ABSTRACT:
A driving mechanism for a scroll sawing machine, which comprises a motor set in parallel with two suspension arms which have a scroll saw blade retained therebetween, and sector-shaped counter weight mounted on the shaft of such a motor and coupled with an universal link which has an opposite end secured to the suspension arms. The rotation of the motor drive the universal link to carry the suspension arms and the scroll saw blade to make a sawing motion for cutting something. Because the motor is set in parallel with the suspension arms, the saw bench is permitted to incline leftward and rightward during sawing operation.
