A spring 14 may be provided between one of the bearings 132 and the inner upper end of the fixed seat, so that the rotating seat 12 can move elastically in the axial direction. After the cutter head 1 is installed on the motor drive shaft of the food cooking machine, the passive joint 131 directly engages with the active joint located on the drive shaft. Therefore, when the motor is running, the drive shaft will directly drive the central shaft 13 to rotate, causing the twist The meat blades 15 rotate at a constant speed, which does not have a variable speed effect of slowing down or speeding up.
