[0030] When it is necessary to grind some walls in a narrow space, the electric telescopic rod 9 is extended and retracted to drive the connecting block 4 at the bottom to tilt. After the connecting block 4 is tilted, it rotates at the bottom end of the connecting rod 6. After the connecting block 4 is tilted, the bottom protective plate 1 is tilted. After the protective plate 1 is tilted, the internal grinding assembly is tilted, thereby adjusting the angle between the protective plate 1 and the connecting rod 6, so that the staff can hold the connecting rod 6 to extend the grinding assembly into the working area for grinding.
