A movable device is movably provided on the base to be moved between a distal position and a proximal position. A driven wheel is pivoted on the movable device. A band saw is provided around the driving wheel and the driven wheel. A fine adjusting device is engaged with the movable device. A transmission device is movably disposed on the base with an end connected with the fine adjusting device. A cam device is pivoted on the base having a periphery against the transmission device. The cam device is turned between a first position and a second position to move the movable device between the distal position and the proximal position. A handle is connected to the cam device to be operated for turning the cam device.
