[0002] The patent number is: ZL202222593392.X, and the patent name is: A Chinese utility model patent for an electric-driven two-finger opening and closing mechanical gripper, which discloses an electric opening component; specifically, the electric opening component of the above-mentioned electric-driven two-finger opening and closing mechanical gripper includes a stepper motor, a harmonic reducer, an output shaft, a screw rod, a roller, a connecting rod assembly, a fixed support, and a chuck; when in action, the stepper motor converts the rotation of its motor shaft into the rotation of the output shaft through the harmonic reducer. When the output shaft rotates, the screw rod rotates back and forth. When the screw rod rotates forward, the roller moves forward synchronously. Under the coordinated limiting action of the connecting rod assembly and the fixed support, the chuck rotates around the pin shaft used to rotate and connect the fixed support and the chuck, and the chuck opens; when the screw rod rotates backward, the roller moves backward synchronously. Under the coordinated limiting action of the connecting rod assembly and the fixed support, the chuck rotates around the pin shaft used to rotate and connect the fixed support and the chuck, and the chuck closes.
