[0002] In the process of producing trolley cases, hardboard is usually used as the supporting structure of the case to enhance the stability and durability of the case. In order to ensure the production quality of trolley cases, these hardboards will be subjected to impact resistance tests. This test is designed to evaluate the resistance of the hardboard when subjected to external impact or pressure to determine whether it can withstand various impacts and pressures in actual use and protect the safety of the items in the case. At this time, an impact resistance test device will be used.
