Abstract

A kind of novel pen, mainly include the hollow sleeve of pen and both ends open, it is conformed with on sleeve outer wall, it is provided with the groove to sleeve outer wall depression at sleeve lining, the ratchet that it is axle center symmetric arrays with the axis of sleeve that upper limb at groove is provided with, ratchet tilts to nib, after pen enters sleeve, ratchet plays the effect of firm pen, prevents pen from moving in sleeve；At projection outer wall parcel one circle erasing rubber, no matter carrying what pen, as long as the appliance for holding pen of the band erasing rubber of the present invention on overlapping outside pen, people just need not the most individually carry erasing rubber.

Description

A kind of novel pen

The application is filing date 2012 02 month 27, and patent name is " appliance for holding pen of band erasing rubber ", Patent No.: The division of the patent of 2012100458082.

Technical field

The present invention relates to a kind of novel pen, belong to office stationary articles for use field.

Background technology

When writing, people generally use thumb, forefinger and middle finger to hold a pen, owing to the position held a pen is uncertain, although have old Teacher, the indication of the head of a family, but the posture that a lot of people holds a pen is the most incorrect, is easily caused myopia, hunchback, and, due to hands and pen Contact area less, cause unit are pressure excessive, make finger and pen often in contact with position play callus.

A kind of nearsightedness-preventing pen sleeve is disclosed, by both ends open in the patent document of Application No. 201220002082.X Hollow sleeve and the platform composition that holds a pen of triangle cylindricality, successively by the standard gestures held a pen on three faces of the platform outer wall that holds a pen Be provided with cave inward thumb position, forefinger position, middle finger position, assist in user and hold a pen by correct posture, near with prevention Depending on, deficiency is that the use time one is long, and pen easily moves down in the pen cap, it is difficult to sleeve is fixed on position optimal on pen.

The kind of pen is a lot, and the most only pencil is with rubber sassafras, but in actual application, ball pen or pen are wrongly write Word, it is also desirable to using erasing rubber to correct mistake, this situation occur, people must be further provided with one piece of erasing rubber.But individually Carry erasing rubber inconvenient, easily lose.

It is, thus, sought for one can either prevent pen from moving in sleeve, the instrument of erasing rubber can be comprised again.

Summary of the invention

It is an object of the invention to provide one can either prevent pen from moving in sleeve, also with the pen of erasing rubber.

The technical scheme is that a kind of novel pen, mainly include the hollow sleeve 1 of pen and both ends open, sleeve 1 Being conformed with 11 on outer wall, be provided with the groove 12 to sleeve outer wall depression at sleeve 1 inwall, the upper limb at groove 12 is provided with set The ratchet that axis is axle center symmetric arrays 13 of cylinder, ratchet 13 tilts to nib；At projection 11 outer wall parcel one circle erasing rubber 2, pen enters sleeve from the top of sleeve 1, a body extruding ratchet 13, makes ratchet 13 crushed element enter groove 12, when pen puts in place, Ratchet 13 props up a body, makes pen reversely not move；Sleeve arranges finger position by normal place；Groove 12 is arranged on sleeve 1 The position that inwall is overlapping with the projection of projection 11；In the middle part of described projection 11, upper and lower end face is designed with a draw-in groove.

The inwall of erasing rubber 2 wraps the top of projection 11, and the annular bayonet socket of erasing rubber 2 inwall is stuck in the draw-in groove of projection 11 In, the inner wall shape of erasing rubber 2 is that negative and positive are mated with the shape of projecting tip.

Described projection 11 is the loop configuration around sleeve outer wall.

Erasing rubber 2 is near the one end open of sleeve 1 and is provided with the inwall to raised 11 top depression, the top of opening and Bottom is provided with the annular bayonet socket of projection respectively.

Beneficial effect:

1, being conformed with at sleeve outer wall, be provided with groove at sleeve lining, the upper limb at groove is provided with ratchet, and ratchet is to pen The direction of point tilts, and after pen enters sleeve, ratchet plays the effect of firm pen, prevents pen from moving in sleeve.

2, wrapping up erasing rubber on the outer wall of projection, no matter carry what pen, as long as at an overcoat upper bush, people are the most not With the most individually carrying erasing rubber.

Accompanying drawing explanation

Fig. 1 is the cut-away view of the present invention；

Fig. 2 is the top view of the present invention；

Fig. 3 is one embodiment of the present of invention.

Detailed description of the invention

As shown in Figure 1 and Figure 2, a kind of novel pen, mainly include the hollow sleeve of pen and both ends open, on sleeve 1 outer wall Being conformed with 11, be provided with the groove 12 to sleeve outer wall depression at sleeve 1 inwall, the upper limb at groove 12 is provided with in sleeve Axis is the ratchet 13 of axle center symmetric arrays, and ratchet 13 tilts to nib；At projection 11 outer wall parcel one circle erasing rubber 2.

Described projection 11 is the loop configuration around sleeve outer wall.

Groove 12 is arranged on the position that sleeve 1 inwall is overlapping with the projection of projection 11.

In the middle part of described projection 11, upper and lower end face is designed with a draw-in groove.

Erasing rubber 2 is near the one end open of sleeve and is provided with the inwall to projecting tip depression, the top of opening and under Portion is provided with the annular bayonet socket of projection respectively.

The inwall of erasing rubber 2 wraps the top of projection, and the annular bayonet socket of erasing rubber 2 inwall is stuck in the draw-in groove of projection 11 In, the inner wall shape of erasing rubber 2 is that negative and positive are mated with the shape of projecting tip.

Pen enters sleeve from the top of sleeve, a body extruding ratchet 13, makes ratchet 13 crushed element enter groove 12, works as pen Putting in place, ratchet 13 props up a body, makes pen reversely not move, and accordingly, stops firmly to suitable position when pen enters sleeve Time, ratchet 13 can play the effect of fastening pen, prevent sleeve from sliding on pen.

The present invention is applicable not only to pencil, applies also for other pens such as ball pen or pen, as long as the internal diameter of sleeve is suitable ?.Before using, penholder entering the suitable position of sleeve, under the fixation of ratchet, pen will not move in sleeve, finger Hold the finger position being located on sleeve by normal place, pre-myopic-preventing effect can not only be played, additionally it is possible to use when needed The erasing rubber being located at outside sleeve.

As shown in Figures 2 and 3, the internal via shape of sleeve, according to the change of shape of pen, can be cylindrical, it is also possible to be Hexagonal.

Above-described embodiment is intended merely to the purposes of the interpretation present invention, and is not limitation of the present invention, this technology The those of ordinary skill in field, in the essential scope of the present invention, makes a variety of changes or substitutes, also should belong to the guarantor of the present invention Protect category.
