[0018] The present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0019] Please refer to Figures 1 to 5, in this embodiment, a hoisting device for an excavator is provided, including a housing 1 and a hook 2. On the inner top of the housing 1, fixing plates 25 are symmetrically installed front and back. The inner ends of the fixing plates 25 are installed with moving seats 11 in a sliding fit manner. The upper end surface of the moving seat 11 is installed with a first spring rod 12, the upper end surface of the first spring rod 12 is installed with a connecting column 13, and the right end surface of the moving seat 11 is installed with a second spring rod 14. A first through hole 15 is opened on the right end surface of the housing 1, and a second through hole is opened on the outer end of the hook 2. During work, when the hook 2 hoists, the connecting column 13 drives the moving seat 11 to move upward, and the second spring rod 14 moves upward and sequentially passes through the first through hole 15 and the second through hole, so as to seal the hook and avoid the phenomenon of the excavator rope slipping, ensuring the safety of the excavator operation.

[0020] A first magnet 16 is installed on the right end surface of the second spring rod 14, a sleeve is installed on the right end surface of the hook 2, a second magnet 17 is installed on the inner end of the sleeve, a fixing hole is opened on the right end surface of the sleeve, and a push rod 18 is installed in the fixing hole in a sliding fit manner. A placement groove is opened on the right end surface of the hook 2, an adjusting spring 19 is installed at the bottom of the placement groove, an adjusting slider is installed on the upper end surface of the adjusting spring 19, and a limiting frame 21 is installed on the right end surface of the adjusting slider. During work, when the second spring rod 14 is inserted into the second through hole, the first magnet 16 and the second magnet 17 attract each other, so as to limit the second spring rod 14 and avoid the left and right shaking of the second spring rod 14. The limiting frame 21 limits the push rod 18. Press the limiting frame 21 downward to push the push rod 18, and the push rod 18 squeezes the first magnet 16, so that the second magnet 17 is separated from the first magnet 16, facilitating the separation of the first spring rod 12.
