Abstract
The utility model aims at providing a cylindrical pencil with a point sheath, which comprises a cylindrical pencil 1, a cylindrical pencil point sheath 2 and a cylindrical eraser 3; during writing, horn-shaped conical hole 22 of the cylindrical pencil point sheath 2 is sheathed on a non-writing end of the cylindrical pencil 1; after the writing, the cylindrical pencil point sheath 2 can be taken down from the non-writing end of the cylindrical pencil 1, and then is sheathed at one end of the cylindrical pencil 1, which is cut into a pencil point cone 12; a round cylinder hole 23 is in sliding fit with an excircle of the cylindrical pencil 1; a round corner 28 which is arranged between the intersecting part of a small round hole 25 and an inner end surface 24 of the round cylinder hole 23 is supported on the pencil point cone 12, so as to enable a pencil point 11 to be erected in the small round hole 25 in an overhead way and be prevented from being collided, so that the worrisome condition that the pencil point is broken can be reduced; and at the moment even if the cylindrical pencil drops onto the ground carelessly, the pencil point 11 also can be prevented from being collided.
Description
Affiliated technical field
The utility model stationery ball pen, particularly a kind of cylindrical pencil with the nib protective sleeve.
Background technology
Cylindrical pencil is one of the most frequently used writing implement; 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 cylindrical pencil also commonly used is at work marked, worked out a draft, the annual cylindrical pencil consumption in the whole world is more than 10,000,000,000.Cylindrical pencil does not in the past all have the cylindrical tip of a pencil of having fined away is equipped with protective device, often is the cylindrical pencil of just having fined away, and just accidentally falls on the ground and has been broken nib, very troublesome.
Summary of the invention
The purpose of the utility model provides a kind of cylindrical pencil with the nib protective sleeve; Can guarantee to the full extent that cylindrical pencil is not easy to let nib to being broken when falling on the ground; The technical solution that adopts is: a kind of cylindrical pencil with the nib sheath; Be made up of cylindrical pencil 1, cylindrical nib sheath 2 and 3 of cylindrical erasing rubbers, described cylindrical nib sheath 2 appearance integrals are cylinder, are with cylindrical erasing rubber 3 on the circular stomidium 27 of an end; The aperture tight fit of the diameter of cylindrical erasing rubber 3 and circular stomidium 27; The inboard microcephaly of the tubaeform conical bore 22 of the other end and circular columns hole 23 smooth transition, the cylindrical of circular columns hole 23 and cylindrical pencil 1 are for being slidingly matched, and have small sircle hole 25 to link up mutually between circular stomidium 27 and the circular columns hole 23; Small sircle hole 25 has fillet 28 to be supported on written cone 12 with inner end 24 intersections in circular columns hole 23, makes nib 11 face the sky frame and in small sircle hole 25, avoids collision.
Can the tubaeform conical bore 22 of cylindrical nib sheath 2 be enclosed within the non-end of writing of cylindrical pencil 1 when writing; Can be after writing with soon can cylindrical nib sheath 2 taking off from the non-end of writing of cylindrical pencil 1; An end of cutting written cone 12 that is enclosed within cylindrical pencil 1 gets final product; The cylindrical of circular columns hole 23 and cylindrical pencil 1 is for being slidingly matched; Utilize the small sircle hole 25 and inner end 24 intersections in circular columns hole 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 cylindrical pencil fall on the ground because of carelessness, nib 11 still can be avoided collision.
The beneficial effect of the utility model is: adopts cylindrical nib sheath 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 cylindrical pencil with the nib sheath; Form by cylindrical pencil 1, cylindrical nib sheath 2 and 3 of cylindrical erasing rubbers; Cylindrical nib sheath 2 appearance integrals are cylinder; Be with cylindrical erasing rubber 3, the aperture tight fit of the diameter of cylindrical erasing rubber 3 and circular stomidium 27, the inboard microcephaly of the tubaeform conical bore 22 of the other end and circular columns hole 23 smooth transition on the circular stomidium 27 of one end; The cylindrical of circular columns hole 23 and cylindrical pencil 1 is for being slidingly matched; And have small sircle hole 25 to link up mutually between circular stomidium 27 and the circular columns hole 23, small sircle hole 25 has fillet 28 to be supported on written cone 12 with inner end 24 intersections in circular columns hole 23, makes nib 11 face the sky frame and in small sircle hole 25, avoids collision.
Can the tubaeform conical bore 22 of cylindrical nib sheath 2 be enclosed within the non-end of writing of cylindrical pencil 1 when writing; Can be after writing with soon can cylindrical nib sheath 2 taking off from the non-end of writing of cylindrical pencil 1; An end of cutting written cone 12 that is enclosed within cylindrical pencil 1 gets final product; The cylindrical of circular columns hole 23 and cylindrical pencil 1 is for being slidingly matched; Utilize the small sircle hole 25 and inner end 24 intersections in circular columns hole 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 cylindrical pencil fall on the ground because of carelessness, nib 11 still can be avoided collision.
