[0029] Working principle: When the main beam body 11 needs to be hoisted and assembled, after the angle of the boom 102 is adjusted, the mounting plate 16 is in a horizontal state under the action of gravity, and then the first electromagnet 505 is energized. After the first electromagnet 505 is energized, it attracts the first iron block 504, so that the first moving block 403 and the limiting plate 404 move upward.

When the sliding rod 706 abuts against the first inclined surface 704, the two clamping plates 17 are pushed to move away from each other, and at the same time, the second spring 603 is compressed, thereby loosening the main beam body 11; Furthermore, when the second moving block 702 moves, it drives the third connecting plate 901 to move synchronously. When the upper end of the push rod 904 slides downward along the second inclined surface 906, it can push the moving ring 903 to move downward. At the same time, the fourth spring 1002 is compressed and pushes the safety card 105 to rotate downward and open. When the side wall of the through hole 902 abuts against the lifting rope 103, the hook 104 can be pulled off from the hook 1101, thereby realizing the automatic unhooking operation of the hook 104, which is more convenient, quick, safe and reliable to use.
