Abstract: Electric kettles have the advantages of fast heating speed, good insulation effect, and multiple styles. People often use electric kettles in their daily lives, but there have also been cases where the structure of the kettle fails during use. In response to the situation where the handle of a certain electric kettle fell off during use, through screw detection and mechanical analysis, the reasons for the handle falling off were found to be: the length of the screw fixing the handle was too short, the screw hole of the lower bending section of the steel plate connecting the handle was too large, and the length of the upper bending section of the steel plate connecting the kettle body and the handle was too short. The upper bending section of the steel plate was fixed by inserting it into the handle's inclined slot, causing the handle to fall off. The obtained results can provide reference for the design of hot water kettle handles.
