placing the four-branch pipe 1 on a processing table 2, respectively extending four high-pressure gas columns 3 from the mouth parts of the four branch pipes, enabling the mouth part of the main branch pipe to face the processing table 2, starting an air compressor through a double-control switch 7 on the processing table 2, simultaneously enabling a controller to receive an electric signal for starting the air compressor through the double-control switch 7, and lighting a yellow indicator lamp; the air compressor inflates air into the four high-pressure air columns 3, the four-branch pipe 1 is lifted up under the action of the high-pressure air columns 3, and the four-branch pipe circularly moves by taking the bottom of the high-pressure air columns 3 as the center of a circle; in the process that the four-branch pipe is lifted up, the four-branch pipe pushes the positioning block 4 which is abutted against the four-branch pipe, and the sliding block 9 is driven by the positioning block 4 to move from the left end of the transverse sliding groove 5 to the polishing area.

The method comprises the steps that an air compressor is set to be started within 5 seconds in advance, when the pressure in a high-pressure air column 3 reaches a threshold value, a pressure relief valve starts to relieve pressure, and the high-pressure air column 3 is in a filling state; because the annular air bag 302 is arranged on the cylindrical surface of the high-pressure air column 3, and the annular air bag 302 is communicated with the high-pressure air column 3, when the high-pressure air column 3 is in the filling state, the annular air bag 302 is also in the filling state, the annular air bag 302 seals the opening part of the branch pipe, and the high-pressure air column 3 in the filling state is abutted against the inner wall of the branch pipe; since the opening of the main manifold faces the processing table 2, the gas flushed by the pressure relief valve is flushed from the opening of the main manifold to the processing table 2, the four-branch manifold 1 is fixed by the high-pressure gas column 3 and the gas flushed from the opening of the main manifold, and the height of the four-branch manifold 1 is determined by the high-pressure gas column 3 and the gas flushed from the opening of the main manifold.
