Abstract

The utility model discloses a pencil sharpener in a palm. The utility model is composed of a pencil sharpening hole 2, an upper cover 1 for a pencil sharpening hole 13 and a base 8, wherein, the pencil sharpening hole 2 and the upper cover 1 for a pencil sharpening hole 13 are arranged on the top of the utility model, and vertical tooth posts 6 for spiral cutters are fixedly installed on the center of the bottom of the base 8. The pencil sharpener in a palm which adopts the structure overcomes shortcomings that the operation of manually sharpening a pencil is unsafe, time consuming and laborious, efficiency is low, and chips are scattered; at the same time, the utility model solves the disadvantages that the service life of a common pencil sharpener is short, the common pencil sharpener can not sharpen a thick lead core of a propelling pencil, etc. The utility model not only can sharpen a common wooden pencil, but also can sharpen the lead core of the propelling pencil; the utility model is suitable for satisfying the requirements of different thickness, and has the advantages of safe and convenient use, favorable quality in sharpening the pencil, chip collection and storage and cleanness and sanitation.

Description

The palm pencil sharpener

The utility model relates to a kind of the pen or shape tool of cutting, particularly a kind of palm pencil sharpener.

At present, engineers and technicians and large, medium and small student are in the process of painting, draw or writing, generally use pencil to make writing implement, pencil must can use after the system of cutting, for different pencils that use occasion requires to cut the processing procedure degree different, people adopt blade to cut the system pencil generally speaking, and primary and secondary students are then many to cut the system Wood pencil or with the little lead for retractable pencil propelling pencil that need not cut with pencil sharpener.Cut then time-consuming, the effort of system with blade, efficient is low, and the scrap under cutting is scattered influences environmental sanitation, scratches finger easily because of sharp blade simultaneously, uses dangerous; The easy passivation of the blade of pencil sharpener, service life is short, has have more than is neededly just scrapped several times, and easily pencil-lead has been revolved disconnected; Though the minor diameter pencil does not need to cut pen, the lead for retractable pencil intensity difference very easily fractures, and the major diameter pencil does not hold size not meet the drawing requirement, is not suitable for to draw drawing usefulness, and it also needs the special system of cutting instrument.

The purpose of this utility model is to provide a kind of can cut the palm pencil sharpener that the general Wood pencil of system can be cut the system propelling pencil refill again.

The purpose of this utility model is achieved in that it comprises loam cake 1 and base 8, cutter tooth post 6 is packed in the waist of cutter tooth axis of a cylinder 9, loam cake 1 is sleeved in the ring-shaped step 3 of base 8 circular opens upper end, the waist of loam cake 1 is provided with the annular snap ring 4 of projection, snap ring 4 is provided with a breach, the top of loam cake 1 is provided with cuts a hole 2, cut a hole 13, the middle part, lower end of loam cake 1 is provided with cutter tooth axis of a cylinder jack 11, the inwall of the annular breach 3 on base 8 tops is provided with card lid projection 12, the bottom of base 8 is provided with cutter tooth socket for post 7, the lower end of cutter tooth axis of a cylinder 9 is packed in the cutter tooth socket for post 7 of base 8 bottoms, and the upper end of cutter tooth axis of a cylinder 9 is sleeved in the cutter tooth axis of a cylinder jack 11 of loam cake 1.Cutting a hole 2 is cylindrical hole with the upper end of cutting a hole 13, and following waist is a conical bore, cuts the semicircle taper hole 5 that close cutter tooth post 6 sides in 2 bottoms, a hole have opening, cuts there is opening 13 bottoms, a hole near cutter tooth post 6 sides semicircle taper hole 10.The cylinder outer wall of cutter tooth post 6 is spiral oblique cutter tooth.The top of loam cake 1 is provided with propelling pencil knockout length control hole 14 and 15.Be provided with reinforcement between the internal perisporium of the outer wall of cutter tooth socket for post 7 and base 8.

The utility model has the advantages that: it overcome the blade hand sharpen a pencil dangerous, waste time and energy, efficient is low, scrap is scattered shortcoming, solve pencil sharpener life-span weak point simultaneously and can not cut deficiencies such as making propelling pencil lead bullion core, it both can cut the general Wood pencil of system, can cut the pen core of system propelling pencil again, and be suitable for the requirement of various different thicknesses, it is safe in utilization, convenient, cut that a quality is good, the storage of scrap collection, sanitation and hygiene.

The utility model is described in further detail below in conjunction with drawings and Examples.
