A multi-degree-of-freedom automatic center-adjusting device, a hydraulic quick-coupling device, and rescue equipment are provided. The automatic center-adjusting device includes an active coupling valve set, a spring, and a dynamic adjustment swing rack. A first end of the dynamic adjustment swing rack is fixed to operation tools, and a second end of the dynamic adjustment swing rack is connected to the active coupling valve set through the spring. The dynamic adjustment swing rack includes a frame, a limit slot, and a spring limit cylinder, wherein the frame is used to support and fix the active coupling valve set, the limit slot is used to define a limit activity position of the active coupling valve set, and the spring limit cylinder is used to constrain the spring. The automatic center-adjusting device is used to solve technical problems of position errors and a center mismatch in a coupling process.
