    摘要： A utility knife that includes a main body, a blade holder assembly movably mounted within the body and a manually engageable member slidably mounted on the main body. The blade holder assembly is constructed and arranged to mount a blade within the main body. The blade holder is movable between a retracted position wherein the blade is disposed within the main body and an extended position wherein the blade protrudes outwardly from the main body to enable a cutting operation. The manually engageable member is operatively connected with the blade holder assembly and is movable to move the blade holder assembly between its extended and retracted positions. The utility knife further includes a blade storage member pivotally connected with the main body. The blade storage member is constructed and arranged to carry a supply of spare blades and is movable between a closed position wherein the spare blades are concealed and a fully opened position permitting access to the spare blades. The utility knife also includes releasable locking structure that is constructed and arranged to releasably lock the blade storage member in its closed position. Interengaging structure is provided between the blade storage member and the main body to prevent movement of the blade storage member from the closed position to the fully opened position under the force of gravity when the locking structure is released to unlock the blade storage member from the closed position.

    摘要翻译： 一种实用刀，包括主体，可移动地安装在主体内的刀片保持器组件和可滑动地安装在主体上的可手动接合构件。 叶片保持器组件被构造和布置成将叶片安装在主体内。 刀片保持器可在其中刀片设置在主体内的缩回位置和延伸位置之间移动，其中刀片从主体向外突出以实现切割操作。 可手动接合的构件与刀片保持器组件可操作地连接并且可移动以使刀片保持器组件在其延伸位置和缩回位置之间移动。 实用刀还包括与主体枢转连接的刀片存储构件。 叶片存储构件被构造和布置成承载备用叶片的供应，并且可在隐藏备用叶片的关闭位置和允许进入备用叶片的完全打开位置之间移动。 实用刀还包括可释放的锁定结构，其被构造和布置成将刀片存储构件可释放地锁定在其关闭位置。 在叶片存储构件和主体之间设置有内部结构，以防止当锁定结构被释放时刀片存储构件在重力作用下从关闭位置移动到完全打开位置，以将刀片存储构件从关闭状态 位置。
