Line wrenches

摘要

A line wrench includes a drive receiving portion, a holder movably connected to the drive receiving portion and a fastener engaging body. The fastener engaging body has a plurality of fastener engaging surfaces defined by a fastener receiving aperture having an axis and a side opening through which an elongate member can enter the fastener receiving aperture by a movement transverse to the fastener receiving aperture axis. The holder is arranged to receive the fastener engaging body, has a free end portion and is movable between a position in which the free end portion is spaced from the drive receiving portion to permit an elongate member to enter the side opening and a position in which the free end portion engages the drive receiving portion such that a drive force applied to the drive receiving portion is transmitted to the holder via the free end portion.

主权项

1. A line wrench comprising:
a drive receiving portion; a clamp portion movably connected to said drive receiving portion; and a fastener engaging body, wherein said fastener engaging body has a plurality of fastener engaging surfaces defined by a fastener receiving aperture having an axis and a side opening through which an elongate member can enter said fastener receiving aperture by a movement transverse to said axis; wherein said clamp portion is arranged to receive said fastener engaging body such that said clamp portion can rotate relative to the fastener engaging body, wherein said clamp portion has a free end portion and is movable between a position in which said free end portion is spaced from said drive receiving portion to permit said elongate member to enter said side opening and a position in which said free end portion engages said drive receiving portion such that, when a drive torque is applied to said drive receiving portion in a drive direction, said fastener engaging body is clamped by said clamp portion for transferring said drive torque to said fastener engaging body to apply said drive torque to a fastener engaged by said fastener engaging body, and wherein, when a torque is applied to said drive receiving portion in a direction opposite said drive direction, the clamp portion releases said fastener engaging body to permit said rotation relative to the fastener engaging body to permit repositioning of the drive receiving portion relative to the fastener engaging body while the fastener engaging body remains in engagement with said fastener.
