The clamping mechanism (100) is provided inside a cavity formed by a rolled edge (210) of the trash can, and comprises elastic protrusion structures (113); and the elastic protrusion structures (113) can apply clamping force to the trash bag once the trash bag has been fitted over an opening of the trash can, thereby effectively securing the trash bag.
