Abstract
The utility model relates to a novel rotary knife of a pencil sharpening machine. The novel rotary knife comprises a rotary knife with a shaft hole, which is arranged in a machine body; a plurality of spiral knife edges integrally connected with rotary knife is arranged on the outer surface of the rotary knife; the entire rotary knife is cylindrical; a gear is arranged at one end of the rotary knife; and the end of the rotary knife, which is connected with the gear, is tapered. The utility model has the characteristics that a pencil sharpened by the rotary knife has an appropriate taper, a section of pencil lead with basically-equal diameters is provided at a pen point, the writing time is long, the probabilities of thickening and tip breaking are low, the structure is simple, and the cost is low.
Description
Technical field
The utility model relates to a kind of pencil sharpener, particularly a kind of pencil sharpener New Kind of Hob.
Background technology
The pencil sharpener of selling on the existing market, the hobboing cutter that is provided with in the body are identical cylindrical of diameter, and its tip of a pencil that is whittled into is point relatively, easily disconnected point in the writing process, or the pencil vertebra degree of cutting out is big, write a period of time after, there is the short drawback of one-pen writing time in the very fast chap of nib.Though different manufacturers improves by the modes such as angle of adjusting hobboing cutter length and hobboing cutter and working face, increase writing time with the tapering of adjusting the pencil nib of being cut, the nib of being cut out is still very sharp, fractures easily.The patent No. is the patent of 200920311055.9 " a kind of gear shift pencil sharpeners ", above-mentioned deficiency is revised, its patent is with regulating the guiding mechanism that hinders pen axle axial location, adjust the distance of resistance pen axle and working chamber, realize the purpose of cutting different thicknesses nib, resistance pen axle gos deep into working chamber more, and the nib of cutting out is thick more, otherwise thin more.Though this patent has solved the thickness problem of nib, the tapering of nib does not change, and the thick more nib that it cuts out of nib that exists the system of cutting is short more, does not have to solve the deficiency of the very fast chap of nib when writing, and has reduced writing time on the contrary.This complex structure, cost height.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of pencil sharpener New Kind of Hob.This patent realizes cutting the purpose of system nib thickness by the size that changes pencil sharpener hobboing cutter one end toper cutter hub angle.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of pencil sharpener New Kind of Hob, comprise the hobboing cutter that has axis hole that is arranged in the body, the outer surface of described hobboing cutter is provided with many spiral-shaped blades that are connected as a single entity with it, integral body is cylindrical, end at hobboing cutter is provided with gear, it is characterized in that: the end that described hobboing cutter is connected with gear is taper.
Characteristics of the present utility model are: with the pencil of this hobboing cutter cutting, lead for retractable pencil tapering appropriateness, chap, not easily broken point are grown, are difficult for to the lead for retractable pencil that the nib place has one section diameter to equate substantially, writing time; Simple in structure, cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is installed in structural representation in the pencil sharpener for the utility model.
The specific embodiment
Shown in Fig. 1,2, the pencil sharpener New Kind of Hob comprises the hobboing cutter that has axis hole 1 that is arranged in the body, and the outer surface of hobboing cutter 1 is provided with many spiral-shaped blades that are connected as a single entity with it, and integral body is cylindrical, is provided with gear 2 at an end of hobboing cutter 1.The end that hobboing cutter 1 is connected with gear 2 is taper 1-1.Taper 1-1 face on the hobboing cutter 1 and cylindrical surface are 0.1 °～10 ° angles, and the spiral-shaped blade on the hobboing cutter 1 becomes streamlined with spiral-shaped blade on the taper 1-1 face and is connected.The length of hobboing cutter 1 upper conical 1-1 part is 1～10mm.
Hobboing cutter is in actual manufacture process, and the nib thickness adjustment of cutting system is to realize by taper 1-1 face and the cylindrical surface angle adjusted on the hobboing cutter 1.The requirement nib is thin, and then angle is little, requires nib thick, and then angle is big.
It makes principle: the taper 1-1 part length on the hobboing cutter 1 determines the nib leading portion diameter after the system of cutting to equate the length of lead for retractable pencil substantially, taper 1-1 on the hobboing cutter 1 is partly long, the nib leading portion diameter of then cutting system equates that substantially lead for retractable pencil is longer, otherwise, then shorter, rationally control the length of taper 1-1 part according to the requirement of cutting system nib thickness, so that the nib of cutting after the system obtains long writing time and enough mechanical strengths.
