The invention discloses a multi-functional dicer, and relates to the field of technical equipment for fruit dicing. The multi-functional dicer comprises two stand columns and a fixed frame mounted on the stand columns. A hopper is fixedly mounted on the fixed frame. A grid-shaped dicing knife is mounted in the hopper. A slideable slitting knife is arranged below the dicing knife. The tail of the slitting knife penetrates from the hopper. A mounting rack is mounted on the stand columns. A driving motor is mounted on the mounting rack. A screw rod is fixedly connected with an output shaft of the driving motor by means of a coupling. A nut matched with the screw rod is arranged on the screw rod. A connecting rod is hinged to the nut. The other end of the connecting rod is hinged to the tail of the slitting knife. A mounting plate is fixedly mounted at the upper ends of the two stand columns. A pushing cylinder is mounted on the mounting plate. A piston rod of the pushing cylinder penetrates the mounting plate downwards. A fixed plate is mounted on the piston rod of the pushing cylinder. A plurality of push rods disconnected with one another are arranged on the fixed plate. The multi-functional dicer has the advantages that dicing is uniform, manual operation is not needed, use is convenient, and the labor is reduced.
