The appropriate thickness of the tool tip can ensure the accuracy and controllability of the cut during cutting, avoiding unnecessary breakage. In the above embodiment, the material of the tool tip body 1 is formed by processing SKD11 or DC53 after quenching. The processing is formed by wire cutting or bending.

[0035] In this embodiment, through the U shape of the tool tip body 1, the design of the inclined surface of the cutting edge 11 and the appropriate thickness dimension, the technical effects of no edge breakage and no breakage during the grooving of the corrugated cardboard box are achieved. This tool tip design can ensure accurate and stable cutting of the cardboard box during the cutting process, maximizing the protection of the integrity and service life of the corrugated cardboard box.

[0036] Both sides of the tool tip body 1 are provided with fitting parts 12, and chamfers 121 are arranged on the inner sides of the fitting parts 12.
