Disclosed is a manipulator, which is characterized in that the invention comprises three parts: a jaw, a shaft and a beam-barrel. The jaw comprises a bracket and at least two claws. The middle parts of the two claws are hinged on the bracket whose back end is connected with the shaft. A hydraulic cylinder is respectively arranged at the rear end of the two claws. Pistons of the two hydraulic cylinders are connected with corresponding rear ends of the claws. The center of the shaft is provided with oil supplying holes which are respectively connected with the two hydraulic cylinders so as to form a lever-type grasping mechanism. The shaft is rotationally supported inside the beam-barrel. A first umbrella-shaped gear arranged on the output shaft of a hydraulic motor meshes with a second umbrella-shaped gear which is correspondingly connected on the shaft so that a rotating mechanism where the jaw can rotate around the shaft by 360 degrees is formed. The manipulator has characteristics of reasonable design, high performance price ratio, simple structure, convenient using, high work efficiency and good reliability.
