[0023] In actual application of this embodiment, the lifting and winding device 500 works and releases the lifting rope part 510.

The lifting and winding device 500 works and reels the lifting rope part 510, so that the two clamping and lifting mechanisms 400 lift the pole body 300 from both ends. At this time, since the lateral pushing part applies axial force to the end of the pole body 300, if the distances between the positions of the two clamping and lifting mechanisms 400 clamping the pole body 300 and the ends thereof are different, the axial forces applied to the two ends of the pole body 300 are different, and the pole body 300 will move axially relative to the two clamping and lifting mechanisms 400 until the pole body 300 is lifted.

When the arc-shaped clamping plates 440 clamp the pole body 300, the outer wall of the pole body 300 rolls with the ball part 441, so that the arc-shaped clamping plates 440 will not limit the axial movement of the pole body 300, so that the position of the pole body 300 can be adjusted by the lateral pushing part.
