Abstract

The invention relates to a pencil sharpener uneasy to break pencil leads. The pencil sharpener comprises a blade and a tool post, wherein the blade is divided into a shell sharpening blade and a lead sharpening blade; a circular truncated cone-shaped cavity is formed on the shell sharpening blade, a long chip outlet is formed on one side of the cavity, and the blade is mounted on one side of the chip outlet; the pencil lead extends out from a small opening of the circular truncated cone-shaped cavity; and the lead sharpening blade is provided with a conical cavity, a long chip outlet is formed on one side of the cavity, and the blade is mounted on one side of the chip outlet. The pencil sharpener uneasy to break pencil leads, provided by the invention, has the following advantages that: the lead breakage can be effectively prevented during sharpening small pencils; compared with the common pencil sharpener, the pencil sharpener provided by the invention only has cost slightly increased; the lead sharpening blade and the shell sharpening shell are used together; meanwhile, the lead sharpening blade can be combined with the common sharpener, a hand-rocking roller blade type sharpener and a sharpening blade so that convenience can be brought in sharpening the pencil lead and the sharpening frequency can be reduced.

Description

The pencil sharpener that is difficult for the disconnected pencil-lead of volume

Technical field

The present invention relates to the pencil sharpener of the disconnected pencil-lead of a kind of difficult volume.

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, 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, exert oneself to weigh slightly when rolling up, pen core is easily broken.Another kind is a hand drum cutter formula pencil sharpener, becomes an oblique angle to rotate with the hand traverse cylinder knife 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.

Summary of the invention

The objective of the invention is to improve, overcome the shortcoming that it is prone to the disconnected pencil-lead of volume, the disconnected pencil-lead of a kind of difficult volume is provided and the pencil sharpener of the pen core of being convenient to fine away to common pencil sharpener.

The objective of the invention is to realize through following technical scheme:

The pencil sharpener of the disconnected pencil-lead of a kind of difficult volume is made up of blade and knife rest, and blade divides rolling shell cutter and volume core cutter two parts; This volume shell cutter is provided with the truncated cone-shaped cavity, and a side of cavity has a microscler crumb mouth, and blade is installed in one side of crumb mouth, and pen core stretches out from the osculum of truncated cone-shaped cavity; This volume core cutter has a conical cavity, and a side of cavity has a microscler crumb mouth, and blade is installed in one side of crumb mouth.

Beneficial effect of the present invention is: disconnected core in the time of can effectively preventing little pencil; Comparing with common pencil sharpener only increases a spot of cost; Volume core cutter and the supporting use of volume shell cutter, simultaneously, volume core cutter can be used in combination with common pencil sharpener, hand drum cutter formula pencil sharpener and sharpener; Can offer convenience aspect the sharpening pen core, and can reduce and cut a number of times.

Description of drawings

According to accompanying drawing the present invention is done further explain below.

Fig. 1 is the front view of the pencil sharpener of the disconnected pencil-lead of the described difficult volume of the embodiment of the invention;

The specific embodiment

Shown in Fig. 1-6, the pencil sharpener of the disconnected pencil-lead of a kind of difficult volume is made up of blade 6 and knife rest 1, it is characterized in that: 6 fens rolling shells of blade cutter 2 and volume core cutter 8 two parts; This volume shell cutter 2 is provided with truncated cone-shaped cavity 4, and a side of cavity 4 has a microscler crumb mouth 5, and blade 6 is installed in one side of crumb mouth 5, and pen core stretches out from the osculum 4 of truncated cone-shaped cavity; This volume core cutter 8 has a conical cavity 9, and a side of cavity 9 has a microscler crumb mouth 10, and blade 11 is installed in one side of crumb mouth 10.

There is a truncated cone-shaped cavity at volume shell cutter 2 positions of making knife rest 1, knife rest with plastics (or other suitable materials); The open front of this truncated cone-shaped cavity is promptly gone into the size of pen mouth 3 should be able to put into pencil mutually with the pencil body thickness; The size that its rear portion osculum is a knockout mouth 4 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 5, and blade is installed in one side of crumb mouth 5, and the length of blade is only cut and a shell; Do not cut and pen core, blade 6 is generally fixing with screw 7.Pencil is inserted the truncated cone-shaped cavity rotate a shell of just pruning, expose pen core, like Fig. 4, shown in Figure 5 to insert orientation.

There is a conical cavity at volume core cutter 8 positions of knife rest 1; The opening of conical cavity is promptly gone into the size of core mouth 9 should be able to put into pen core mutually with the pen core thickness; This cavity has a microscler breach as crumb mouth 10 towards a side in front; Blade 11 is installed in one side of crumb mouth 10, and blade 11 is generally fixing with screw 12.The pen core that has exposed is inserted conical cavity rotate to insert orientation, it is thin just can the pen core volume to be fined away, like Fig. 4, shown in Figure 6.

Claims
