[0021] Preferably, the end edge of the threaded bolt 4 is provided with a rounded corner, which facilitates positioning and installation.
[0022] Embodiment two, please refer to Figure 3 The embodiment is substantially the same as embodiment one, and the difference lies in that a cylindrical quick-release bolt 41 is arranged in the fixing hole, a ball groove is formed in the side surface of the cylindrical quick-release bolt 41, a ball 5 is arranged in the ball groove in a rolling manner, a ball spring is arranged between the ball 5 and the ball groove, the horizontal rotor body 1 and the hanging basket 2 are fixed by direct insertion, and the disassembly and assembly are convenient and simple to operate.
[0023] The inner side surface of the hanging basket fixing piece 3 is provided with an annular groove or a spherical groove corresponding to the ball 5, the annular groove is suitable for the case that the hanging basket 2 can rotate, and the spherical groove is suitable for the case that the hanging basket 2 is relatively fixed. The force required when the cylindrical quick-release bolt 41 is pulled out is greater than 2.5 N, so as to avoid the cylindrical quick-release bolt 41 from falling off during rotation of the rotor.
[0024] Preferably, the end of the cylindrical quick-release pin 41 away from the ball 5 is provided with a stopper 6, and the stopper 6 is provided with a pull ring 7, so that the cylindrical quick-release pin 41 can be conveniently pulled out through the pull ring 7. The pull ring 7 can be rotating or hinged on the stopper 6, and can be rotated and stored when not in use to avoid affecting the rotation of the rotor.
[0025] Embodiment three, please refer to Figure 4 , this embodiment is substantially the same as embodiment two, the difference is that the fixing hole is provided with a square quick-release pin 42, the side surface of the square quick-release pin 42 is provided with a ball groove, the ball groove is provided with a ball 5, and the ball 5 is provided with a ball spring between the ball groove and the ball groove.

Compared with embodiment two, the horizontal rotor body 1 and the hanging basket 2 are fixed by the square quick-release pin 42, so that the hanging basket 2 does not rotate when the horizontal rotor body 1 rotates, and is more stable when separated.
[0026] Preferably, the end of the cylindrical quick-release pin 41 away from the ball 5 is provided with a stopper 6, and the stopper 6 is provided with a pull ring 7, so that the cylindrical quick-release pin 41 can be conveniently pulled out through the pull ring 7. The pull ring 7 can be rotating or hinged on the stopper 6, and can be rotated and stored when not in use to avoid affecting the rotation of the rotor.
[0027] Embodiment four, please refer to Figure 5 , this embodiment is substantially the same as embodiment one, the difference is that the fixing hole is provided with a cuboid-shaped pressing quick-release pin 43, the upper surface of the pressing quick-release pin 43 is provided with an inclined groove 8, the inner surface of the inclined groove 8 is inclined downward to the direction of the hanging basket 2, the upper surface of the horizontal rotor body 1 is provided with a sliding groove corresponding to the inclined groove 8, and the sliding groove is provided with a pressing block 11, the lower surface of the pressing block 11 is a slope matched with the inner surface of the inclined groove 8. When the pressing block 11 is pressed downward, the inclined surface and the inclined groove 8 can drive the pressing quick-release pin 43 to move outward, so as to be separated from the fixing hole on the hanging basket fixing piece 3, which is convenient to take down the hanging basket fixing piece 3, easy to operate and convenient to use.
[0028] A first retaining ring 9 is fixedly installed on the outer surface of the quick-release pin 43. A first spring 10 is installed between the first retaining ring 9 and the inner side of the horizontal rotor body 1. The first spring 10 is sleeved on the outer side of the quick-release pin 43. When the first spring 10 is not subjected to external force, it tightens the first retaining ring 9, so that the quick-release pin 43 is positioned in the fixing hole of the hanging basket fixing component 3, maintaining the fixation of the hanging basket 2. When the pressing block 11 moves down, it presses the quick-release pin 43 to move outward, releasing the hanging basket 2. At this time, the first spring 10 is stretched and has a tendency to rebound. After removing the hanging basket 2, the pressing block 11 is released, and the quick-release pin 43 returns to its original position under the elastic force of the first spring 10. That is, each time the hanging basket 2 is installed and removed, the quick-release pin 43 needs to be moved to the outside by the pressing block 11 and then released.
[0029] By using the quick-release pin 43 of this embodiment, multiple pressing blocks 11 can be pressed simultaneously, causing multiple quick-release pins 43 to release the fixing of the hanging basket 2 at the same time, making it convenient to quickly remove multiple hanging baskets 2 and improving work efficiency.
[0030] Optionally, a second fixing ring 12 is fixedly provided on the outer surface of the pressing block 11. A second spring 13 is provided between the second fixing ring 12 and the inner side of the horizontal rotor body 1. The second spring 13 is sleeved on the outer side of the pressing block 11. When there is no external force, the second spring 13 is in an extended state. The second fixing ring 12 pushes the pressing block 11 to a high position so that it does not contact the quick-release pin 43, thus avoiding affecting the fixation of the quick-release pin 43 to the hanging basket 2. When a downward force is applied to the pressing block 11, the pressing block 11 and the second fixing ring 12 slide downward in the groove, pressing the quick-release pin 43 to move while pressing the second spring 13. After the hanging basket 2 is removed, the pressing block 11 is released, and the second spring 13 returns to its original position, causing the pressing block 11 and the second fixing ring 12 to move upward back to their original position.
