Abstract:
Disclosed in the present invention are a low-power-consumption cutting chain and a chain saw having same, the cutting chain comprising: a plurality of transmission pieces; a plurality of connection pieces; a plurality of cutting blades, each of which has an upper cutting edge and a depth limiting portion for guiding the upper cutting edge; and a plurality of pivots, which are connected to the transmission pieces, the connection pieces and the cutting blades in a hinged manner, wherein the product of the maximum cutting width, the maximum height and an average boundary line is between 130-270 mm3, including 130 mm3 and 270 mm3. The working efficiency of the cutting chain of the present invention is at least 30% higher than that of a conventional chain, and a load thereof is reduced to 30-60% of the conventional chain. The chain has a small size, a light weight and a low load and a low energy consumption, and, compared with the conventional chain, saves on labor and money, is more suitable for the application of a new-type lithium battery product, and greatly extends the usage time of a product in the wild, thereby better meeting the large workload of a user in the wild, and laying a solid foundation for a lithium battery chain saw to replace a gasoline chain saw and other high-polluting chain saws.
