Technical Field
[0001] The utility model belongs to the technical field of angle grinders, and particularly relates to an angle grinder with rotatable adjustment. Background Art
[0002] For traditional lithium battery angle grinders, the head of the machine body and the tail of the foot plate are integrated and cannot move. Since the tail of the foot plate is equipped with function operations such as a battery pack, a speed adjustment button, and a power display, the positions of these function settings do not conform to our usual operating habits and vision. When the user inserts or removes the battery pack, it is not convenient, and the battery pack is also likely to bump into the arm. At the same time, the arm blocks the speed adjustment button and the power display, resulting in extremely poor operating experience for the user. During the grinding operation, the battery pack will interfere with the end face of the object, affecting the grinding angle and thus the grinding effect. Therefore, it is necessary to design an angle grinder with rotatable adjustment to overcome the above difficulties. Summary of the Invention
