Description

The automatic lead sweat pen of nib knock-type

Technical field

The utility model relates to a kind of by ball pen nib pressing feeding lead for retractable pencil or make piston touch that nib ejects lead for retractable pencil and write pressure sensitive and the writing function a kind of dual-purpose writing implement commonly used of ball pen by the pressing movable part on carrying agents such as books, desk.

Background technology

Pencil, ball pen are the writing implements of using always, and it mostly only at one end is provided with nib, do not possess multiple writing element, function singleness simultaneously; The general volume of existing writing implement is big, carry inconvenience, effort is write, write to ink reservoir volume, core storage amount lowlyer, not anti-, use inconvenience.

In order to overcome the problems referred to above, people many technological inventions.As: Chinese patent ZL00251161.4 " double-purpose pen ", Chinese patent ZL01207884.0 " a kind of steel, hair double-purpose pen ", Chinese patent ZL20042005766.1 " ball pen of band pencil stub " etc. have its merits and demerits separately.

Summary of the invention

In order to overcome the existing problem of existing writing implement, the purpose of this utility model provides a kind of two kinds of automatic lead sweat pens of writing function written knock-type commonly used that have, and it is that written parts pressing on books or desk by refill for ball-point pen ejects lead for retractable pencil or makes piston touch the propelling pencil that band that nib ejects lead for retractable pencil is write pressure inductor by the pressing movable part.

To achieve these goals, the technical solution of the utility model is as follows: the automatic lead sweat pen of written knock-type comprises penholder, pen cap, cap, movable cap decoration, refill for ball-point pen, piston; An end that it is characterized in that penholder is provided with internal thread and is connected with the pen cap external screw thread, the other end of penholder is together fastening with the point cover, refill for ball-point pen is housed in the penholder, pen core outer lining sleeve pipe and pencil machine core, pencil machine core is by the outer lining sleeve pipe, spring, two pawl dops, clamp ring, core storage tube, lead for retractable pencil is formed, wherein, the grafting aperture is arranged in the outer lining sleeve pipe and be provided with two chambeies up and down, interior and the spring of epicoele, core storage tube, two pawl dop tail ends are connected, interior and the clamp ring of cavity of resorption, two pawl dop head ends are connected, two pawl dop tail ends pass clamp ring, penetrate the grafting aperture from cavity of resorption and enter epicoele, pass spring again and be connected with core storage tube, clamping has lead for retractable pencil in the two pawl dops; Rubber resistance circle is connected with retaining core pipe, at first moves in the point cover from the penholder upper port, moves into pencil machine core, pen core outer lining sleeve pipe and refill for ball-point pen from the penholder upper port again, screws on pen cap at last, fixedly ball pen nib and pen core outer lining sleeve pipe; During use, cap is pulled out, can write the ball pen word, write pressure inductor, mainly the spring force by pencil machine core produces with writing the pressure acting in conjunction, when writing pressure when excessive, spring shrinks, the terminal that holds a pen moves down, write pressure when too small, spring maintains the original state, the terminal that holds a pen will keep normally writing pressure, utilize this principle to regulate automatically and write pressure, greatly solve effort and write problem, if need drawing pencil word, can be by the ball pen nib at books, pressing or make piston touch the ball pen nib by the movable cap decoration of pressing to eject lead for retractable pencil on the desk, circle pinning and lead for retractable pencil are released a segment distance together because two pawl dops are locked, put pressing power, under the effect of spring, two pawl dop head ends begin to shrink back, and the drive clamp ring retreats together, lead for retractable pencil is because the frictional force of rubber resistance circle is motionless more greatly and still, retreated a segment distance after, clamp ring is blocked slack by outer lining sleeve pipe cavity of resorption panel, meanwhile two pawl dop head ends begin in clamp ring inside to shrink, when two pawl dop heads all enter clamp ring, just recovered original folder lead for retractable pencil power, pressing so moves in circles, can eject needed lead for retractable pencil length, the transposing nib can be used; When lead for retractable pencil is not enough, can recall to nib and continue pressing, eject needed lead for retractable pencil length, during the change-fountain pen core, pressing ball pen nib or the movable cap decoration of pressing on the books desk take out remaining lead for retractable pencil from the retaining core pipe mouth earlier, change to new lead for retractable pencil, put pressing power then, recover original folder lead for retractable pencil power.

The utility model is simple in structure, good looking appearance, volume are little, easy to carry, one dual-purpose, ink reservoir volume is moderate, anti-writing, the lead sweat pen can be converted to the usefulness of single pens such as gel ink pen, propelling pencil, liquid pencil, be provided with and write pressure inductor, can reach and write the leicht fallen D/A effect, be fit to pencil mapping commonly used, write aspects such as ball pen word, pencil word, liked by different crowd.
