A pulley body 3 is provided, and a connecting column 6 is passed through the interior of the pulley body 3. A card slot 60 is provided at the top right side of the connecting column 6. A fixed plate 7 is engaged with the interior of the card slot 60, and a threaded buckle 8 is connected to the surface of the fixed plate 7. A square groove 4 is provided inside the fixed body 1, and a card plate 40 is provided inside the square groove 4. A movable plate 42 is installed at the bottom of the card plate 40, and a spring 41 is provided inside the square groove 4. A movable groove 51 is provided inside the fixed body 1, and a rotating column 5 is movably connected to the surface of the movable groove 51. A rotating plate 50 is provided on the side of the rotating column 5, and a column groove 52 is provided on the surface of the fixed body 1.

[0019] In order to facilitate the rotation of the hanging plate 2 out of the long plate groove 12, in this embodiment, preferably, the right side of the hanging plate 2 and the long plate groove 12 correspond to and fit with each other.

[0020] In order to facilitate the locking and fixing of the fixing plate 7 to the connecting column 6, in this embodiment, preferably, the connecting groove 10 is connected to the first connecting hole 11, the long plate groove 12 is connected to the second connecting hole 14, and the connecting column 6 passes through the first connecting hole 11, the interior of the pulley body 3 and the interior of the second connecting hole 14 in sequence. The block groove 13 is arranged inside the fixing plate 7, and the bottom of the fixing plate 7 is locked and connected with the card groove 60.

[0021] In order to facilitate the locking and fixing of the right end of the locking plate 40 to the hanging plate 2 due to the thrust of the spring 41, in this embodiment, preferably, one end of the spring 41 is fixedly connected to the left side of the square groove 4, and the other end of the spring 41 is fixedly connected to the inside of the locking plate 40, the square groove 4 is connected to the long plate groove 12, and the right end of the locking plate 40 corresponds to and fits with the locking groove 21.
