An ampoule opener is provided. The ampoule opener has a first case, a second case and a resilient component. The first case has a first lateral wall and a first lower end, the first lower end defines a first lower recess. The second case has a second lateral wall and a second lower end, the second lower end defines a second lower recess, the second recess is opposite to the first recess. The resilient component is situated between the first case and the second case, and the resilient component connects a first connecting edge of the first case and a second connecting edge of the second case. Besides, the resilient component defines a pivot, which enables the first case and the second case to revolve along to pivot, and when the first case and the second case revolve to a closed position, the first lateral wall and the second lateral wall define a capacity space.本發明提供一安瓿瓶開瓶器,包含:一第一殼體、一第二殼體以及一彈性元件。第一殼體具有一第一側壁及一第一下端,第一下端定義一第一下缺口。第二殼體具有一第二側壁及一第二下端,第二下端定義一第二下缺口,第二下缺口與第一下缺口相對。彈性元件位於第一殼體及第二殼體之間,且連接於第一殼體之一第一連接邊及第二殼體之一第二連接邊。其中,彈性元件定義一樞軸,第一殼體及第二殼體以樞軸為轉軸轉動,且當第一殼體及第二殼體轉動至一閉合位置時,第一側壁及第二側壁間可定義一容置空間。1‧‧‧開瓶器100‧‧‧第一殼體101‧‧‧第一連接邊110‧‧‧第一側壁120‧‧‧第一下端121‧‧‧第一下缺口130‧‧‧第一上端140‧‧‧抵掣部200‧‧‧第二殼體201‧‧‧第二連接邊210‧‧‧第二側壁220‧‧‧第二下端221‧‧‧第二下缺口300‧‧‧彈性元件301‧‧‧樞軸400‧‧‧容置空間a‧‧‧穿孔b‧‧‧凹槽
