Abstract
The invention discloses a pencil sharpener which comprises a sharpener handle (1) and a sharpener body (2). A pencil point grinding mechanism (3) is arranged at the tail end of the sharpener handle (1), at least two conical holes (4) with different sizes are formed in the tail end of the pencil point grinding mechanism (3), and abrasive layers are arranged on the surfaces of the conical holes (4). The pencil sharpener can sharpen a pencil point, and cracking of a pencil lead is avoided while the pencil lead is sharpened.
Description
Technical field
The present invention relates to a kind of stationery, especially relate to a kind of pencil-knife.
Background technology
People can ream the wood layer of pencil outside with pencil-knife, but for inner lead for retractable pencil, a lot of people are difficult to fine away, and even in the process of cutting lead for retractable pencil, lead for retractable pencil can be cut disconnected.
Summary of the invention
In order to solve, current lead for retractable pencil is difficult fines away in the present invention, even can be cut disconnected problem, a kind of pencil-knife is provided for this reason, comprise handle of a knife 1 and cutter hub 2, the end of described handle of a knife 1 is provided with nib grinding mechanism 3, the end of described nib grinding mechanism 3 is provided with at least two bellmouths 4 that size is different, and the surface of bellmouth 4 is provided with frosted layer.
Pencil-knife of the present invention, the end of described nib grinding mechanism 3 is provided with three bellmouths 4 that size is different, and bellmouth 4 aperture reduce successively from top to bottom.
The invention has the beneficial effects as follows:
The present invention is after lead for retractable pencil is cut out, only need to be placed in the bellmouth of corresponding size, because hole is taper, therefore interior as long as lead for retractable pencil can be filled in bellmouth, Propelling pencil with sharpener in cap or pencil-knife again, just the front end of lead for retractable pencil can be worn into point, in sharpening lead for retractable pencil, also avoid the situation of lead for retractable pencil fracture to occur.
Brief description of the drawings
