[0020] Rotating assembly includes rotating sleeve 6 and worm 63, rotating sleeve 6 is movably installed in the periphery of the bottom of rotating plate 3, rotating sleeve 6 bottom inner wall is rotatably connected with the outer lateral wall of fixed table 2, worm wheel 61 is fixed in the periphery of the bottom of rotating sleeve 6, worm 63 is rotatably connected above pedestal 1 and position rotating sleeve 6 outer side, worm 63 is engaged with worm wheel 61, lifting block 65 is fixed in the upper end inner wall of rotating sleeve 6, lifting groove 34 is opened in the outer lateral wall of rotating plate 3 and corresponding position of lifting block 65, lifting block 65 is slidably connected in lifting groove 34, a pair of mounting bracket 62 is fixed on pedestal 1, worm 63 is rotatably connected between mounting bracket 62, drive motor 64 that drives worm 63 to rotate is fixed on the outer side of mounting bracket 62.

[0021] In this embodiment, first, the whole device is connected to an external power supply, then the two pipes are fixed on the corresponding base 1 respectively, the pipes are inserted into the fixing sleeve 5, and the locking bolt 51 is used for locking and fixing. At this time, if the height deviation of the butt joint position between the pipes appears, the telescopic cylinder 21 can be driven to drive the rotating plate 3 to drive up and down, thereby realizing the height calibration of the pipes. If the horizontal position is misaligned, the sliding block 4 can be used for sliding to calibrate horizontally. Secondly, when the horizontal angle is misaligned, the rotating sleeve 6 can be used to drive the rotating plate 3 to rotate, and finally the horizontal angle calibration is realized.
