The first connecting rod 24 and the third connecting rod 28 drive the second connecting rod 26 and the fourth connecting rod 30 to rotate respectively. The second connecting rod 26 and the fourth connecting rod 30 drive the first anti-falling insertion rod 27 and the second anti-falling insertion rod 31 to move closer to each other. The first anti-falling insertion rod 27 and the second anti-falling insertion rod 31 are respectively disengaged from the first ratchet rack 13 and the second ratchet rack 14 on the anti-falling frame 12. When a failure occurs to the equipment or the first lifting rope 10 breaks, the reset spring 20 on the reset elastic component 11 drives the mounting block 19 to move downward by its own elastic force. The mounting block 19 drives the mounting frame 21 to move downward. The mounting frame 21 drives the first anti-falling insertion rod 27 and the second anti-falling insertion rod 31 to move away from each other respectively through the first connecting rod 24, the second connecting rod 26, the third connecting rod 28 and the fourth connecting rod 30, so that the first anti-falling insertion rod 27 and the second anti-falling insertion rod 31 move to engage with the first ratchet rack 13 and the second ratchet rack 14 on the anti-falling frame 12, thereby preventing the whole device from falling.
