Summary:Provided is a labor-saving transmission arm. The invention belongs to the field of mechanics. The technical problem to be solved is that labor is saved for equipment needing driving force, and energy can be saved through labor saving. According to the technical scheme, the labor-saving arm is characterized in that a plurality of pulleys are combined according to the pulley labor-saving principle, energy needed by driving is reduced, and the labor-saving arm is wide in application range. When the device is mounted on an automobile driving shaft, the endurance of an automobile can be prolonged by many times; the device is arranged on an exhaust fan and a compressor of an air conditioner. When the device is arranged on the traction of the elevator, the elevator can save much electricity; when the device is installed on a crane or an excavator, large heavy objects can be carried with small power. Most of fuel can be saved when the device is mounted on power equipment of warships, aircraft carriers and airplanes.
