Drive the curved rod 10 through the rotating shaft 21 to push or pull the clamping plate 2 to slide under the limitation of the limiting rod 3, achieving the effect of quickly fixing and disassembling the sling sleeve 20. During use, by dialing the pawl 7 out of the inner wall of the ratchet 6, the ratchet 6 can be quickly unlocked during use, thus achieving the effect of quickly disassembling the sling sleeve 20. During use, the limiting effect achieved by the sliding of the clamping plate 2 on the outer wall of the limiting rod 3 allows the clamping plate 2 to maintain stability when fixed on the outer wall of the connecting support rod 1, and the outer shell 4 plays a limiting role to prevent falling off. During use, drive the gear 16 to rotate on the inner wall of the protective shell 14 by the motor 15. During use, drive the rack 17 to slide on the inner walls of the protective shell 14 and the limiting block 18 through the gear 16, and the limiting effect achieved by the limiting groove 19 can drive the connecting support rod 1 to slide on the upper surface of the limiting slide plate 11. During use, when the rack 17 drives the connecting support rod 1 to move, the angle of the connecting support rod 1 can be adjusted according to different lifted items, thus achieving the effect of quickly adjusting the lifting distance during use. During use, the stability when lifting items can be further increased. During use, the sling not only achieves the effect of quickly fixing and disassembling the sling sleeve 20 by driving the connecting plate 9 and the rotating shaft 21 to rotate by the handle 5, driving the curved rod 10 through the rotating shaft 21 to push or pull the clamping plate 2 to slide under the limitation of the limiting rod 3, but also has the effect of driving the connecting support rod 1 to slide on the upper surface of the hanger 12 under the limitation of the limiting slide plate 11 through the rack 17, adjusting the position of the sling sleeve 20 according to the size of the item when lifting the item, so as to stably lift items of different sizes and maintain stability.
