Abstract：
 The invention relates to tendon link under-actuated mechanical finger device which includes the first and second finger sections, under-actuated joint. The under-actuated joint includes joint axis, drive slider, tendon line, and spring piece. The joint axis is set at the first finger section. The second one is set at the joint axis. One end of the tendon line is fixed at the end of the second finger section. Another end is passed through the upper of the first one and connected with its lower. The drive slider is embedded in the first finger section and touched with the tendon line. The spring piece is set between the first and second knuckles. The device can be used as impersonated one finger or parts, or connected in series to form high under-actuated finger. The device has the advantages of simple, reliable structure, little volume, light weight, low control system demand.
