[0027] By setting the block 16 at the end of the connecting pipe 5 to be slidably connected with the inner wall of the mounting groove 6 and the groove 7 opened on the side wall of the mounting block 4, the block 16 can enter the interior of the fixing groove 8 at the inner end of the mounting groove 6. By rotating the connecting pipe 5, the block 16 can be rotated 180 degrees in the fixing groove 8, and the block 16 can be clamped by the fixing groove 8 to fix the connecting pipe 5. At this time, the direction of the interface 20 at the other end of the connecting pipe 5 is rotated 180 degrees, and the indicating block 18 faces downward. Conversely, when the indicating block 18 faces upward, the interface 20 faces downward.
