When the automatic polishing machine needs to move, the third screw 903 is rotated, so that the height of the supporting leg 904 is higher than that of the universal wheel 902, and the universal wheel 902 falls to the ground at the moment, so that the whole machine can be pushed to move. When the automatic polishing machine does not need to move, the third screw 903 is rotated so that the height of the supporting leg 904 is lower than that of the universal wheel 902, and then the nut 905 is rotated to abut against the bottom surface of the second fixing plate 901. At this time, the automatic polishing machine is supported on the ground through the supporting feet 904 and cannot be pushed. The nut 905 butts against the second fixing plate 901, so that the damage of threads caused by the fact that the threads between the second fixing plate 901 and the third screw 903 are only supported by the threads of the automatic polishing machine is avoided.
