The invention discloses a buckle assembly, a glass panel fixing structure for an extractor hood and the extractor hood. The buckle assembly comprises a base and an elastic sheet; a through hole penetrating through the base in the thickness direction is formed in the base; and at least one part of the elastic sheet is suitable for penetrating through the through hole from front to back to be connected with the base. According to the buckle assembly, the elastic sheet can generate a certain elastic deformation, the position can be fine-adjusted, and therefore the assembling precision can be improved.
