Description

Technical Field

[0001] The utility model relates to the technical field of common cutting tools, in particular to an art knife. Background Art

[0002] A utility knife, also commonly known as a carving knife or wallpaper knife, is a commonly used knife in industry and life, art and handicraft making. It is also commonly used in students' stationery and is mainly used to cut soft objects. It is generally composed of a protective shell and a blade. The blade has an oblique edge and usually adopts a push-pull structure to push the blade out or retract it into the protective shell. However, existing utility knives usually use a wavy slot to squeeze and fix the blade. Although this method is flexible, it does not provide high stability for fixing the blade. The blade shakes greatly during use, and when the tip of the knife is pressed against the object to cut, the blade easily retracts into the handle under pressure, which is inconvenient to use.
