[0040] Working principle: Before the actual test, the staff can use any of the clamping mechanisms provided in Examples 1-3 to fix the handle of the pot to be tested. The pot is filled with filler with a weight of L×1.5. The pot handle is hung or clamped and fixed on the clamping mechanism. The lifting drive component drives the lifting seat component to drive the clamping mechanism to slide and lift back and forth. During this process, when the pot is lowered, the bottom of the pot will touch the top surface of the machine body and apply pressure to the pot handle until the pot handle breaks and the pot falls onto the rubber plate. The drop detector senses the pot falling and feeds back to the control console in real time. The control console can then issue a command to stop the test and issue a prompt sound to remind the staff to check and archive the test data.
