    Abstract: A tool for securing or removing a cylindrical object by grasping the object and rotating it about its central axis comprises a band clamp assembly and a hinged drive assembly. The band clamp assembly comprises a band clamp which is tightened by means of a thumbscrew or hex nut. The hinged drive assembly comprises at least four segments connected by at least three hinges. The end-segments of the hinged drive assembly have on their obverse surfaces raised slots through which the band clamp is slipped. The band clamp assembly then fits over and around a cylindrical object such as an oil filter canister. The clamp is tightened around the canister body such that the inner surface of the clamp and the reverse surfaces of the end-segments, which are knurled or scored, are in frictional contact with the canister wall. In the preferred embodiment--a hinged drive assembly having five segments connected by four hinges, rotation of the canister about its central axis is accomplished by one of three means. The tool may be engaged with a ratchet wrench, which fits into a square hole in the center mid-segment, or with a force bar implement, which slips through two rings attached to the obverse surface of the center mid-segment. Torque also may be applied manually by grasping the center mid-segment and employing the necessary wrist action.

    Abstract translation: 用于通过抓住物体并围绕其中心轴线旋转来固定或移除圆柱形物体的工具包括带夹组件和铰接驱动组件。 带夹组件包括带夹,其通过指旋螺钉或六角螺母紧固。 铰链驱动组件包括由至少三个铰链连接的至少四个段。 铰链驱动组件的端部段在其正面上具有凸起的槽,带夹通过该槽滑动。 带夹组件然后装配在诸如油过滤器筒之类的圆柱形物体上和周围。 夹具被紧固在罐主体周围,使得夹具的内表面和端部段的相反表面(其被滚花或刻痕)与罐壁摩擦接触。 在优选实施例中,铰链驱动组件具有通过四个铰链连接的五个部分,罐绕其中心轴的转动由三种装置之一完成。 该工具可与棘轮扳手接合,该棘轮扳手装配在中心中段中的方形孔中,或与力杆工具接合,该力杆工具滑过连接到中心中段的正面的两个环。 也可以通过抓住中间中段并采用必要的手腕动作来手动施加扭矩。
