When the waste chips generated during the internal operation of the high-precision CNC milling machine splash to the inner end of the observation window 211, it will affect the observation line of sight. At this time, the rotating rod 212 is rotated, thereby driving the first bevel gear 213 to rotate synchronously. Under the meshing action of the first bevel gear 213 and the second bevel gear 214, the second bevel gear 214 is driven to rotate synchronously, and then the threaded rod 215 is driven to rotate synchronously. Under the action of the thread, the sliding seat 216 is driven to move synchronously, and the cleaning plate 219 is driven to move through the linkage of the connecting rod 217 and the connecting column 218, so that the cleaning plate 219 cleans the inner end of the observation window 211, which can keep the observation window 211 clean and convenient for observation.
