The disclosure discloses an electric-pneumatic hybrid-driving flexible manipulator with spring framework from plates of special-shaped thickness, including a screw shaft motor, an upper seat plate, guide coupling rods, linear bearings, a driving plate, a push plate, short push rods, connecting rods, a bottom seat plate, flexible fingers, a rotating finger holder, a long push rod, a small support, tension springs, single-head bellows muscles and a ridged push plate. The framework of the flexible fingers is a thickness special-shaped plate spring designed according to the principle of equal strength. In the disclosure, through the control of a motor, an angle between a finger knuckle and a grasped object can be adjusted to realize the adjustment of the position of a contact point. To adjust the position of the contact point of the grasped object, the acting point of the contact force and the direction of the acting force can be selected according to situations, so that the grasping is more accurate and reliable. At the same time, the angle between the finger knuckle and the grasped object can be adjusted to adapt to a larger change in size of the grasped object. In the disclosure, a pneumatic system is large in gain and the pneumatic bellows muscles are light, so that the response is quick and the buffering effect is good.
