The two-degree-of-freedom finger mechanism of the five-finger manipulator is suitable for five-finger manipulator equipment of a humanoid robot and serves as a ring finger and little finger module. The robot consists of two parts, namely a finger bending assembly and a finger swinging assembly. The finger bending assembly drives a ball screw nut pair through a driving motor to convert rotary motion into linear motion, and then a ball nut drives an elastic connecting rod and finger joints to achieve bending motion of fingers. The finger swinging assembly drives a bevel gear set through a driving motor, and after the direction of rotating motion is changed, a connecting rod and finger joints are driven through a universal joint to achieve the swinging action of fingers. According to the two-degree-of-freedom mechanical finger, the two assemblies are ingeniously combined to one finger, and the overall size of the mechanical finger is reduced while two-degree-of-freedom movement is achieved. And in combination with the use of the elastic connecting rod, the driving motor is protected, and the action area of the manipulator and the grabbed object is increased.
