When in use, the lower rotating device can be rotated to a suitable angle and then the upper rotating device can be adjusted to achieve the required inclination angle. Finally, it is fixed with a fixed shaft to prevent it from falling off during work and causing danger, avoiding the safety hazards caused by traditional pure manual grinding, and avoiding the fatigue accumulation caused by long-term manual work.
