[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] During operation, first adjust the length of the adjusting column 411 when adjusting the relative misalignment between the hook 1 and the pipe, so that the adjusting column 411 does not completely cover all the holes when the adjusting column 411 and the positioning column 3 are inserted into the aligned pipe holes. First pull the limiting column 51, and the pulling of the limiting column 51 causes the moving rod 54 to slide outward. The sliding of the moving rod 54 on one side causes the moving rod 54 on the other side to slide to the other side through the synchronization component 53, and the contact block 55 is separated from the surface of the operating rod 421. At this time, the operating rod 421 can be rotated, and the rotation of the operating rod 421 causes the connecting belt 422 to be wound, thereby pulling the connecting rod 423 to move upward, causing the adjusting rod 421 to rotate. The rod 413 moves to the right. After the position adjustment of the adjusting rod 413 is completed, the limiting column 51 is pressed to make the contact block 55 contact with the operating rod 421 to limit the rotation of the operating rod 421. When adjusting the misalignment, the positioning column 3 is inserted into the hole of the pipe on one side, and the surface of the adjusting bolt 2 contacts with the pipe on the other side. The adjusting bolt 2 is rotated to change the height between the pipes. When the pipes are flush, the adjusting column 411 will bounce into the pipe on the other side under the action of the fixing spring 412 to fix the height. At this time, the screw is screwed in from the position of the pipe on the other side. The rotation of the screw will prompt the adjusting column 411 to move backward continuously. When the screw passes through the two holes, the misalignment adjustment hook 1 can be removed.
