Zusammenfassung:	The application discloses a top cover assembly and a battery. The top cover assembly includes a cover plate, a pressing plate and a pole. The cover plate is provided with a first through-hole. The pressing plate includes a first end surface and a second end surface oppositely arranged, and a variable-section through-hole. The pole sequentially passes through the first through-hole and the variable-section through-hole, and the first end surface faces the cover plate. An opening area of an end of the variable-section through-hole toward the first end surface is al, an opening area of another end of the variable-section through-hole toward the second end surface is a2, and a cross-sectional area of the pole is A, where a1, a2 and A satisfy with: a2≤A
