Description

Pencil helps cuts device

The utility model relates to pencil cutting technology field, and particularly pencil helps turning device.

At present, the used pencil of primary grades and child is the desirable hard-tipped pen of writing, drawing, and the pencil cutter material has rotary pencil-knife and single blade pocket knife.Rotary pencil-knife is the frangibility pencil-lead in use, and the nib of cutting out too the point influence writing quality, its use value is descended greatly; Single blade pocket knife sharpens a pencil, and to bore the writing of indictments, appeals, etc. extensively practical, still,, can not hold well because children's age is little, a dark cutter, a shallow cutter with pencil sharper get concavo-convex differ uncomfortable when using.Easily cut brokenly finger, perhaps that pencil sharper is bad, because these shortcomings of single blade pocket knife, so the students of the junior years seldom use it, but also do not have pencil-knife to help turning device in the market.

The purpose of this utility model will provide a kind of and match with single blade pocket knife; The pencil cutting servicing unit that primary grades and child are safe in utilization, simple in structure.

The utility model adopts following technical scheme to realize above-mentioned purpose: can overlap in the above with one, the garden tube that is used for grasping pencil and pencil can freely be rotated within it helps the body of cutting device as pencil, this body one end is a circular cavity, the other end has a tapered slope, and a hole that is used for solid pressure and Propelling pencil with sharpener in cap is being set near this end place.

Above-mentioned on body near the hole of tapered slope breach end, can be square, rectangle, rhombus, circle and ellipse garden shape.

Help the awl height of the tapered slope gap of cutting device one end to be advisable with the awl height of having cut pencil.

Pencil described in the utility model helps cuts device, simple in structure, easy to manufacture, can adopt metal or injection moulding one-shot forming, and cost is low, during use, be difficult for cutting brokenly finger, the lead for retractable pencil that fractures, each cutting output can be controlled, children easily grasp, and have easily cut pencil, are single cutting tool auxiliary implements preferably.

Introduce the utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the vertical view of an embodiment of the utility model.

As shown in Figure 1 and Figure 2, pencil shown in this example helps cuts device, its body 1 is a garden tube, it can be metal, also can one-shot forming, length is shorter than pencil, can hold with hand and to be advisable, internal diameter is more bigger than pencil diameter, and pencil inserts from garden shape cavity 5 ends, stretches out a part at breach 3 places of tapered slope, on body 1, there are shape hole, an ellipse garden 2, thumb can be from the hole 2 to push or rotation pencil near the tapered slope end, breach 3 can be controlled the amount of cutting of every cutter well, therefore, has avoided effectively cutting bad pencil and having guaranteed safety.
