Abstract: A dicer is provided with a power output shaft in the container, and deceleration components and cutter disks on the output shaft. The cutter disks comprises a slicing cutter disk and a dicing cutter disk, a block in the container cover, a handle in the slicing cutter disk, and through-holes in the dicing cutter disk. The dicer is able to cut food into pieces with the same shape and size, and the dicing effectiveness is substantially perfect. The deceleration components have simple structure, which occupy small space and are convenient for household use. The handle is provided on the slicing cutter disk to facilitate detachment of the slice cutter disk for cleaning, and a through-hole is defined in the dicing cutter disk to facilitate detachment of the cutter disk for cleaning. The block makes the slicing cutter disk stable when rotating, to facilitate dicing.
