[0053] The sharpening machine body 100 includes a sharpening wheel 110 and a drive mechanism 120 for driving the sharpening wheel 110 to rotate;

[0054] The grinding holder 200 is used to fix cutting tools, and the grinding holder 200 includes a limiting seat 210;

[0055] The whetstone dressing frame 300 is used to dress the sharpening wheel 110, and the whetstone dressing frame 300 includes a diamond tip pen 310.

[0056] Mounting base 400 is placed on both sides of the grinding wheel 110 and can be used to mount the grinding frame 200 or the grinding stone dressing frame 300.

[0057] The grinding wheel 110 and drive mechanism 120 are mounted on the grinding machine body 100. The drive mechanism 120 controls the rotation of the grinding wheel 110 to grind the cutting tool. Before grinding, the cutting tool is hinged to the grinding stand 200 by bolts or other fasteners, and then limited by the limit seat 210. The cutting tool usually has multiple cutting edges, and rotating the cutting tool facilitates grinding multiple cutting edges. With prolonged use of the grinding wheel 110, the ground surface will become irregular and uneven. The grinding wheel 110 is ground flat by using a diamond tip pen 310 placed on the grinding wheel dressing holder 300 to flatten the grinding surface. The grinding wheel holder 200 and the grinding wheel dressing holder 300 are easily installed and replaced by the mounting base 400. When sharpening is needed, the grinding wheel holder 200 is installed to sharpen the grinding wheel 110. When the grinding wheel 110 needs to be dressed, the grinding wheel dressing holder 300 is installed on the mounting base 400 corresponding to the grinding surface that needs to be dressed.
