1. A wearable device configured to be worn by a user, comprising:
an upper thigh frame;
a lower thigh frame;
a motion frame connected between at least the upper thigh frame and the lower thigh frame, the motion frame including a plurality of segment frames, each of the segment frames being pivotal relative to at least one other segment frame, the plurality of segment frames including a upper segment frame and a lower segment frame;
a rotary shaft connecting the upper segment frame and the lower segment frame;
an elastic body enclosing the rotary shaft; and
a stopper configured to restrict an angle of rotation of the upper segment frame with respect to the lower segment frame,
wherein the motion frame is configured to allow an angle between the upper thigh frame and the lower thigh frame to be adjusted using the rotary shaft, wherein the motion frame is configured, using the rotary shaft, to pivot relative to each of the upper thigh frame and the lower thigh frame,
wherein one end portion of the elastic body is configured to be fixed to the upper segment frame, and the other end portion the elastic body is configured to be fixed to the lower segment frame,
