Further, the nib main part that the conical bright pointed type nib main part of nib main part set up, the nib main part is symmetrical structure.

Furthermore, the writing particles are arranged in a spherical mode, and the diameter of each writing particle is provided with a model option of 0.2-0.8 mm according to the thickness of the handwriting.

Furthermore, the width of the capillary gap is 100-120 μm, and different widths of the capillary gap can be selected according to different writing particle diameters.

Furthermore, the pressing sheet is made of a memory alloy material.

The utility model adopts the above structure gain beneficial effect as follows: the utility model provides a pair of CVD nib simple structure, through to CVD diamond integrated into one piece, avoid the fragile shortcoming of junction, and nib point portion changes the convenience, need not extract the nib main part is whole, and simultaneously, the CVD diamond is superhard materials to CVD diamond preparation nib has powerful wear-resistant performance, has solved the difficult problem that traditional nib easily worn and torn.
