In addition, the setting of the dust-proof net can block the entry of ash and dust. After the controller body 1 is used, the servo motor 541 can be operated. When the servo motor 541 operates, it will drive the right threaded rod 54 to rotate, and then driven by the belt 56, the threaded rods 54 on both sides will rotate synchronously. When the threaded rod 54 rotates, it will drive the threaded sleeve 53 to move forward, and when the threaded sleeve 53 moves forward, it will drive the sealing doors 51 on both sides to move forward through the adjacent fixing rod 52, realizing the sealing of the adjacent fixing frame 4, and can completely isolate the entry of dust and powder.
