Slicing shears with base and hooked mouth

Provided is a pair of slicing shears with a base and a hooked mouth. The thickness of a sheared slice can be adjusted, a sheared object can be prevented from sliding to a shear head and consequently sliding out of a shear opening, and the shears can be used on a platform instead of being held by hand. The slicing shears are composed of a flat shear mouth, the hooked shear mouth, the pier base and a baffle. The hooked shear mouth and the pier base are connected into a whole. The hooked shear mouth is in a semicircular arc shape, and the flat shear mouth and the baffle are located on the two sides of the hooked shear mouth respectively; the flat shear mouth and the hooked shear mouth are connected through a shear shaft, and the opening of the hooked shear mouth faces the flat shear mouth. The pier base and the baffle are located on the same outer side of the hooked shear mouth, and the baffle shields the outer side of the whole hooked shear mouth. A strip-shaped object is placed on the hooked shear mouth and presses the baffle on the outer side in an abutting mode, and a flat shear mouth handle is pressed to the pier base to shear the strip-shaped objected into slices; screws perpendicularly fixed to the outer side of the hooked shear mouth are outwards sleeved with compression springs and the baffle in sequence, and adjusting bolts are screwed on the screws. The adjusting bolts are screwed to adjust the distance between the baffle and the hooked shear mouth, and the thicknesses of the sheared slices can be decided.
