Vibration reduction chain saw

The invention belongs to the technical field of chain saws, and relates to a vibration reduction chain saw which comprises a front handle and a rear handle which are connected with a power assembly. The power assembly comprises an air cylinder body and a crankcase, at least three sets of vibration reduction mechanisms are arranged on the vibration reduction chain saw, and the first vibration reduction mechanism is arranged at the upper side of the air cylinder body; the second damping mechanism is arranged at the front side of the axis of the air cylinder body; and the third damping mechanismis arranged at the rear side of the axis of the air cylinder body and comprises a spiral spring. According to the vibration reduction chain saw provided by the invention, the vibration reduction mechanisms are respectively distributed at the main vibration source of an engine, so that the vibration energy is more uniformly distributed and is more effectively reduced, and the operation comfort is greatly improved. 本发明属于油锯的
