A rapid hand-cranking egg
cutting device comprises a
handle, a connecting rod, a transmission shaft, an upper cylindrical
cam, a lower cylindrical
cam, a tool rest, a guiding flat key, a fastening screw, a sawtooth-shaped cutter, an upper base, an upper egg base, a lower base, a lower egg base, guide columns, nuts, limiting blocks, a small spring and a big spring. The rapid hand-cranking egg
cutting device is novel in structure, high in egg
cutting efficiency and good in safety; different kinds of eggs can be
cut by replacing different upper egg bases and lower egg bases and debugging other parameters, and the application range is wide; the sawtooth-shaped cutter is adopted, and thus edge cutting is more effortless; and the damage to the edge of an
eggshell is minimized after an egg is
cut, and the separation faces of the egg are flat and attractive.
