Description

Changing knife frame device

Technical field:

The utility model relates to pencil sharpener accessory technical field, is specifically related to a kind of knife rest (cutter core) more changing device of electric pencil-sharpening unit.

Background technology:

The existing students in middle and primary schools of China about 1.9 hundred million people, university students and middle school students about 4,000 ten thousand people, adult student at school about 5,000,000 people, enterprises and institutions leader about 3,400 ten thousand people.The demand for development of society strengthens national literature education quality further, and educational investment significantly increases, and stationery industry has very wide consumption market.And the pencil sharpener market in stationery industry also exists huge business opportunity especially.

As everyone knows, what present lower pupil used is all pencil, and pencil often needs to cut, and concerning child, it is more unsafe for using pocket knife to sharpen a pencil, and a lot of child is through being everlasting with the finger hurting oneself during pocket knife.Nowadays a lot of head of a family buys not only good-looking, a but also handy pencil sharpener can to the child of oneself, and wherein the feature such as electric pencil-sharpening unit, good looking appearance easy to use, safe with it wins liking of people.

Cutter core in current electric pencil-sharpening unit on the market and main body are fixed together, and after using a period of time, old cutter core all can produce wearing and tearing in various degree, affects result of use, and cause pencil sharpener cannot continue to use, service life is shorter.After cutter core cannot use, whole electric pencil-sharpening unit all becomes useless refuse, wastes energy, and increasing family's expenditure, the more important thing is without being beneficial to energy-conserving and environment-protective.

Utility model content:

The purpose of this utility model is to provide a kind of changing knife frame device, and its design operation is simple and easy, the old cutter core of wearing and tearing after using can be replaced, brand-new cutter core be reloaded, easy to learnly easily to change, easy to use, extends the service life of pencil sharpener.

In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it comprise slip cap spring, immovable support enter a slip cap, interior structural support, knife rest and cutter core, what the upper end, side of interior structural support can slide up and down to be provided with immovable support enters a slip cap, a slip cap upper end of entering for immovable support is socketed with slip cap spring, is removably provided with knife rest and cutter core between the gear grooved entering bottom a slip cap lower end and interior structural support of immovable support.

Principle of the present utility model is: what knife rest and cutter core were arranged on immovable support enters between slip cap and interior structural support, and upwardly a slip cap that enters of immovable support puts in place and can take out old, discarded knife rest and cutter core; After new knife rest and cutter core being in place, the slip cap that enters putting down immovable support makes it appliance for releasing single and replys position, and what make knife rest and cutter core firmly be arranged on immovable support enters between slip cap and interior structural support.

The utility model handled easily, practicality is high, thus substantially prolongs the service life of electric pencil-sharpening unit, promotes pencil cutting result of use, very environmental protection and energy saving.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model,

Fig. 2 be in the utility model immovable support enter the schematic diagram that a slip cap upwards promotes,

Fig. 3 is the schematic diagram taking out knife rest and cutter core in the utility model;

Reference numeral: A-slip cap spring, B-immovable support enter a slip cap C-, interior structural support, D-knife rest and cutter core.

Detailed description of the invention:

Below in conjunction with accompanying drawing, the utility model is described in detail.

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that detailed description of the invention described herein only in order to explain the utility model, and be not used in restriction the utility model.

With reference to Fig. 1, this detailed description of the invention is by the following technical solutions: it comprise slip cap spring A, immovable support enter a slip cap B, interior structural support C, knife rest and cutter core D, what the upper end, side of interior structural support C can slide up and down to be provided with immovable support enters a slip cap B, a slip cap B upper end of entering for immovable support is socketed with slip cap spring A, is removably provided with knife rest and cutter core D between the gear grooved entering bottom a slip cap B lower end and interior structural support C of immovable support.

Using method with reference to this detailed description of the invention of Fig. 2-Fig. 3 is:

Replace the old knife rest after wearing and tearing (cutter core) step:

Refer to that a slip cap B that enters for upwardly immovable support puts in place with left hand, now knife rest and cutter core D had living space completely can shift out immovable support enter outside a slip cap B, just refer to pinch knife rest with the right hand and cutter core D directly shifts out in gear grooved.

(also can pinch knife rest and cutter core D with thumb and forefinger, simultaneously upwardly immovable support enter a slip cap B, directly can shift out knife rest and cutter core D outward after cross holddown groove departs from gear completely bottom put in place back tool rest and cutter core D).

Reload brand-new knife rest (cutter core) step:

Refer to that a slip cap B that enters for upwardly immovable support puts in place with left hand, now have living space completely and can fill knife rest and cutter core D, just refer to pinch entering in a slip cap B of new knife rest and the direct shift-in immovable support of cutter core D with the right hand, then the cross recess of bottom is filled in corresponding gear holddown groove.

(what also can pinch that knife rest and cutter core D directly first fill in immovable support with thumb and forefinger to enter in a slip cap B upwardly simultaneously, after putting in place, cross holddown groove bottom new knife rest and cutter core D is filled in corresponding gear holddown groove).

This detailed description of the invention handled easily, practicality is high, thus substantially prolongs the service life of electric pencil-sharpening unit, promotes pencil cutting result of use, very environmental protection and energy saving.

The above is only in order to illustrate the technical solution of the utility model and unrestricted, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
