Description

Technical Field

[0001] This utility model relates to the technical field of stationery products, and in particular to a pencil sharpener. Background Technology

[0002] Traditional pencils and other sharpening pencils consist of a lead and a wooden casing. When sharpening a pencil with a pencil sharpener, the lead and wooden casing can usually only be cut along the taper of the sharpener. The exposed part of the lead cannot be cut separately from the wooden casing; the wooden casing must be cut along with the exposed lead. When a certain pencil tip length is required, the sharpener can only continuously cut the lead, eventually leading to the lead being over-sharpened, affecting its use in certain situations (art pens, eraser pens, etc.).

[0003] In view of this, the inventor of this case conducted in-depth research, which led to the creation of this case. Utility Model Content

[0004] The purpose of this invention is to provide a pencil sharpener that can perform rough sharpening.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A pencil sharpener includes a base and a blade. The base has a conical cutting cavity and a pen tip protrusion groove. The conical cutting cavity has a pen body inlet and a pen tip inlet. The pen tip inlet communicates with the pen tip protrusion groove. The blade is correspondingly disposed in the conical cutting cavity.

[0007] Furthermore, the protruding groove of the pen tip forms a stop wall corresponding to the pen tip inlet, and the protruding groove of the pen tip forms a pen tip exposed area between the stop wall and the pen tip inlet.

[0008] Furthermore, the pen tip inlet diameter is 3~4.5mm, the pen body inlet diameter is 6.5~8.5mm, the blade length is 7~9mm, and the pen tip exposed area is 3.5~4.5mm.

[0009] Furthermore, the pen tip inlet diameter is 4.5~6mm, the pen body inlet diameter is 9~11mm, the blade length is 9~11mm, and the exposed pen tip area is 5~6mm.

[0010] Furthermore, the tapered cutting cavity is a conical cavity.

[0011] After adopting the above technical solution, the present invention provides a pencil sharpener with the following beneficial effects: The pencil sharpener of the present invention is suitable for cutting pencils with relatively thick leads, such as eraser pencils. During cutting, when the pencil body is placed in the conical cutting cavity, the blade can cut the wooden outer shell of the pencil, or the wooden outer shell and the lead. When the pencil tip is exposed and can protrude from the tip inlet into the tip protrusion groove, the blade only cuts the pencil body portion located within the conical cutting cavity, while not cutting the lead portion exposed within the tip protrusion groove. This allows the pencil sharpener of the present invention to cut the wooden outer shell while preserving a relatively thick lead, resulting in a pencil tip with a certain usable length and a superior user experience.

[0017] This utility model relates to a pencil sharpener, such as... Figures 1-3 As shown, the device includes a base 1 and a blade 2. The base 1 has a conical cutting cavity 11 and a pen tip protrusion groove 12. The conical cutting cavity 11 has a pen body inlet 13 and a pen tip inlet 14, with the pen tip inlet 13 communicating with the pen tip protrusion groove 12. The blade 2 is correspondingly disposed in the conical cutting cavity 11. The conical cutting cavity 11 is a conical cutting cavity.

[0018] This invention relates to a pencil sharpener, suitable for cutting pencils with relatively thick leads, such as eraser pens and art pens (not limited to eraser pens). During cutting, when the pen body is placed in the conical cutting cavity 11, the blade 2 can cut the wooden outer shell of the pen, or both the wooden outer shell and the lead. When the pen tip is exposed and can protrude from the pen tip inlet 14 into the pen tip protrusion groove 12, the blade 2 only cuts the pen body portion located within the conical cutting cavity 11, while leaving the lead portion exposed within the pen tip protrusion groove 12 uncut. This allows the pencil sharpener to cut the wooden outer shell while preserving a relatively thick lead, resulting in a pen tip with a certain usable length and a superior user experience.

[0019] Specifically, a stop wall 15 is formed in the pen tip protrusion groove 12 corresponding to the pen tip inlet 14, and the pen tip protrusion groove 12 forms a pen tip exposed area H between the stop wall 15 and the pen tip inlet 14. The pen tip exposed area H can be set according to actual needs.

[0020] As a preferred embodiment, the diameter of the pen tip inlet 14 is 3~4.5mm, the diameter of the pen body inlet 13 is 6.5~8.5mm, the length of the blade 2 is 7~9mm, and the exposed pen tip area H is 3.5~4.5mm.

[0021] In one preferred embodiment, the diameter of the pen tip inlet 14 is 4.5~6mm, the diameter of the pen body inlet 13 is 9~11mm, the length of the blade 2 is 9~11mm, and the exposed pen tip area H is 5~6mm.

[0022] The above embodiments and accompanying drawings are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
