Abstract

Embodiments of the present application provide a sleeve assembly, a cover plate assembly, a battery, and an electricity-consuming apparatus. The sleeve assembly is used for sealing a through hole. The sleeve assembly includes: a sleeve with an opening on at least one end; a nail body including a body portion. The size of the body portion is larger than the size of the barrel diameter of the sleeve. The body portion is configured to be inserted into the sleeve through the opening and press the inner wall of the sleeve after the sleeve is inserted into the through hole in the axial direction so as to form a protrusion for riveting the sleeve to the through hole on the outer wall of the sleeve.
