The invention relates to a plum carving and processing mechanism, and belongs to the field of food processing machines. The plum carving and processing mechanism comprises bases, connecting sleeves, upper covers, platens, platen shafts, a spring, connecting rods, knife rest shafts and a plurality of carving knife sets, wherein each carving knife set is installed on one upper knife rest shaft and one lower knife rest shaft, the knife rest shafts are installed between inner cylinders of the bases and the connecting sleeves, and the carving knife sets can conduct rectilinear motion along the knife rest shafts. When the platens are pressed downwards, the platens drive one ends of the connecting rods to move downwards, the other ends of the connecting rods drive the carving knife sets to move inwards along the knife rest shafts, and thus blades on the carving knife sets are driven to move towards plums in the inner cylinders, and plum carving operation is completed. After carving is completed, under the action of the spring, the platens move upwards, and the carving knife sets are driven to return back. The plum carving and processing mechanism is easy to operate, can be suitable for small-scale processing plants during manual operation, and can serve as complete equipment for processing main parts into large-scale production by adding a power device and a transmission device, thusrelieving the labor intensity, improving the working efficiency and reducing the labor cost.
