Cylinder force multiplier for multi-point board cutter

An air cylinder output doubling device of a multi-point board splitting machine relates to the technical field of the PCB board cutting machinery and especially indicates an air cylinder output doubling device of the multi-point board splitting machine used for splitting the PCB board. A technical proposal of the air cylinder output doubling device is that one end of a push connecting rod is connected with the outer end of a piston rod of the air cylinder, and another end of the push connecting rod is connected with two connecting rods, wherein another end of one connecting rod is connected with one end of a knife rest, and another end of another connecting rod is connected with a stationary block; another end of the knife rest is connected with another stationary block. The utility model can realize the purpose of the output doubling.
