The main feature of the device is that two clamping blocks are pivotally mounted on a bracket and each of the clamping blocks has a tooth portion and a cam portion formed on an outer surface thereof. An elastic member is located between the bracket and the clamping blocks. A button connected to a rod, which passes through a cover plate of the bracket and includes a tooth slot for engaging with the tooth portion of the clamping block. When the rod moves in an axial direction, the two clamping blocks are brought to rotate so that the cam portion can fasten or loosen the saw blade, and thereby the saw blade can be mounted and demounted conveniently and rapidly.
