Abstract
A transmission mechanism for a scroll sawing machine is disclosed. An upper counter weight and a horizontal counter weight are secured to the lower end of a rocker arm, which has its top end secured to the scroll saw blade upper driving arm, and carried to move by the transmission shaft of a motor. The rotation of the transmission shaft of the motor drives the upper counter weight to rotate so as to eliminate any possible vertical shock waves, and simultaneously drives the rocker arm to move up and down so as to eliminate any possible horizontal shock waves.
