Description

technical field [0001] The invention relates to the field of pencil cutting stationery, in particular to a novel integrated hob structure for a pencil sharpener. Background technique [0002] There are two types of pencil sharpeners commonly used at present. The first type is a single-edged pencil sharpener. The thin blade is directly fastened on the knife holder with bolts or screws, and the flaky pen scraps are planed out by the rotation of the pencil. Its structure is simple. , but the blade is easy to blunt, the service life is short, the nib is easy to break, and the cutting quality drops quickly; the second type is the spiral hob pencil sharpener, which uses the hob installed on the hob to rotate around the axis, and the cutting is fixed on the hob The pencil in the center of the holder can be scraped out of flakes, which is easy to cut and has a long service life. [0003] Existing hob structures such as figure 1 Shown: A through hole 03 is machined in the center of...
