A saw contains: a saw blade, a handle, and an auxiliary fixing device. The saw blade includes a serrated sawing section, a connection shaft, a fixing post defined between the connection shaft and the handle. The auxiliary fixing device includes two clamp extensions, wherein two front ends of the two clamp extensions are connected together by using a guiding section of the auxiliary fixing device. The auxiliary fixing device also includes two first elastic rings respectively rolled on two rear ends of the two clamp extensions, two second elastic rings individually formed in the two first elastic rings. Each second elastic ring is eccentric with each first elastic ring and its diameter is less than that of each first elastic ring, each second elastic ring is rotatably fitted with the connection shaft, and each first elastic ring abuts against the fixing post as not using the saw.
