Claims

[Scope of utility model registration request]

The base end of a boom is rotatably attached to the main body, both ends of a boom cylinder are attached to the main body and the boom, the base end of an arm is rotatably attached to the tip of the boom, and an arm cylinder is attached to the boom and the arm. Attach both ends, attach the base end of the packet cylinder to the arm, and rotatably attach a working device to the arm and the tip of the packet cylinder,
In a working device using a hydraulic excavator configured to operate the working tool of the working device by a hydraulic actuator for operating the working tool, an electromagnetic switching valve is installed in the middle of the piping between the hydraulic power source of the main body and the packet cylinder. At the same time, this electromagnetic switching knob is attached to the arm, and the space between the electromagnetic switching valve and the hydraulic actuator for work is arranged, and the desired connection between the packet cylinder and the hydraulic actuator for the work tool is achieved by switching the electromagnetic switching valve. A hydraulic circuit in a working device using a hydraulic excavator, characterized in that it is configured to operate one side of the hydraulic circuit.
