A cylinder, an oil tank, and a piston pump connected through a pair of check valves between the cylinder and the oil tank, and operated by an operating handle pivotally connected to the tool main body are housed in the tool main body, and the piston pump is connected to the cylinder rod. A working part of the tool is attached, a low pressure regulating valve that opens to the cylinder side is connected between the check valve on the cylinder side of the piston pump and the cylinder, and the connecting part and the oil tank are opened to the oil tank side. A return valve is connected between the cylinder and the oil tank and is connected via a high pressure regulating valve and whose opening and closing is controlled by hydraulic pressure in a connecting flow path between the low pressure regulating valve and the high pressure regulating valve. An automatic return type manual hydraulic type device.
