Moreover, the top plates 510 provided in the clamping mechanism 5 limit the upper part of the clamping block 502 to prevent the clamping block 502 and the suspension strap 4 from moving in the clamping seat 501, ensuring the stability of the hanging device for installing the hanging basket.

[0027] In this embodiment, refer to Figure 2 、 Figure 3 and Figure 4As shown in the figure, a bidirectional lead screw 504 is provided inside the card seat 501.

Subsequently, start the motor inside the card seat 501 to drive the second bevel gear 506 to rotate, and cooperate with the first bevel gear 505 to make the bidirectional lead screw 504 rotate. Under the limiting effect of the card seat 501, the two sets of positioning rods 503 move synchronously until the two sets of positioning rods 503 are both clamped with the clamping block 502, realizing the preliminary fixation of the clamping block 502. At the same time, start the motor to drive the second gear 513 to rotate, and cooperate with the external engaging teeth 508 to drive the installation ring 507 to rotate. Under the action of the internal meshing teeth in the installation ring 507, the first gear 512 is pushed, so that the first gear 512 drives the installation shaft 511 and the top plate 510 to rotate, and multiple top plates 510 are closed synchronously to limit the upper part of the clamping block 502, so that the clamping block 502 cannot be displaced, and the upper end of the sling 4 is stably fixed to the cross beam 3.

[0028] In this embodiment, refer to Figure 5 and Figure 6As shown in the figure, the hoisting mechanism 6 includes a lifting ring 601 fixedly installed at the bottom end of the sling 4. The lifting ring 601 is rotatably installed with a snap ring 602 through a rotating shaft. A positioning block 603 is provided on the snap ring 602, and the positioning block 603 is movably clamped with the lifting ring 601. Two groups of symmetrically distributed clamping rods 604 are arranged in the lifting ring 601. Both groups of clamping rods 604 are slidably connected with the lifting ring 601, and both groups of clamping rods 604 are movably clamped with the positioning block 603. A compression spring 605 and a stop block 606 are sleeved on the clamping rod 604. Two ends of the compression spring 605 are respectively fixedly connected with the stop block 606 and the lifting ring 601. A rack 607 is fixedly installed on the clamping rod 604. A driving wheel 608 is arranged in the lifting ring 601, and the driving wheel 608 is respectively meshed with the two groups of racks 607. The driving wheel 608 is rotatably connected with the lifting ring 601 through a rotating rod 609. A torsion spring 610 is sleeved on the rotating rod 609, and two ends of the torsion spring 610 are respectively fixedly connected with the rotating rod 609 and the lifting ring 601. When the snap ring 602 below the sling 4 is separated from the lifting ring 601, the snap ring 602 and the lifting ring 601 are passed through the hanging basket, and the snap ring 602 is rotated so that the positioning block 603 is clamped with the lifting ring 601. Before the positioning block 603 is clamped with the lifting ring 601, the rotating rod 609 is rotated to drive the driving wheel 608 to rotate. When the rotating rod 609 rotates, the torsion spring 610 is twisted synchronously. The two groups of racks 607 slide outwards synchronously, driving the clamping rods 604 and the stop blocks 606 to slide synchronously, compressing the compression spring 605. After the positioning block 603 is clamped with the lifting ring 601, the rotating rod 609 is released. Under the action of the torsion spring 610 and the compression spring 605, the two groups of gears and the two groups of clamping rods 604 slide inwards synchronously and are both clamped with the positioning block 603, realizing the rapid closing between the lifting ring 601 and the snap ring 602, and realizing the rapid connection between the sling 4 and the hanging basket. A large amount of time for disassembling and assembling connecting parts is saved during the process, and the working process is accelerated.

[0029] During the operation of this embodiment, the sling 4 is passed through the card seat 501 on the cross beam 3, and the clamping block 502 is located inside the card seat 501. Subsequently, the motor inside the card seat 501 is started to drive the second bevel gear 506 to rotate, which, in cooperation with the first bevel gear 505, causes the bidirectional lead screw 504 to rotate. Under the limiting effect of the card seat 501, the two positioning rods 503 move synchronously until both of the two positioning rods 503 are clamped with the clamping block 502, realizing the preliminary fixation of the clamping block 502. At the same time, the motor is started to drive the second gear 513 to rotate, which, in cooperation with the external teeth 508, drives the mounting ring 507 to rotate. Under the action of the internal meshing teeth in the mounting ring 507, the first gear 512 is pushed, causing the first gear 512 to drive the mounting shaft 511 and the top plate 510 to rotate. Multiple top plates 510 close synchronously to limit the upper part of the clamping block 502, making the clamping block 502 unable to displace, and the upper end of the sling 4 is stably fixed to the cross beam 3. The installation process is fast and convenient. Subsequently, the clamping ring 602 below the sling 4 is separated from the hanging ring 601, the clamping ring 602 and the hanging ring 601 are passed through the hanging basket, and the clamping ring 602 is rotated so that the positioning block 603 is clamped with the hanging ring 601. Before the positioning block 603 is clamped with the hanging ring 601, the rotating rod 609 is rotated to drive the driving wheel 608 to rotate. When the rotating rod 609 rotates, the torsion spring 610 twists synchronously, and the two racks 607 slide outwards synchronously, driving the clamping rod 604 and the blocking block 606 to slide synchronously, compressing the compression spring 605. After the positioning block 603 is clamped with the hanging ring 601, the rotating rod 609 is released. Under the action of the torsion spring 610 and the compression spring 605, the two gears and the two clamping rods 604 slide inwards synchronously and are both clamped with the positioning block 603, realizing the rapid closing between the hanging ring 601 and the clamping ring 602 and the rapid connection between the sling 4 and the hanging basket. A large amount of time for disassembling and assembling connectors is saved during the process, accelerating the work progress.
