    • Power assisted wrenching tool (10) for the attachment of fasteners (42, 34) in loose and interference fit applications, and particularly for use with frangible fasteners (34). The improvement comprises a readily removable key (36) which is used to immobilize the bolt (42) during attachment of a threaded fastener (44), typically in a loose fit application. The key (36) is retained in the wrenching tool assembly by a detent ball (64) which is positively locked in the center core (48) of the holder member (38) of the wrenching tool and can only be disengaged by the axial alignment of the holder member (38) and the socket drive member (50) of this assembly. The tool is thus easily adaptable for the application of fastners in either loose or interference fit applications.
    • 用于在松动和过盈配合的应用中紧固件(42,34)的附接,特别是用于易碎紧固件(34)的电动辅助扳手工具(10)。 该改进包括易于移除的键(36),其用于在螺纹紧固件(44)的附接期间固定螺栓(42),通常为松配合应用。 钥匙(36)通过止动球(64)保持在扳手工具组件中,该止动球被积极地锁定在扳手工具的保持器构件(38)的中心芯部(48)中,并且只能通过轴向对准 (38)和该组件的插座驱动构件(50)。 因此,该工具可以很容易适用于在松动或过盈配合的应用中应用快门器。
