When the slider 2 2014 contacts the slider 3 2016, it continues to rise, pushing the slider 3 2016 upward. At this time, the spring 1 206 is compressed, driving the arc clamping plate 204 to rise through the connecting frame 205, and then the hanging basket rope is hung inside the hook 5, and the hanging basket rope is located directly below the arc clamping plate 204, and then the clamping plate 203 is released. At this time, the clamping plate 203 rotates under the elastic force of the spring 2012 and is clamped in the clamping groove 2019 to limit the hanging basket rope. At the same time, the slider 2014 descends to release the restriction effect on the slider 3 2016. At this time, the arc clamping plate 204 moves downward under the elastic force of the spring 1 206 to clamp the hanging basket rope, further limit the hanging basket rope, and finally prevent the hanging basket rope from slipping.

[0032] Embodiment 3, on the basis of embodiment 1, the locking mechanism 3 includes a mounting frame 301 fixed to the outside of the hook 5, the outside of the mounting frame 301 is symmetrically fixedly connected with two guide columns 3012, the ends of the two guide columns 3012 away from the mounting frame 301 are fixedly connected with side blocks 3011, the outsides of the two guide columns 3012 are movably sleeved with guide blocks 307, the two guide blocks 307 are respectively abutted against the two side blocks 3011, the bottoms of the two guide blocks 307 are fixedly connected with plug rods 308, the slider 208 is located between the two plug rods 308, the outside of the slider 208 is symmetrically provided with two plug holes 309, the inner diameter values ​​of the two plug holes 309 are equal to the outer diameter values ​​of the two plug rods 308, the top of the mounting frame 301 is fixedly connected with a U-shaped round rod 305, the outside of the U-shaped round rod 305 is movably sleeved with a lifting plate 303, the lifting plate 303 A driving assembly 302 is provided at the bottom, and two movable rods 306 are symmetrically rotatably connected to the outer side of the lifting plate 303, and one end of the two movable rods 306 away from the lifting plate 303 is rotatably connected to two guide blocks 307 respectively.
