Abstract

The invention discloses an anti-falling pen, relates to the field of stationery, and solves the problem that a pen point of a pen used in daily studying and working is prone to crashing. The anti-falling pen comprises a pen shell and a pen core mounted in the pen shell, and is characterized in that a moving sleeve is arranged on the front section of the pen core, an oblique pushing block is fixed on the outer wall of the moving sleeve, a reset spring is sleeved at the front end of the pen core, a pen core limiting portion is fixedly arranged in the pen shell, a pressing oblique pushing portion is arranged on the circumferential wall of the pen shell, and the pressing oblique pushing portion contacts the oblique pushing block. The anti-falling pen is convenient to use, when the anti-falling pen is held to write, the pen point automatically extends out of the pen core under the action of holding force; and when the anti-falling pen is not used, the pen point automatically contracts back into the pen shell, so that the pen point portion of the pen core is effectively protected and prevented from being crashed by falling.

Description

A kind of anti-fall pen

Technical field:

The present invention relates to the stationery field, relate in particular to a kind of anti-fall pen.

Background technology:

When daily study and office, pen is one of the most used stationery, and now the most frequently used is that nib is the signature pen of roll structure, and it is different that it complies with the ink composition that uses, and can be divided into water-based and oiliness.The ink that neutral signature pen uses is called again " gel ink pen " between water-based and oiliness.Although the signature pen that nib is roll structure uses flexibly, feel is better, easily breaks.In routine work study, pen often can drop from desk, in case nib lands, pen core will damage.

Summary of the invention:

Technical problem to be solved by this invention is to overcome the defective of prior art, and a kind of anti-fall pen that prevents that nib from breaking is provided.

Technical problem to be solved by this invention realizes by the following technical solutions.

A kind of anti-fall pen, comprise a shell and be contained in the interior pen core of a shell, it is characterized in that: described pen core leading portion is provided with movable sleeving, be fixed with oblique push block on the movable sleeving outer wall, described pen core front end sleeve has back-moving spring, be fixedly installed the pen core limiting section in described shell, be provided with the cant section of pressing on described shell circle wall, press cant section and contact with oblique push block.

The described cant section arranged outside of pressing has rubber blanket, the comfort when improving hand and being affectedly bashful.

Be fixed with rubber ring, the vibration when writing to reduce nib in the pen mouth of described shell front end setting.

The described cant section of pressing arranges one, more than two or three, presses cant section and be arranged on when writing hand and be affectedly bashful on the position of a shell.During use, hand is arrested pen, and finger is affectedly bashful and is being pressed in cant section, can be pressed in a shell pressing cant section, presses cant section front end pushing oblique push block, and movable sleeving is passed to pen mouth place together with pen core, and this moment, nib stretched out pen mouthful, can normally write; Used time not, unclamp the cant section of pressing, under the effect of back-moving spring, homing in this moment, nib retracted pen mouthful, can play the effect of protection nib to movable sleeving together with pen core, prevents from that pen from falling from eminence nib is broken.

Anti-fall pen provided by the invention, easy to use, when writeing with a pen word, pen core is the auto-extending nib under the effect of being affectedly bashful power, not the used time, in the pen with automatic retractable pen point shell, has effectively protected the tip of pen core, can prevent from after pen from falling, nib being broken.

Description of drawings:

Fig. 1 is structural representation of the present invention.

The specific embodiment:

For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram and embodiment, further set forth the present invention.

As shown in Figure 1, a kind of anti-fall pen of double, comprise a shell 9 and be contained in the interior pen core 8 of a shell 9, pen core 8 leading portions are provided with movable sleeving 4, be fixed with oblique push block 5 on movable sleeving 4 outer walls, pen core 8 front end sleeves have back-moving spring 3, be fixedly installed pen core limiting section 10 in shell 9, be provided with the cant section 6 of pressing on shell 9 circle wall, press cant section 6 and contact with oblique push block 5, pressing cant section 6 arranged outside has rubber blanket 7, the comfort when being affectedly bashful to improve hand, be fixed with rubber ring 2, the vibration when writing to reduce nib in the pen of shell 9 front end settings mouthful 1.

Above demonstration and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
