[0038] If it is necessary to smooth the higher position, the second lifting control mechanism 12 is activated to raise the lifting frame 2, the first lifting control mechanism 3, the angle control mechanism 4 and the smoothing mechanism 5 together. Then the high wall surface is smoothed according to the above steps.
