1. A concrete cutting machine, comprising:
a saw blade configured to cut concrete;
a motor configured to drive the saw blade to rotate about a first axis;
a bottom plate configured to support the motor and the saw blade, wherein the bottom plate is recessed along the first axis to form a first cutting space for the saw blade to pass through; and
a sliding plate assembly, which is at least partially disposed in the first cutting space to form a second cutting space smaller than the first cutting space,
wherein the sliding plate assembly is detachably mounted to the bottom plate and is movable relative to the bottom plate within a preset range in a first direction parallel to the first axis, and
wherein the first cutting space is open outward along the first axis, and at least a portion of the sliding plate assembly passes through the first cutting space of the bottom plate.
