Patent attributes
A backpack tool, a backpack blower and a control handle assembly are provided by the present invention. The backpack tool includes a battery pack for providing electrical energy, a power assembly electrically connected with the battery pack to convert the electrical energy provided by the battery pack into mechanical energy, and a backpack assembly carried on the human back to support the battery pack and the power assembly. Both the battery pack and the power assembly can be carried on the human back using the backpack assembly, so that the weight carried by the arms of the worker can be reduced. The battery pack serves as a power source that reduces the noise and vibration caused by the backpack tool during operation as compared with a gasoline powered backpack tool.
