Rotary woodworking machine

摘要

A rotary woodworking machine includes an upright shaft rotatable relative to a plunger and driven by a rotary transmitting shaft which is driven by an output shaft of a motor. A lifting lever has a fulcrum end pivoted on a support frame, and a force end coupled to the output shaft by means of a cam member such that a drive force of the output shaft is transmitted to effectuate reciprocating upward and downward movements of the force end. The upward movement of the force end will cause an intermediate weight portion of the lever to lift the upright shaft as well as the plunger from a lower position to a higher position.
