A head of chip picker is disclosed. The head has a clipping seat and an elastic block. The clipping seat has a body and two arms. The arms are respectively and downwardly extended from two opposite sides of an inner top surface of the body, so a cavity with a wide-top and narrow-bottom shape is constituted among the inner top surface and the arms. The elastic block matches the cavity and is laterally inserted into the cavity. The elastic block is not deformed after inserting into the cavity and provides a flat bottom surface.
