Description

Technical Field

[0001] This invention relates to the field of school supplies technology, and in particular to a pencil sharpener. Background Technology

[0002] The common pencil sharpeners in the existing technology are numerous and varied in shape, but they all have a common drawback: they are all single-hole structures with a single shape. Therefore, the pencils sharpened can only be sharpened into one shape, and their function is limited. In order to make up for the shortcomings of the existing technology, a new pencil sharpener needs to be designed to replace it. Summary of the Invention

[0003] In view of this, in order to solve the above problems, the present invention proposes a pencil sharpener, including a cutting disc, an upper shell and a lower shell. The cutting disc is disposed between the upper shell and the lower shell. The lower shell has a plurality of embedded protrusions, which pass through through holes in the cutting disc and connect to the upper shell. The side wall of the upper shell has a plurality of upper half peeling hole grooves, and the side wall of the lower shell has a plurality of lower half peeling hole grooves. The upper half peeling hole grooves and the lower half peeling hole grooves are combined in a one-to-one correspondence to form a plurality of pencil placement holes. The cutting disc has a plurality of blades of different shapes, each blade can sharpen pencils of different shapes, and each blade corresponds to a pencil placement hole.

[0004] Furthermore, the cutter head has bolt holes, through which bolts pass to connect to the lower housing for fixing the cutter head.

[0005] Furthermore, the upper shell has multiple shaving holes to allow pencil shavings to come out.

[0006] Furthermore, the upper shell, cutter head, and lower shell have the same shape.

[0007] Furthermore, the upper shell, cutter head, and lower shell are circular.

[0008] Furthermore, the upper shell, the blade disc, and the lower shell are square or polygonal in shape.

[0009] Furthermore, the upper and lower shells are made of one of the following materials: wood, plastic, or rubber.

[0010] The above technical solution has the following beneficial effects:

[0011] The cutting disc of this invention is equipped with multiple cutting heads of different shapes. Depending on the user's preferences and usage scenarios, one end of the pencil can be placed in the pencil placement hole, and various shapes of pencil tips can be sharpened as needed. The blade is composed of multiple cutting heads of different shapes combined into a whole integrated cutting disc, which has a simple structure, multiple functions, and meets people's needs for sharpening pencils.

[0018] The invention will now be further described with reference to the accompanying drawings.

[0019] Example 1: The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, a pencil sharpener includes a blade disc 2, an upper shell 1, and a lower shell 3. The blade disc 2 is located between the upper shell 1 and the lower shell 3. The lower shell 3 has multiple embedded protrusions 31, which pass through through holes 21 on the blade disc 2 and connect to the upper shell 1. The side wall of the upper shell 1 has multiple upper half-peeling slots 11, and the side wall of the lower shell 3 has multiple lower half-peeling slots 32. The upper half-peeling slots 11 and lower half-peeling slots 32 are combined one-to-one to form multiple pencil placement holes 4. The blade disc 2 has multiple blades 22 of different shapes, each blade 22 can sharpen pencils of different shapes, and each blade 22 corresponds to one pencil placement hole 4.

[0021] In this embodiment, the cutter head 2 has bolt holes 23, through which bolts pass and connect to the lower shell 3 for fixing the cutter head 2. The upper shell 1 has multiple shaving holes 12 to allow pencil shavings to exit. The upper shell 1, cutter head 2, and lower shell 3 are identical in shape and are circular. In this embodiment, the upper shell 1 and lower shell 3 are made of wood.
