ABSTRACT:
A working machine includes a blade seat movable relative to a sheet plate, and a safety protective device mounted on the blade seat to cover the blades of the blade seat and including at least one swing member pivotally mounted on the blade seat, and a protective board pivotally connected to the at least one swing member. Thus, when any portion of the protective board is pushed by the sheet plate, the whole protective board is driven to pivot relative to the blade seat so that the protective board is moved upward and downward in a whole manner without deflection.
