Abstract

The utility model discloses a 6-prism pencil with a pencil point protecting cap. The 6-prism pencil consists of a 6-prism profile pencil 1, a 6-prism pencil point sheath 2 and a 6-prism eraser 3. A 6-prism horn tapered hole 22 of the 6-prism pencil point sheath 2 can be sleeved at the non-handwriting end of the 6-prism profile pencil 1 during handwriting, the 6-prism pencil point sheath 2 can be taken off from the non-handwriting end of the 6-prism profile pencil 1 after handwriting, and then the 6-prism pencil point sheath 2 can be sleeved at one end of the 6-prism profile pencil 1, wherein the end of the 6-prism profile pencil 1 is provided with a conical pencil point 12 by cutting; a 6-prism hole 23 is in slip fit with the profile of the 6-prism profile pencil 1; and as a circular bead 28 in the junction of a small round hole 25 and an inner end surface 24 of the 6-prism hole 23 is used for supporting the conical pencil point 12, a pencil point 11 is bridged in the small round hole 25 to be free from collision so as to reduce the bothersome event of pencil point breaking. At the moment, even if the 6-prism profile pencil falls down to the ground carelessly, the pencil point 11 can also be prevented from being collided.

Description

A kind of six water chestnut post pencils with the nib protective cap

Affiliated technical field

The utility model stationery ball pen, particularly a kind of six water chestnut post pencils with the nib protective cap.

Background technology

Six water chestnut post gabarit pencils are one of the most frequently used writing implements; Owing to possess easily with erasing rubber and wipe this alterability advantage that leaves no trace behind the writing; Liked by the pupil; Even adult's six water chestnut post gabarit pencils also commonly used are at work marked, worked out a draft, the annual six water chestnut post gabarit pencil consumptions in the whole world are more than 10,000,000,000.Six water chestnut post gabarit pencils in the past all do not have the six water chestnut post gabarit tip of a pencils of having fined away are equipped with protective device, often are the six water chestnut post gabarit pencils of just having fined away, and just accidentally fall on the ground and have been broken nib, very troublesome.

Summary of the invention

The purpose of the utility model provides a kind of six water chestnut post pencils with the nib protective cap; Can guarantee to the full extent that six water chestnut post gabarit pencils are not easy to let nib to being broken when falling on the ground; The technical solution that adopts is: a kind of six water chestnut post pencils with the nib protective cap; Form by six water chestnut post gabarit pencils 1, six water chestnut cylindricality nib sheaths 2 and six 3 of water chestnut cylindricality erasing rubbers; It is characterized in that: described six water chestnut cylindricality nib sheaths, 2 appearance integrals are six water chestnut cylinders, are with six water chestnut cylindricality erasing rubbers 3 on an end six water chestnut stomidiums 27, the inboard microcephaly of six water chestnut loudspeaker taper holes 22 of the other end and six water chestnut post holes, 23 smooth transition; The gabarit of six water chestnut post holes 23 and six water chestnut post gabarit pencils 1 is for being slidingly matched; And have small sircle hole 25 to link up mutually between six water chestnut stomidiums 27 and the six water chestnut post holes 23, inner end 24 intersections in small sircle hole 25 and six water chestnut post holes 23 have fillet 28 to be supported on written cone 12, make nib 11 face the sky frame and in small sircle hole 25, avoid collision.

Six water chestnut cylindricality nib sheaths 2 are slightly resilient rubber-plastics material.The material of six water chestnut cylindricality erasing rubbers 3 is a decontamination rubber.Six water chestnut post gabarit pencils 1 are the general pencils of gabarit six water chestnut cylindricalitys.

Can six water chestnut loudspeaker taper holes 22 of six water chestnut cylindricality nib sheaths 2 be enclosed within the non-end of writing of six water chestnut post gabarit pencils 1 when writing; Can be after writing with soon can six water chestnut cylindricality nib sheaths 2 taking off from the non-end of writing of six water chestnut post gabarit pencils 1; An end of cutting written cone 12 that is enclosed within six water chestnut post gabarit pencils 1 gets final product; The gabarit of six water chestnut post holes 23 and six water chestnut post gabarit pencils 1 is for being slidingly matched; Utilize inner end 24 intersections in small sircle hole 25 and six water chestnut post holes 23 to have fillet 28 to be supported on written cone 12, make nib 11 face the sky frame and in small sircle hole 25, avoid collision, take place thereby reduced bothersome disconnected written thing.Even at this time let six water chestnut post gabarit pencils fall on the ground because of carelessness, nib 11 still can be avoided collision.

The beneficial effect of the utility model is: adopts six water chestnut cylindricality nib sheaths 2 protection nibs 11, takes place thereby reduced bothersome disconnected written thing, and novel, make simply, do not have the troublesome operation step, and be convenient to make and promote.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described further: a kind of six water chestnut post pencils with the nib protective cap; Form by six water chestnut post gabarit pencils 1, six water chestnut cylindricality nib sheaths 2 and six 3 of water chestnut cylindricality erasing rubbers; Described six water chestnut cylindricality nib sheaths, 2 appearance integrals are six water chestnut cylinders; Be with six water chestnut cylindricality erasing rubbers 3 on one end, the six water chestnut stomidiums 27; The inboard microcephaly of six water chestnut loudspeaker taper holes 22 of the other end and six water chestnut post holes, 23 smooth transition, and have small sircle hole 25 to link up mutually between six water chestnut stomidiums 27 and the six water chestnut post holes 23.

The length of six water chestnut loudspeaker taper holes 22 is 10 millimeters, and the outer end major part two opposite side sizes of six water chestnut loudspeaker taper holes 22 increase 1 millimeter than inboard microcephaly's two opposite side sizes, the inboard microcephaly of six water chestnut loudspeaker taper holes 22 and six water chestnut post holes, 23 smooth transition; The two opposite side sizes in described six water chestnut post holes 23 and six water chestnut post gabarit pencils, 1 gabarit, two opposite side sizes system are slightly with tight being slidingly matched, and six water chestnut post holes 23 are 15 millimeters to the degree of depth of its bottom 24; The diameter of described small sircle hole 25 is 4 millimeters, and length is 10 millimeters; Two opposite side of described six water chestnut stomidiums 27 are of a size of 8 millimeters, and six water chestnut stomidiums 27 are 5 millimeters to the degree of depth of its bottom 26; The radius of small sircle hole 25 and six water chestnut post holes, 23 inner ends, 24 intersection fillets 28 is 2 millimeters.

Can six water chestnut loudspeaker taper holes 22 of six water chestnut cylindricality nib sheaths 2 be enclosed within the non-end of writing of six water chestnut post gabarit pencils 1 when writing, so as not to seeking the time spent.Can be after writing with soon can six water chestnut cylindricality nib sheaths 2 taking off from the non-end of writing of six water chestnut post gabarit pencils 1; The nib of sharpening that is enclosed within six water chestnut post gabarit pencils 1 again will be write an end and got final product; Even at this time let six water chestnut post gabarit pencils fall on the ground because of carelessness; Rely on the support of the written cone 12 on the

small sircle hole
