Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference numeral is as follows:
1-needle tubing; 11-head; 111-neck; 2-steel ball
Detailed description of the invention
Technical scheme of the present invention is further illustrated by specific embodiment below in conjunction with Fig. 1.
A kind of needle-tube pen-point, comprise needle tubing 1 and steel ball 2, one end of needle tubing 1 is provided with head 11, head 11 envelope steel ball 2 and the upper surface of steel ball 2 expose the upper surface of head 11, the height that the upper surface of steel ball 2 exposes the upper surface of head 11 is 0.1 ~ 0.2mm, and steel ball 2 coordinates with head 11 activity, and head 11 is provided with neck 111, steel ball 2 is positioned at the top of neck 111, and the minimum diameter of neck 111 is 0.15 ~ 0.2mm.The activity of head 11 and steel ball 2 coordinates, and the height that the upper surface of steel ball 2 exposes the upper surface of head 11 is 0.1 ~ 0.2mm, makes fluent writing, the minimum diameter of neck 111 is 0.15 ~ 0.2mm, can prevent ink from oozing out pollution file in a large number, structure of the present invention is simple, fluent writing.
In the present embodiment, the madial wall of head 11 is provided with several guiding gutters, and several guiding gutters are uniformly distributed ringwise, and the cross section of guiding gutter is semicircle.Guiding gutter be arranged so that the ink in needle tubing 1 more easily flows out, write more smooth.Preferably, the cross section of guiding gutter is semicircle, and in other embodiments, the cross section of guiding gutter also can select arc or other shapes.
In the present embodiment, the lateral wall of head 11 is tapered, and namely in the section shown in Fig. 1, the lateral wall of head 11 and the axis of needle tubing 1 are at an angle.Preferably, in the section shown in Fig. 1, extended line and the steel ball 2 of the lateral wall of head 11 are tangent, when this is arranged so that nib tilts to use, also can fluent writing, and the different user demands of user can be met.
