Abstract

A pen with an eraser mainly comprises a pen body and a hollow sleeve, wherein the two ends of the hollow sleeve are opened. a protrusion is arranged on the outer wall of the sleeve, a groove concaved towards the outer wall of the sleeve is formed in the inner wall of the sleeve, pawls symmetrically arranged with an axis line of the sleeve as the center are arranged on the upper edge of the groove, the pawls incline towards the pen tip, and after the pen body enters the sleeve, the pawls can stabilize the pen body and prevent the pen body from moving in the sleeve. The outer wall of the protrusion is wrapped by a circle of the eraser. No matter which kind of pen a person carries, the person does not need to carry an eraser independently as long as a pen is sleeved with the pen comprising the eraser.

Description

A kind of pen with erasing rubber

Technical field

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

Background technology

When writing, people use thumb, forefinger and middle finger to hold a pen usually, because the position held a pen is uncertain, although there is the indication of teacher, the head of a family, the posture that a lot of people holds a pen is still incorrect, easily causes myopia, hunchback, and, because the contact area of hand and pen is less, cause unit are pressure excessive, callus is played at the position that finger and pen are often contacted.

Be disclose a kind of nearsightedness-preventing pen sleeve in the patent document of 201220002082.X at application number, be made up of the hollow sleeve of both ends open and the platform that holds a pen of triangle cylindricality, on three faces of the platform outer wall that holds a pen successively by the standard gestures held a pen be provided with cave inward thumb position, forefinger position, middle finger position, contribute to helping user to hold a pen by correct posture, with pre-myopia prevention, deficiency is that service time one is long, pen easily moves down in the pen cap, is difficult to sleeve to be fixed on position best on pen.

The kind of pen is a lot, usually only have pencil with rubber sassafras, but in the application of reality, word is wrongly write by ball pen or pen, also needs to use erasing rubber to correct a mistake, and occur this situation, people must be equipped with one piece of erasing rubber in addition.But carry separately erasing rubber inconvenience, easily lose.

Therefore, need to find one and can either prevent pen from moving in sleeve, the instrument of erasing rubber can be comprised again.

Summary of the invention

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

Technical scheme of the present invention is: a kind of pen with erasing rubber, mainly comprise the hollow sleeve 1 of pen and both ends open, sleeve 1 outer wall is provided with projection 11, is provided with the groove 12 to sleeve outer wall depression at sleeve 1 inwall, be provided with ratchet 13 at the upper limb of groove, ratchet 13 tilts to nib; At projection 11 outer wall parcel one circle erasing rubber 2, pen enters sleeve from the top of sleeve, body extruding ratchet 13, and make ratchet 13 crushed element enter groove 12, when pen puts in place, ratchet 13 props up a body, makes pen can not oppositely movement; Sleeve is arranged by normal place and refers to position.

Described ratchet 13 with the axis of sleeve for axle center symmetric arrays.

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, and the inner wall shape of erasing rubber 2 is that negative and positive are mated with the shape at projection 11 top.

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

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

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

Erasing rubber 2 near sleeve one end open and be provided with to projecting tip depression inwall, the upper and lower of openend is respectively equipped with towards the annular bayonet socket of projection.

Described pen is identical with the internal via shape of sleeve, is cylindrical or hexagon.

Beneficial effect:

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

2, on the outer wall of projection, wrap up erasing rubber, no matter carry what pen, as long as at an overcoat upper bush, people just need not carry erasing rubber separately again.

Accompanying drawing explanation

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

Fig. 2 is 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 pen with erasing rubber, mainly comprise the hollow sleeve of pen and both ends open, sleeve 1 outer wall is provided with projection 11, the groove 12 to sleeve outer wall depression is provided with at sleeve 1 inwall, at the upper limb of groove 12 ratchet 13 that to be provided with the axis of sleeve be axle center symmetric arrays, 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.

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, and the inner wall shape of erasing rubber 2 and the shape of projecting tip are that negative and positive are mated.

Pen enters sleeve from the top of sleeve, body extruding ratchet 13, ratchet 13 crushed element is made to enter groove 12, when pen puts in place, ratchet 13 props up a body, makes pen can not oppositely movement, accordingly, when pen enter sleeve stop firmly to suitable position time, ratchet 13 can play the effect of fastening pen, prevents sleeve from sliding on pen.

The present invention is not only applicable to pencil, is also applicable to other pens such as ball pen or pen, as long as the internal diameter of sleeve is suitable.Before using, penholder is entered the position that sleeve is suitable, under the fixation of ratchet, pen can not move in sleeve, finger holds the finger position be located at by normal place on sleeve, can not only play pre-myopic-preventing effect, can also use the erasing rubber be located at outside sleeve when needed.

As shown in Figures 2 and 3, the internal via shape of sleeve, according to the change in shape of pen, can be columniform, also can be hexagonal.

Above-described embodiment is only used to interpretation purposes of the present invention, and is not limitation of the present invention, those skilled in the art, in essential scope of the present invention, makes a variety of changes or substitutes, also should belong to protection category of the present invention.
