The invention discloses a rigidity-controllable ankle joint device for a climbing robot, and relates to the field of climbing robots, the rigidity-controllable ankle joint device comprises a soft multi-cavity element and matched parts thereof, a ball blocking mechanism and an attachment tail end, one end of the ball blocking mechanism is connected with the soft multi-cavity element and the matched parts thereof, and the other end of the ball blocking mechanism is connected with the attachment tail end. And the other end of the ball retarding mechanism is connected with the attachment tail end. The ankle joint device is active and controllable, complete in function, large in variable rigidity range and small and compact in structure, the joint rigidity can be changed with small air pressure, the requirement for a pneumatic system of the robot is low, control is easy, the structural rigidity of the ankle joint device is actively regulated and controlled, and the mechanical strength of the robot is improved. The low-rigidity state meets the requirement for adaptability of contact between the attachment tail end and the wall face, the high-rigidity state meets the requirements for transmission accuracy and high efficiency when the attachment tail end and the wall face are desorbed, and realizability of the ankle joint to a complex tail end track is achieved.
