Abstract
The invention discloses a pencil positioning mechanism for a pencil sharpener. The pencil positioning mechanism comprises a shell, an openable cover is arranged in the shell, the pencil sharpener is fixedly arranged in the shell, a fixing seat with a through hole is arranged at the inner bottom of the cover, and the through hole is movably connected with a positioning sleeve which is movably connected with a pencil. The pencil positioning mechanism for the pencil sharpener has the advantages of simplicity in processing, precision in fitting, convenience in use and capability of well positioning the pencil.
Description
Technical field
The present invention relates to stationery, particularly pencil-knife.
Background technology
Pencil-knife is that the use of a kind of people frequent stationery, particularly students in middle and primary schools that use is maximum.Existing pencil-knife have a class be manual be pencil sharpener, another kind of is by the plane pencil-knife (also comprising electronic) of pencil of machine driving, this class pencil-knife is because the relation of structure has configured a housing, clamps pencil and planes like this with regard to the jaw of clamping lead pen is set.No matter with the pencil-knife of manual or motor-driven (electronic) pencil of planing, all wish the lead for retractable pencil of pencil once reaching certain length and well-balanced tapering in planing, with the existing particularly pencil-knife of a manual class (being pencil sharpener) be difficult to plane out lead for retractable pencil certain length and well-balanced tapering.In existing this class pencil-knife, settle the planing position of blade to be provided with the endoporus of a tapering, in the time of planing pencil, one termination point casing of pencil is entered in the endoporus of tapering and withstand, rotate while advance the pencil pencil of planing, while planing like this pencil, the axis centre of pencil is difficult to keep balance, remains in the axis centre of pencil that the several number of degrees of lower deviation are also difficult to.Adult is when with existing these pencil-knife planing pencils, also be the pencil of planing in the several number of degrees of lower deviation in the axis centre of pencil, the axis that also will often adjust pencil does not depart from too much, do not make the pen core of pencil interrupt in planing, otherwise a rabbet plane, the disconnected pen core in one side, a pencil planing is over, and also can not dig a more well-balanced pen core that has certain length, the pencil in addition students in middle and primary schools plane.It during with existing these pencil-knifes (being pencil sharpener) planings pencil, is all rotation pencil at leisure, rotation pencil is planed on one side, the axis centre (level or vertical) of adjusting pencil on one side does not depart from too many, in the time that having interrupted pen core, pencil planing just then digs again, until pen core digs to write.Add pen core concentricity bad, quality poor pencil again, the pencil of at this moment planing is the time-consuming pencil of wasting again.
Up to the present the pencil-knife of manual planing pencil (being pencil sharpener), be all the taper inner that pencil one termination is directly packed into planing pencil, the axis centre position of adjusting pencil by people oneself pencil of planing.
Summary of the invention
When technical problem to be solved by this invention, provide a kind of simple in structure, easy to use, handling ease, and can realize the pencil detent mechanism that makes pencil can keep the little pencil-knife in axis center or deviation center, positioning sleeve wherein also can be used in and in motor-driven or electric pencil planer, locate better pencil.For solving the problems of the technologies described above, the technical solution adopted in the present invention is: the pencil detent mechanism of pencil-knife, comprise pencil-knife, housing, in housing, be provided with the lid of folding, pencil-knife fixed in position is in housing, described lid inner bottom surface is provided with positioning seat, described positioning seat is provided with the endoporus of perforation, described endoporus is flexibly connected positioning sleeve 5 or 6, and described positioning sleeve 5 is provided with hexagonal inner via hole, and described positioning sleeve 6 is provided with circular inner via hole, in the endoporus of described holder, close on position, top and be provided with groove, and be provided with the criss-cross open slot of certain length.The outer round surface of described positioning sleeve 5 and 6 is provided with the boss muscle of the precision activity cooperation of respective slot
The beneficial effect of the pencil detent mechanism of pencil-knife of the present invention is: holder has certain length, accurate movable cooperation of the endoporus of holder and the cylindrical of positioning sleeve, the endoporus of positioning sleeve 5 and positioning sleeve 6 is chosen according to the pencil that will plane, it is also very little making the endoporus of positioning sleeve and pencil profile coordinate the tolerance of this cooperation, when pencil packs into and planes in the taper inner of planing like this, the axis centre position that pencil just can remain on pencil is not easy to depart from, it is accurate that the excircle dimension of pencil does, just does not depart from the axis centre position of pencil in positioning sleeve, in the time of planing pencil, just often do not adjust like this center of pencil axis, just the pencil tapering of writing of planing out, pen core can easily not dig again disconnected, the time of planing is short again, also save pencil, having changed manual pencil-knife does not have the planing present situation of pencil location.Positioning sleeve 5 and 6 can exchange and pack into holder.

Detailed description of the invention
As shown in Figure 1, existing manual pencil-knife great majority are all positioned in a housing, and some or the housing of certain moulding have formed an overall pencil-knife.The benefit of such pencil-knife is that the bits of pencil planing are collected in housing, has kept the clean of environment.But they all do not have the detent mechanism of pencil.Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing, as shown in Figures 2 to 6, housing 1 is settled pencil-knife 3, described housing 1 lid that is connected through the hinge, in described lid 2, be provided with holder 4, described holder 4 is provided with the round endoporus 4-1 of the perforation of the taper inner of corresponding pencil-knife, described round endoporus 4-1 is flexibly connected positioning sleeve 5 or 6, (this illustrate two planing holes pencil-knife), the bottom part that closes in the round endoporus 4-1 of described holder 4 is provided with groove A, and be provided with the criss-cross open slot 4-2 of certain length, the outer round surface of described positioning sleeve 5 and 6 is provided with the boss muscle C of the precision activity cooperation of respective slot A, described positioning sleeve 5 is provided with hexagonal inner via hole 5-1, described positioning sleeve 6 is provided with interior round tube hole 6-1, described inner via hole 5-1 and 6-1 be the movable appearance and size that coordinates pencil, described positioning sleeve 5 and 6 can exchange in the endoporus 4-1 being enclosed within holder 4.
Choose positioning sleeve according to pencil profile pencil encased and be enclosed within the endoporus of holder, just make pencil location, the axis of pencil just remains on a center, and pencil enters in the taper inner of planing rotation pencil or positioning sleeve has just been planed pencil.Holder and positioning sleeve reach by plastic cement injection moulding the precision that accurate activity coordinates, and have positioning sleeve to locate pencil and plane with regard to the not frequent axis centre position of adjusting pencil, save time and dig well, and pencil-lead is not easy again to dig disconnected, and pencil is located better.
