[0040] In this embodiment, the cutting motor 15 is started, and the driven wheel 20 is driven to rotate through the driving wheel 19 and the belt 18, so that the rotating shaft rotates, so that the old circular saw blade 23 rotates to cut the material. After long-term use, the old circular saw blade 23 needs to be replaced, and the moving motor 16 is started to drive the transmission threaded rod to rotate, so that the slider 28 and the sliding plate 29 slide forward, so that the cutting motor 15 and the old circular saw blade 23 slide forward, and the old circular saw blade 23 is moved to a suitable position to facilitate subsequent replacement operations.
