The invention discloses a variable-rigidity flexible knuckle capable of adjusting angle. The variable-rigidity flexible knuckle comprises a connecting rod, a bracket, a connecting-rod mechanism and at least one group of knuckle mechanism, wherein each group of knuckle mechanism comprises two hook tips; a neck-shaped cylinder is coaxially arranged on the periphery of the middle part of each hook tip; an annular variable-rigidity flexible joint is coaxially arranged on the periphery of the neck-shaped cylinder; the longitudinal cross section of the joint is arched; the joint is provided with two arched end parts with relatively low rigidity and an arched middle part with relatively high rigidity; two round through holes are at least formed in the bracket; a convex surface of the arched middle part is matched with a neck-shaped concave part of the neck-shaped cylinder; a concave surface of the arched middle part is buckled with the inner side edge of the corresponding round through hole. After the structure is adopted, due to the fact that the connecting-rod mechanism is arranged, the included angle between the hook tip and local normal of a wall surface can be adjusted, mechanical self locking is easy to form, and the grasping stability is high; due to the fact that variable-rigidity flexible joint is arranged, the hook tip can flexibly move in each direction, the best grasping point can be quickly found, and higher grasping force is convenient to generate.
