Claim:
1. An elastic corrugated pipe single-acting cylinder-driven mechanical gripper with a series-connection plate spring framework, wherein a first flexible finger and a second flexible finger that is identical to the first flexible finger are symmetrically installed in guide slots of a palm plate on the left and right, with a center distance defined by a center hole on the palm plate, wherein each of the first and second flexible fingers consists of a finger root, a bendable plate, a thick-plate spring, a thread plate, pressure blocks, a thin-plate spring, a pressure plate, a hinge base, two-force bars, and an elastic corrugated pipe single-acting cylinder; the finger root works as a guide in the guide slots of the palm plate; a first screw passes through a first capsule-shaped groove on the finger root to fix the finger root on the palm plate; the first capsule-shaped groove on the finger root can regulate the center distance of the flexible finger; through a second screw, the thick-plate spring is clamped between the bendable plate and the finger root; two pressure blocks respectively press the thick-plate spring and the thin-plate spring on the thread plate; the thick-plate spring and the thin-plate spring have second capsule-shaped grooves at the parts where they are pressed by the screw plate in order to facilitate regulation on the actual working length of the thick-plate spring and the thin-plate spring; the pressure plate has four threaded holes which are inserted by four third screws; the four third screws penetrate the hinge base to tighten the thin-plate spring on the pressure plate; the thin-plate spring has no hole, facilitating the installation position of the hinge base on the thin-plate spring; and the two ends of the two-force bars are hinges, respectively forming a hinge connection with the hinge base and a hinge support on the elastic corrugated pipe single-acting cylinder; wherein each of the first and second capsule-shaped grooves has two opposite round ends and two straight sides parallel to each other.
