Electronic artificial hand

An electronic artificial hand comprising:

• a plurality of finger groups configured to perform a gripping operation through joint movement in one direction or perform unfolding movement through the joint movement in another direction,
• wherein each of the plurality of finger groups includes:
• a body part including a power section;
• a plurality of knuckles sequentially engaged with each other, one of the plurality of knuckles being connected to one end of the body part;
• a plurality of joints disposed between the plurality of knuckles to perform the joint movement in the one direction or in the another direction at a predetermined angle;
• a tendon path (501) disposed in the respective knuckle to be eccentric in the one direction on the basis of the respective joint;
• a restoring line path formed to be eccentric in the another direction;
• a tendon section having one end configured to be connected to the power section to be wound and another end passing through the body part and the tendon path of the respective knuckle to be connected to the most distal one of the plurality of knuckles;
• and
• a restoring line section having a restoring force and having one end connected to the body part and another end passing through the restoring line path of the respective knuckle to be connected to the most distal one of the plurality of knuckles,
• wherein the body part further includes a first switch configured to stop the power section by using tension of the tendon section which is variable when the power section winds or unwinds the tendon section.
