The invention discloses a single fulcrum ultra-wide permeable oscillating wave making machine comprising a servo motor connected with an electric cylinder. A terminal of the action push rod of the electric cylinder is hinged onto one end of a connecting rod, the other end of the connecting rod is hinged onto one end of an oscillating rod, the other end of the oscillating rod is hinged onto a wave making plate bracket, and one point of a rod body of the connecting rod is hinged on one side of a bracket body through the bracket; a cylinder tube of the electric cylinder is provided with a rotating shaft; the rotating shaft of the electric cylinder is rotatably fixed on a top end of the bracket body. The wave making machine disclosed in the invention is driven via a single fulcrum; the wave making machine is small in driver element quantity and low in production cost; the wave making machine is driven by the servo motor and high in driving force and reliability; a lever principle is used, the oscillating rod is used for amplifying the movement of a driver into movement of a wave plate; driver stroke is effectively used, and wave making ability is improved.
