Abstract
An adjusting device has a driving disk with two diametrically oppositely formed arcuate tracks formed thereon and a driven plate securely connected to the chain saw and having multiple bosses evenly and horizontally distributed on the driven plate. The two arcuate tracks are alternately received between two adjacent bosses such that when the driving disk rotates, the driven plate is moved linearly, which results in the adjustment of the tension of the chain saw.
