AI Technical Summary
Existing knife packaging boxes have assembly gaps when transporting irregularly shaped knives, which can cause the knives to move axially and collide radially under the vibration or impact of transportation or drops. This can result in minor issues such as edge wear or, in severe cases, knife body breakage.
The structure employs elastic memory foam and dynamic abutment rods. The elastic memory foam fills the contact surface between the tool and the box to absorb transportation vibrations, and the sliding of the abutment rod and linkage rod adaptively conforms to the tool profile, eliminating rigid gaps and forming a buffer layer to maintain the tool in a zero-displacement state.
It effectively avoids edge damage caused by movement, ensures the stability and reusability of the tool during transportation, and prevents edge wear and breakage.
