Carving machine with cutter protection function

The utility model relates to the technical field of carving equipment, in particular to a carving machine with a cutter protection function, which comprises a working table, a protection mechanism and a cleaning mechanism, the protection mechanism is positioned at the top of the working table, the cleaning mechanism is positioned in the working table, and grooves are arranged on two sides of the outer wall of the top of the working table. Grooves are formed in the two ends of the rotating shaft, first sliding blocks are slidably connected to the grooves, hydraulic cylinders are installed at the tops of the two first sliding blocks, the same sliding rail is installed at the tops of the two hydraulic cylinders, and a second sliding block is slidably connected to the sliding rail. The third sliding block counteracts the counter-acting force of the spring and starts to move downwards along the slope, if the rotating speed of the graver is greatly reduced or the graver stops rotating under special conditions, the
