding part are not set symmetrically.
Further, the body part is equipped with the transparent window for observing pen core cutting edge.
Further, the body part is equipped with pilot hole, and pilot hole is connected to the big end of the fraising, and pilot hole is circle
Cylindricality, pilot hole and fraising coaxial line.
In use, the material removal that rotation pencil wraps up handwriting cutting edge will on pen core, while being seen by transparent window
The length of part can be used by examining pen core；Pen core cutting edge is pushed at pen core by push operation bar, then passes through rotation operating stick
Pen core cutting edge is adjusted to suitable angle；Pen core is continued to rotate, pen core cutting edge is then completed the cutting to pen core, finally obtained
Pen core with certain acuity.
By adopting the above technical scheme, since fraising is frustroconical, pen core is pierced by by the small end of fraising
Fraising can need voluntarily to control so that the length available part of pen core is no longer fixed according to using；Pen core cutting apparatus
Setting, the acuity of the available part of pen core is voluntarily adjusted as needed.The present invention has easy to operate, tune
Save the random feature of angle.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 uses schematic diagram for of the invention.
In figure: 1- body part, 2- fraising, 3- notch, 4- handwriting cutting edge, 5- sliding part, 6- adjustment portion, the cutting of 7- pen core
