A stirring cutter capable of doing vertically reciprocating circulating motion comprises a gearbox and a stirring cutter assembly; the stirring cutter assembly comprises a blade and a cutter bar, a reversing device is arranged at the upper end of the cutter bar, and the stirring cutter assembly can do vertically reciprocating circulating motion through motion conversion of the reversing device; an output shaft A and an output shaft B are arranged on the gearbox, the cutter bar is in linkage with the output shaft A or the output shaft B, the reversing device is in linkage with the output shaft B or the output shaft A, the gearbox can drive the reversing device to drive the stirring cutter assembly to do vertically reciprocating circulating motion while driving the stirring cutter assembly to rotate at high speed. While a stirring cutter rotates in the own axial direction, the function of automatic vertically reciprocating circulating motion, and in this way food in a container is stirred and cut fully. The rotating speed of the stirring S cutter and the speed of vertically reciprocating circulating motion frequency are separated, by designing the gear ratio of the gear, so that the rotating speed and the automatic vertically reciprocating circulating motion frequency meet requirements, and the stirring cutter has the advantages of being simple in structure and high in stirring and cutting efficiency.
