Abstract
A scroll saw includes a base providing a worktable, a motor mounted in the base and having an output shaft, a transmission unit mounted in the base and including first and second transmission devices respectively connected to the two opposite ends of the output shaft of the motor and respectively disposed above and below the worktable, and a saw blade having opposing top and bottom ends respectively connected to the first and second transmission devices of the transmission unit. Thus, when the motor is started, the first and second transmission devices are driven to alternatively move forward and backward in a reciprocating action, and the saw blade is driven to move up and down in a reciprocating action, avoiding vibration of the saw blade and the base and enhancing cutting stability.
