Summary of the invention
Technical problem to be solved in the utility model is the defective that remedies above-mentioned prior art, and a kind of blind person writing drawing double-purpose pen is provided.
Technical problem of the present utility model is solved by the following technical programs.
This blind person writing drawing double-purpose pen, handwriting comprises that the blind person uses lettering pen.
The characteristics of this blind person writing drawing double-purpose pen are:
Described blind person is half of described handwriting with lettering pen, comprise and write penholder, and to be provided with an end inwall is the sheath rod of internal thread, and described blind person is that an end of internal thread pierces into the penholder of writing of lettering pen from the sheath rod inwall.
Second half of described handwriting is that the blind person uses drawing pen, described blind person comprises the drawing penholder with drawing pen, described drawing penholder tail end is provided with the external screw thread that engages with the internal thread of described sheath rod, described blind person is that the threaded one end of internal thread is connected with the drawing penholder of drawing pen and sheath rod inwall, so with described blind person with lettering pen constitute that two tail ends dock mutually, lettering pen core print and drawing pen core print be respectively at the integrated double-purpose pen at both ends.
Technical problem of the present utility model is solved by following further technical scheme.
Described blind person comprises also that with lettering pen being positioned at described blind person's usefulness of writing penholder writes the tip of stylus cover of pen core, lettering pen masthead end, and writes pen core extension and contraction control mechanism.
Described blind person comprises also that with drawing pen the blind person who is positioned at described drawing penholder uses the drawing pen nib cover of drawing pen core, drawing pen masthead end, and drawing pen core extension and contraction control mechanism.
Technical problem of the present utility model is solved by following further again technical scheme.
The described pen core extension and contraction control mechanism of writing comprises the lettering pen runner of writing pen core back-moving spring and band hangers, and the draw-in groove of tip of stylus cover tail end, and described lettering pen rotaring wheeling sleeve is inserted in the end of writing pen core.When penholder was write in rotation, the hangers of lettering pen runner broke away from the draw-in groove of tip of stylus cover tail end, write the pen core back-moving spring and drove and write pen core and stretch out use from the outlet of tip of stylus cover; When counter-rotation was write penholder, the hangers of lettering pen runner entered tip of stylus cover tail end draw-in groove, write the pen core back-moving spring and drove the outlet of writing pen core indentation tip of stylus cover and reset.
Described drawing pen core extension and contraction control mechanism comprises the drawing pen runner of drawing pen core back-moving spring and band hangers, and the draw-in groove of drawing pen nib cover tail end, and described drawing pen rotaring wheeling sleeve is inserted in the end of drawing pen core.When rotating the drawing penholder, the hangers of drawing pen runner breaks away from the draw-in groove of drawing pen nib cover tail end, and drawing pen core back-moving spring drives the drawing pen core and stretches out use from the outlet of drawing pen nib cover; During counter-rotation drawing penholder, the hangers of drawing pen runner enters drawing pen nib cover tail end draw-in groove, and the outlet that drawing pen core back-moving spring drives drawing pen core indentation drawing pen nib cover resets.
Described blind person is that nib is the pen core of writing of spheroidal with writing pen core.The braille salient point of writing out is fuller, more wear-resisting.
Described tip of stylus cover and described writing are provided with case ring between the penholder.
Be provided with case ring between described drawing pen nib cover and the described drawing penholder.
The beneficial effect that the utility model is compared with the prior art is:
The utility model links to each other the blind person and becomes one with the two kinds of penholder tail ends of writing, paint, two kinds of nibs at two ends can provide one of blind person dual-purpose, can shrink nib by rotation, be convenient to not only that the blind person carries and safekeeping, and the stylus point be not exposed to the outside, the blind person can because of look the barrier not be scratched.Write nib and change outstanding more spheroidal into, can make the braille salient point of writing out fuller, more wear-resisting, more easy to identify.
The specific embodiment
Below in conjunction with the specific embodiment and contrast accompanying drawing method of the present utility model is described.
A kind of blind person writing drawing double-purpose pen as shown in the figure, comprise that the blind person uses lettering pen, the blind person comprise with lettering pen write penholder 6, be positioned at the nib of writing penholder 6 be spheroidal the blind person with write pen core 10, write penholder 6 tops tip of stylus cover 5, write the lettering pen runner 12 of pen core back-moving spring 11 and band hangers, lettering pen runner 12 covers are inserted in the end of writing pen core 10, tail end at tip of stylus cover 5 is provided with draw-in groove, with the hangers of lettering pen runner 12, write pen core back-moving spring 11 and form and write pen core extension and contraction control mechanism.Be provided with the sheath rod 1 that the tail end inwall is an internal thread writing penholder 6 outer walls.
Penholder 6 is write in rotation, the hangers of lettering pen runner 12 breaks away from tip of stylus and overlaps 5 tail end draw-in grooves, writing pen core back-moving spring 11 drives and writes pen core 10 and stretch out use from the outlet of tip of stylus cover 5, counter-rotation is write penholder 6, the hangers of lettering pen runner 12 enters tip of stylus and overlaps 5 tail end draw-in grooves, writes pen core back-moving spring 11 and drives the outlet of writing pen core 10 indentation tip of stylus cover 5 and reset.
Comprise that also the blind person uses drawing pen, the blind person comprises that with drawing pen tail end is the externally threaded drawing penholder 7 that is connected with the tail end internal thread of sheath rod 1, the blind person who is positioned at drawing penholder 7 uses drawing pen core 4, the drawing pen nib cover 9 on drawing penholder 7 tops, case ring 8 between drawing pen nib cover 9 and the drawing penholder 7, the drawing pen runner 2 of drawing pen core back-moving spring 3 and band hangers, drawing pen runner 2 covers are inserted in the end of drawing pen core 4, tail end at drawing pen nib cover 9 is provided with draw-in groove, with the hangers of drawing pen runner 2, drawing pen core back-moving spring 3 is formed drawing pen core extension and contraction control mechanism.To stretch out direction opposite with writing pen core with stretch out direction and the blind person of drawing pen core for the blind person.
Rotate drawing penholder 7, the hangers of drawing pen runner 2 breaks away from the draw-in groove that drawing pen nib overlaps 9 tail ends, drawing pen core back-moving spring 3 drives drawing pen core 4 and stretches out use from the outlet of drawing pen nib cover 9, counter-rotation drawing penholder 7, the hangers of drawing pen runner 2 enters drawing pen nib and overlaps 9 tail end draw-in grooves, and the outlet that drawing pen core back-moving spring 3 drives drawing pen core 4 indentation drawing pen nibs cover 9 resets.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; and performance or purposes are identical, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
