    • A retractable tool bit assembly utilized in connection with a robotic gripper type end-effector. The apparatus includes one or more spring loaded nestable or telescoping tubular sections (32,34) together with a catch mechanism for capturing and holding the tool, such as an allen key, in its retracted position. The innermost tubular section includes a threshold cap and engages and holds the tool (36). The catch mechanism consists of a slider type mechanism located adjacent a relatively large router base section and includes means for engaging a conically or mushroom shaped rear end portion (76) of the tool when the telescoping sections are moved to a retracted or parked position. The catch mechanism is released upon actuation of a rotary tool drive motor coupled to a circular mount and which holds the base section. When released all the telescoping sections including the tool extends fully outward to a use position.
    • 结合机器人抓爪式末端执行器使用的伸缩工具组件。 该装置包括一个或多个弹簧加载的可嵌套或伸缩管状部分(32,34),以及用于在其缩回位置捕获和保持诸如内六角扳手的工具的捕捉机构。 最内管状部分包括阈值帽并接合并保持工具(36)。 捕获机构包括位于相对大的路由器基部附近的滑块型机构,并且包括当伸缩部分移动到缩回或停放位置时用于接合工具的圆锥形或蘑菇状后端部分(76)的装置。 在联接到圆形安装座的旋转工具驱动电动机的致动下,锁定机构释放并保持基部。 当释放时,包括工具的所有伸缩部分完全向外延伸到使用位置。
