The traction end of the suspension rope 21 is connected to the mobile vehicle 11, and the anti-sway device is installed on the hook assembly 22; the anti-sway device includes a number of supporting cross plates 3 and a release rope 4; the two ends of the supporting cross plates 3 are connected to rings 31 and the rings 31 are mounted on the outside of the suspension rope 21; the release rope 4 is connected to a number of supporting cross plates 3 and the two ends of the release rope 4 are respectively connected to the lower surface of the mobile vehicle 11 and the upper part of the hook assembly 22; please refer to Figure 1 As shown, the hook assembly 22 generally includes a frame for mounting the hook and the transmission pulley, as well as a hook, both of which are prior art. The lower end of the release rope 4 is connected to the upper end of the frame. Several support cross plates 3 are stacked on the upper end surface of the frame before being unfolded. In practice, a certain length of the release rope 4 between two adjacent support cross plates 3 is reserved as needed, and it is appropriate to effectively limit the maximum spacing distance between the two ropes 21 when it is wrapped. Specifically, a rope hole 32 is provided at the center of the support cross plate 3; the rope 21 passes through the rope hole 32 and the rope 21 is fastened to the support cross plate 3 by a fastening screw 321. In actual use, the rope 21 is fastened by the fastening screw 321. At the same time, the spacing between the ropes 21 of two adjacent support cross plates 3 can be adjusted by unscrewing and tightening the fastening screw 321 to adapt to actual conditions, which is convenient and effective.

[0027] When this embodiment is actually used, the spacing between the suspension ropes 21 between adjacent support cross plates 3 is first set by tightening the screws 321 before use; when the hook assembly 22 is released downward, the support cross plates 3 are sequentially unfolded from top to bottom, thereby achieving stable support for the two suspension ropes 21 without affecting the release and retraction of the suspension ropes 21 themselves, avoiding entanglement of the two suspension ropes 21 due to swinging, being convenient, practical, and improving safety.

When the hanging rope 21 is gathered, it can be stored in the rope receiving groove 322. That is, the rope receiving groove 322 facilitates the storage of the hanging rope, thereby improving the stability of the stacking of the support cross plates 3. Furthermore, two magnets 33 are embedded in the lower bottom surface of the support cross plate 3, and the two magnets 33 are symmetrical about the rope receiving groove 322. The magnets 33 on the upper and lower support cross plates 3 are attracted to each other, thereby ensuring the stability of the stacking of the support cross plates 3.
