Description

Technical Field

[0001] The utility model belongs to the technical field of cutting tools, in particular to a utility knife. Background Art

[0002] When existing utility knives cut objects or materials such as wood boards and cardboards with equal widths, in order to avoid skewness during cutting, a line is generally drawn on the object in advance according to the required cutting width along the length direction of the object, and then the user holds the utility knife and cuts along the line. However, when the length of the object is long, such as more than 2 meters, it is not easy to draw a line on the object, and it is not easy to cut the object according to the set width, which easily leads to skewness and uneven width of the cut objects or materials, which in turn makes the objects or materials unusable and wastes the objects or materials.

[0003] Therefore, there is an urgent need to improve the existing utility knife. In the present application, the utility knife is improved in structure to make it compatible with the existing measuring tape, thereby achieving equal-width cutting of longer objects or materials.
