Through the pressure build-up in the oil pipe, the hydraulic anchor claws extend outwards under the action of liquid pressure, clamp the inner wall of the casing, and realize the anchoring action. When the pressure of the casing is balanced, the anchor claws are retracted under the elastic force of the spring in the baffle, and the anchoring effect is released.
