Bionic artificial finger

The utility model discloses a bionic artificial finger, and mainly relates to the technical field of bionic artificial fingers. Comprising fingertip knuckles, one ends of the fingertip knuckles are rotationally connected with rotating knuckles, the ends, away from the fingertip knuckles, of the rotating knuckles are rotationally connected with finger root knuckles, connecting frames are installed at the ends, close to each other, of the fingertip knuckles and the finger root knuckles, adjusting devices are arranged on the bottom faces of the fingertip knuckles, and each adjusting device comprises a connecting groove. The bionic prosthetic finger has the advantages that the problems that in the process of operating and using the whole bionic prosthetic finger, the prosthetic finger needs to be limited through a plurality of fixing assemblies, so that the prosthetic finger is prevented from falling off, the prosthetic finger installation operation is complex at the moment, and due to the fact that the whole bio
