Abstract

A pencil sharpener relates to an auxiliary device for writing tools, which comprises a base and 4-8 cutting blades, wherein cutting edges of the cutting blades are combined at one end, and the other ends of the cutting edges of the cutting blades are upwardly stretched along a pen holder. Compared with the prior art, the pencil sharpener is extremely simple and safe in operation and extremely convenient and fast in use, is not easy to break off pencil leads and is extremely adaptable to sharpening thick lead cores.

Description

The pencil sharpening apparatus

Technical field

The utility model relates to the writing appliance servicing unit, and especially a kind of lead for retractable pencil that is used for sharpening a pencil makes it become conical pencil sharpening apparatus.

Background technology

In the past, be used for sharpening a pencil nothing more than being exactly to be pencil-knife and single-edge blade, the structure of pencil-knife mostly is that a base is arranged, a circle arranged on the base with the similar groove of pencil cross-sectional diameter size, a side is screwed the blade of a blade towards notch on the groove, such pencil-knife can only be used for cutting Wood-bar pencil, for cutting the unusual difficulty of pencil that is not rod, as easy as rolling off a logly breaks lead for retractable pencil and cuts bad penholder; And single-edge blade to be exactly one side be blade, another side is surrounded by the protection piece, sharpens a pencil or pen core the time; to hold penholder on the other hand, hold blade on the other hand, though can cut pen core; if but the careless as easy as rolling off a log finger that cuts therefore use also inconvenience, and speed is also slow.

Summary of the invention

The utility model provides a kind of pencil sharpening apparatus, mainly solves the prior art problem that lead for retractable pencil is cut off easily and cutting speed is slow when cutting lead for retractable pencil.

In order to address the above problem, the technical scheme that the utility model adopted is: it includes base and blade, and described blade has 4～8, and blade one end of these blades is got together, and the other end is axially gone up along penholder and launched.

The end that above-mentioned blade is got together can place on the described base, and this base can be cylindrical body, and this cylindrical body can be located at circular being used for and collect in the collection box of the fallen lead for retractable pencil powder in gap between blade and the blade.

Owing to adopted technique scheme, the utility model compared with prior art, the beneficial effect that has is: because blade one end of these blades is got together, the other end is axially gone up along penholder and is launched, therefore surround a taper cutting space that the pinnacle is downward, therefore, in the time of cutting lead for retractable pencil, only need hand to hold penholder, lead for retractable pencil put into changes several circles in the taper cutting space, lead for retractable pencil has just become the taper shape wanted, operates very simple and safe, very easy to use quick, and lead for retractable pencil is not allowed easily broken.

Description of drawings

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

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is that the utility model is at the structural representation of cutting under the state of pen core.

Fig. 4 is the structural representation of the utility model cover lid.

The specific embodiment

Below in conjunction with the accompanying drawing example, the utility model is described in further detail:

As depicted in figs. 1 and 2, it includes base 2 and blade 1 the utility model, blade 1 has 6, blade one end of these blades is got together, the other end is axially gone up along penholder and is launched, blade surrounds a taper cutting space 3 that the pinnacle is downward, the end that these blades are got together places on the base 2, this base is a cylindrical body, this cylindrical body is located in the circular collection box 5, this collection box is used for collecting from the fallen lead for retractable pencil powder in the gap between blade and the blade, on this collection box also by the lid 6 that has been threaded.

In the time will cutting pen core 4, earlier the lid 6 of sharpening apparatus is outwarded winding, hand is taken penholder 7 then, pen core 4 is put into the cone space 3 of sharpening apparatus, rotation penholder 7, pen core 4 promptly turns on each blade, and blade is pruned the unnecessary part of pen core, and pen core can form the taper shape that people want, very simple of operation, convenient, fast, the lead for retractable pencil powder of cutting out hangs down from the cutter seam of each blade, falls in collecting box, after using, outwell and get final product collecting lead powder in the box, clear up also very conveniently, give to collect the lid upper cover then, just can carry.
