发明名称 Saddle structure for an extendable jack
摘要 A saddle structure for a jack device is provided with a rotatable saddle mounted to the fixed saddle of an extension member of a jack device. The rotatable saddle is retained, at least partially, within the fixed saddle for structural reinforcement. The Rotatable saddle provides an interface between the extension member of the jack device and the object to be lifted. The rotatable saddle is freely rotatable about a central axis of the extension member to allow the jack device to be independently oriented with respect to the object to be lifted. The fixed saddle structurally supports the rotatable saddle and is rigidly fixed to the extension member. Such an arrangement provides an adjustable interface between the jack device and the object to be lifted while maintaining the structural integrity of the interface.
