Visually, the pencil sharpener is mainly composed of a blade, a fixing device, a摇杆and other parts. The blade is the core part of the pencil sharpener, which is responsible for shaving off the wooden outer layer of the pencil to expose the ink core inside. The fixing device is used to fix the pencil, preventing it from slipping or moving during the sharpening process. The摇杆is the main tool we use to operate the pencil sharpener, and by rotating it, we can easily complete the sharpening work. Secondly, the advantages of the pencil sharpener are: 1. Convenience and efficiency: The use of a pencil sharpener is very simple, requiring only a light shake to complete the sharpening work, greatly saving our time. 2. Keeping the tip sharp: The blade design of the pencil sharpener makes the shaved pencil tip sharper, which helps improve the quality and efficiency of writing. 3. Protecting the pencil: The fixing device of the pencil sharpener can effectively prevent the pencil from slipping or breaking during the sharpening process, protecting the service life of the pencil. Thirdly, how to choose and use a pencil sharpener: 1. Choose a suitable pencil sharpener that meets your needs based on personal preferences and usage habits, such as size, shape, color, etc. 2. Regularly clean and maintain to keep the good performance of the pencil sharpener and remove impurities and residues on the blade.

3. Use correctly by ensuring that the pencil is fixed firmly to avoid slipping or moving during the sharpening process. At the same time, control the force to avoid shaving off too much of the wooden outer layer of the pencil.
