The invention discloses a reducing impact insertion-cutting type annular banana comb cutting device. The reducing impact insertion-cutting type annular banana comb cutting device comprises a lifting frame and at least three cutting units, wherein the lifting frame is provided with a workbench and a lifting mechanism for lifting and lowering the workbench; the cutting units are annularly arranged on the workbench; the cutting units comprise parallelogram mechanisms, comb cutting knife groups and knife group synchronous controllers. The lifting mechanism of the banana comb cutting device has an impact effect. When fruit stems are in contact with hard blades or soft blades during banana comb cutting, insertion cutting of banana stems under the impact of the hard blades and the soft blades can be realized by controlling the revolving of runners, so that the aims of removing stalks and cutting combs are fulfilled, the cutting quality can be improved, the comb cutting time is shortened, and the efficiency is increased.
