Description

Technical Field

[0001] This utility model relates to the field of material cutting device technology, specifically to a cutting device and a cutting machine. Background Technology

[0002] When using sheet materials such as KT board, it is necessary to cut grooves at certain angles to facilitate folding and forming different shapes, such as prisms. It is also necessary to cut at specific locations to produce different sizes. Chinese patent document CN217372617U discloses a sheet material grooving tool, including a top cover, a main body, and an adjusting block. A blade clamping block presses the blade firmly against the bottom of the housing. A limiting groove on the blade, in conjunction with a limiting protrusion in the blade groove, adjusts the length of the blade extension. Adjusting blocks of different depths limit the cutting depth of the blade.

[0003] However, existing grooving tools can only perform grooving functions and cannot meet the needs of cutting materials into different sizes. Moreover, existing grooving tools cannot ensure the accuracy of the grooving position and require auxiliary tools, making the operation relatively complicated. Utility Model Content
