Cutting device

The invention provides a cutting device which has the advantages that the overall structure of the device is simple and miniaturized; and the quantity of components is reduced, so that the manufacture cost is reduced. The cutting device comprises a processing feeding mechanism, a moving-out/moving-in mechanism, a holding component, a pair of limiting pins, a carrying and moving component, a temporary placement mechanism, an openable component and a lifting component, wherein the processing feeding mechanism comprises an X-axis guide rail, and the X-axis guide rail can ensure that a working table can be supported to move between a processed object assembly and disassembly area equipped with the temporary placement mechanism and a processing area equipped with a cutting mechanism in the X-axis direction; the moving-out/moving-in mechanism comprises a supporting base table; the holding component is disposed on the supporting base table and used to hold a processed object stored in a box; the pair of limiting pin
