Abstract

The utility model discloses a multifunctional pencil sharpener for sharpening a pencil. A special core sharpener for sharpening the core of the pencil is additionally arranged on a sharpener bracket of a common pencil sharpener, therefore, when the pencil is blunt, the core of the pencil can be firstly sharpened rather than the whole pencil, and the pencil is not sharpened until that the core of the pencil is completely sharpened, so that the times for sharpening the pencil can be reduced; or a special shell sharpener for sharpening the shell of the pencil is additionally arranged on the basis of the additionally-arranged core sharpener, after the core of the pencil is sharpened, certain shell of the pencil is sharpened by the shell sharpener, the core of the pen is exposed, and the core of the pencil is sharpened by the core sharpener, so that the breaking of the core can be effectively avoided. The pencil sharpener not only has the function of pencil sharpening, but also additionally has the functions of core sharpening and shell sharpening, thereby being more convenient to sharpen the pencil.

Description

Multi-functional pencil sharpener

Technical field

The utility model relates to a kind of stationery of roll cutting pencil, especially relates to a kind of pencil sharpener.

Background technology

Pencil sharpener mainly contains two kinds in the market, and a kind of is common pencil sharpener, is made up of knife rest and blade, and a conical cavity is arranged on the knife rest, and a side of cavity has a microscler breach as the crumb mouth, and blade is installed in one side of crumb mouth.Because pencil is by shell (mainly being cork or coil paper) and the two-layer formation of pen core, the hardness and the toughness of shell and pen core are different, and pen core is hard and crisp, and shell is soft and tough, and both holding capacity are different, and it is heavy slightly to exert oneself when rolling up, and pen core is easily broken.Another kind is a hand drum cutter formula pencil sharpener, becomes an oblique angle to rotate with the hand drum cutter around the pencil that is fixed, and reaches and cuts a purpose, though it has overcome the fraud of easily broken core, volume inconvenience bigger than normal is carried, and price is more expensive.

The design people discloses the pencil sharpener of patent No. ZL200420003416.0, and this technology is divided rolling shell cutter and volume core cutter two parts with common pencil sharpener, overcome the fraud of the easily broken core of common pencil sharpener, but its shortcoming is that the volume pen that a step finishes was divided into for two steps.This patented technology does not put into practice.

The utility model content

Task of the present utility model is that common pencil sharpener is improved, and on the basis of an existing volume function, increases function, can roll up separately cut pen core or separately volume cut a shell.Also can overcome its easily shortcoming of the disconnected pencil-lead of volume, provide the disconnected pencil-lead of a kind of difficult volume or the multi-functional pencil sharpener of the pen core of being convenient to fine away.

The utility model is achieved in that on the knife rest of a common pencil sharpener, set up a volume core pencil sharpener, volume core pencil sharpener is called for short volume core cutter, its function is equivalent to common pencil sharpener rear portion and cuts and the pen core part, it on its knife rest a conical cavity, the size of this cavity and opening thereof is fit to the pencil pen core and enters, and can roll up therein and be whittled into taper shape, so pen core can be fined away.Because the opening of cavity is less, has stopped that the pencil shell enters, and does not cut shell so its blade is not rolled up, its function is to be exclusively used in the sharpening pen core.This offers convenience just for the sharpening pen core, writes the pen core of can fining away earlier when blunt and writes, rolls up pen again up to roll up pen core, can reduce and roll up a number of times.

Perhaps set up a volume shell pencil sharpener on the volume core pencil sharpener basis again setting up.Volume shell pencil sharpener is called for short volume shell cutter, and its function is equivalent to the front portion of common pencil sharpener cuts and housing parts, is a truncated cone-shaped cavity on its knife rest, and the length of its blade is just in time cut and the pencil shell, does not cut and pen core, and pen core stretches out from cavity rear portion osculum.Such pencil sharpener has just possessed three kinds of functions, outside original volume function, volume core sharpening function is arranged again, has also increased volume shell function.Can the same pen of rolling up with usual common pencil sharpener, to have write blunt and fined away with volume core cutter, after pen core roll up, volume was cut some shells or volume pen again, any selection.Can also be earlier with the prune shell of pencil of volume shell cutter, expose pen core, with rolling up the core cutter pen core is fined away then, so just can exert oneself according to the different hardness and the toughness of a shell and pen core, effectively prevent to resolve core.Comparing with common pencil sharpener only increases a spot of cost, can bring a lot of facilities aspect cutting.

The specific embodiment

Attach most importance to second embodiment below and illustrate the specific embodiment of the present utility model in conjunction with the accompanying drawings:

Make knife rest 1 with plastics (or other suitable material), knife rest is provided with a common pencil sharpener 2, and common pencil sharpener is a known technology, need not to specify, Fig. 6 is its volume pen state cutaway view.There is a truncated cone-shaped cavity at volume shell cutter 4 positions of knife rest, the open front of this truncated cone-shaped cavity is promptly gone into the size of pen mouth 5 should be able to put into pencil mutually with the pencil body thickness, the size that its rear portion osculum is a knockout mouth 6 should be able to make pen core stretch out with the pen core thickness mutually, its side towards the front has a microscler breach as crumb mouth 7, blade 8 is installed in one side of crumb mouth 7, the length of blade is only cut and a shell, does not cut and pen core, and blade 8 is general fixing with screw 9.Pencil is inserted the truncated cone-shaped cavity rotate a shell of just pruning, expose pen core, as shown in Figure 7 to knife edge direction.

There is a conical cavity at volume core cutter 3 positions on the knife rest 1, the opening of conical cavity is promptly gone into the size of core mouth 10 should be able to put into pen core mutually with the pen core thickness, this cavity has a microscler breach as crumb mouth 11 towards a side in front, blade 12 is installed in one side of crumb mouth 11, and blade 12 is general fixes (or fix with modes such as powerful viscose glues) with screw 13.Thick blunt pen core is inserted conical cavity rotate to knife edge direction, it is thin just the pen core volume can be fined away, as shown in Figure 8.

Only establish a common pencil sharpener 2 and a volume core cutter 3 on the knife rest 1, just made the multi-functional pencil sharpener of first embodiment.As shown in Figure 1.

Knife rest can be made multiple beautiful or interesting cartoon shape, and the position of pencil sharpener, volume core cutter, volume shell cutter can be according to knife rest shape arbitrary placement.
