[0028] See also Figure 1 The driving motor 2 is installed on one side surface of the lifting body 1, and a power shaft 3 is installed at the output end of the driving motor 2. A stable bearing 4 connected to the power shaft 3 is installed on the side of the lifting body 1 close to the driving motor 2, and a rotating shaft 5 is installed on the other side of the lifting body 1. The lifting disc 15 is fixed on the outer surfaces of the power shaft 3 and the rotating shaft 5.

[0029] Based on the above embodiment 1, please refer to Figure 5 , each of the bottom surfaces of the lifting plates 15 is distributed with two disassembly bolts 7, each of the disassembly bolts 7 is movably inserted into the inner wall of the lifting plate 15, and the disassembly bolts 7 extend from one side surface of the lifting plate 15 to one side surface of the inner wall, and the disassembly bolts 7 pass through the connecting block 6 and the end is threadedly connected with a nut 8, and the connecting block 6 is connected to the lifting plate 15 through the disassembly bolts 7.

[0030] The working principle and use process of the present invention are as follows: when the hoist is needed, the driving motor 2 is started. When the driving motor 2 is started, the power shaft 3 installed on one side surface thereof will be electrically rotated, and the outer surface of the power shaft 3 is movably connected to the inner wall of the stable bearing 4. Therefore, the rotating power shaft 3 will rotate on the inner wall of the stable bearing 4, so that the stable bearing 4 is a stably fixed rotating power shaft 3, and a lifting disk 15 is installed on the outer surface of the power shaft 3. Therefore, the rotating power shaft 3 will drive the lifting disk 15 to rotate, and a lifting chain 11 is installed on the outer surface of the lifting disk 15, and a connecting block 6 is installed on the outer surface of the lifting disk 15, and an anti-slip block 9 is installed on the top surface of the connecting block 6. When the lifting disk 15 rotates and drives When the anti-slip block 9 installed on its outer surface rotates, the outer surface of the anti-slip block 9 will contact the inner wall of the lifting chain 11, and the rotating lifting disc 15 will drive the lifting chain 11 to rotate and move through the anti-slip block 9. Because the anti-slip block 9 has a certain curvature, when the anti-slip block 9 contacts the inner wall of the lifting chain 11, it will hook the inner wall of the lifting chain 11, thereby achieving the anti-slip function, and because the outer surface of the lifting disc 15 is installed with an anti-slip plate 10, when the lifting disc 15 rotates, the anti-slip plate 10 will hook the anti-slip rod 14 installed on one side surface of the mounting block 12, and through the rotation of the lifting disc 15, the anti-slip plate 10 will further drive the lifting chain 11 to rotate through contact with the anti-slip rod 14, thereby achieving the advantage of double anti-slip.

[0031] When the connecting block 6 is damaged during the use of the hoist, it is only necessary to rotate the nut 8 installed on the outer surface of the disassembly bolt 7 to separate the nut 8 and the disassembly bolt 7. When the nut 8 is removed, hold the anti-falling block 9 and push it outward. At this time, the connecting block 6 and the anti-falling block 9 will fall off from one side surface of the lifting plate 15, thereby realizing quick replacement and disassembly of the connecting block 6.
