The invention relates to a manipulator comprising a connector, upper hydraulic devices, upper arms, lower arms, a mounting plate and lower hydraulic devices. The manipulator is characterized in that the mounting plate is welded together with the connector, three mounting heads are arranged on each of the upper and lower sides of the mounting plate, the three mounting heads on the upper side are used for mounting the upper hydraulic devices, the three mounting heads on the lower side are used for mounting the lower hydraulic devices, the other ends of the upper hydraulic devices are connected with protrusions in the middles of the upper arms, one ends of the lower hydraulic devices are connected with the protrusions in the middles of the upper arms while the other ends of the same are connected with the lower arms, the lower arms are further connected with the upper arms, the upper arms, the lower arms, the upper hydraulic devices, the lower hydraulic devices and the mounting plate are all in pin connection mutually, connection parts can rotate around corresponding pins, and the lower portion of each lower arm is provided with anti-slip lines. The manipulator is simple and reasonable in structure, and can grab or carry different complex-surface bulk objects safely and rapidly to enable carrying operation to be safe and efficient.
