When motor No. 1 203 drives the threaded shaft 206 to rotate, the threaded shaft 206 drives the connecting frame 204 through its outer wall thread, and drives the cutting machine 2 and the cutting blade 202 to move vertically along the outer wall of the slide rail 205 through the connecting frame 204, so that the cutting blade 202 can be precisely adjusted in height, thereby achieving accurate cutting of different depths of the road surface, while improving the cutting accuracy and efficiency.

[0027] After aligning the groove at the center of the bottom surface of the water storage barrel 302 with the positioning plate 304, the water storage barrel 302 is placed in the center of the positioning frame 301. When the groove at the bottom of the water storage barrel 302 contacts the top inclined surface of the positioning plate 304, the groove at the bottom of the water storage barrel 302 pushes the positioning plate 304 along the outer wall of the limiting rail 303 toward one end of the positioning spring 306, and compresses the positioning spring 306. When the outer wall of the bottom end of the water storage barrel 302 contacts the bottom end of the inner wall of the positioning frame 301, the positioning spring 306 pushes the positioning plate 304 toward the side of the groove, so that the top side of the positioning plate 304 and the bottom side of the water storage barrel 302 are engaged with each other, and the water storage barrel 302 is firmly fixed in the center of the positioning frame 301.

When the water storage barrel 302 needs to be replaced, it is only necessary to push the pressure plate 305 toward the inside of the positioning frame 301, so that the pressure plate 305 pushes the positioning plate 304 to slide along the limit rail 303, and the positioning plate 304 is separated from the bottom side of the water storage barrel 302, and the water storage barrel 302 can be removed from the top of the device, thereby realizing the rapid replacement of the water storage barrel 302 through the cooperation of the positioning plate 304 and the positioning spring 306.
