    • A lock release mechanism for a folding combination tool having a plurality of supplemental tools (e.g., a knife, screwdriver, can opener, etc.) mounted at the free end of a generally U-shaped handle for rotation from a storage position within the handle to an extended “in use” position outside the handle. The locking mechanism is characterized by a leaf spring formed at the free end of the handle that lockingly engages the mounting end or shank of one or more of the supplemental tools when such tool is rotated from the handle to its fully extended position for use. The lock release mechanism preferably includes a bulge, formed on a different supplemental tool, that extends outside the handle so that the bulge may be depressed into the handle by a user. The mounting end of the different supplemental tool includes a leading edge portion that, when the bulge is depressed, moves the leaf spring out of engagement with the mounting end of the locked tool so that the latter is released and may be rotated by the user back into the handle.
    • 一种用于折叠组合工具的锁定释放机构,其具有安装在大致U形手柄的自由端处的多个辅助工具(例如,刀,螺丝刀,开罐器等),用于从手柄内的存储位置旋转 到手柄外的一个扩展的“使用中”位置。 锁定机构的特征在于,当这种工具从手柄旋转到其完全伸出位置以便使用时,形成在手柄的自由端处的片簧与一个或多个补充工具的安装端或柄锁定地接合。 锁定释放机构优选地包括形成在不同的辅助工具上的凸起,其延伸到手柄外部,使得凸起可以由使用者压入手柄。 不同补充工具的安装端包括前缘部分,当凸起被压下时,前缘部分使片簧与锁定工具的安装端部脱离接合,使得后者被释放,并且可以由用户回转 进入手柄。
