[0022] 3. The present invention is configured such that when the hanging basket accidentally falls, a plurality of buffer columns in the buffer mechanism at the bottom of the hanging basket first contact the base, and then squeeze the buffer spring after contacting the base. Under the elastic force of the buffer spring, a preliminary buffering effect is formed on the buffer cylinder, the buffer block and the hanging basket. At the same time, the buffer column squeezes the internal space of the buffer cylinder, so that the air inside the buffer cylinder is rushed into the buffer bag through the connecting pipe. After the buffer bag is inflated, it expands and pushes the bottom wall of the buffer cavity to bend downward. Therefore, when the bottom wall of the buffer cavity contacts the base, a further buffering effect is formed through the buffer bag, thereby improving the buffering protection effect on the hanging basket.

[0044] The operating principle of the present invention is now described as follows:

[0045] When working, the driving motor 5 works, and its output end drives the transmission belt 12 to move through the driving wheel 6, and the movement of the transmission belt 12 drives the tension wheel 8 and the transmission wheel 7 to rotate;

[0046] Under the elastic force of the tensioning spring 11, the tensioning slider 9 has a tendency to move away from the driving wheel 6 and the transmission wheel 7 in the sliding groove 10, thereby driving the tensioning wheel 8 to pull the transmission belt 12, so that the transmission belt 12 is always kept in a tensioned state, avoiding the safety hazard caused by the loosening of the transmission belt 12 due to long-term use;

[0047] When the transmission wheel 7 rotates, the winding wheel 15 is driven to rotate, thereby winding and unwinding the suspension rope 16, and controlling the up and down movement of the hanging basket 17;

[0049] When the hanging basket 17 falls unexpectedly, the multiple buffer columns 26 in the buffer mechanism at the bottom of the hanging basket 17 first contact the base 1, and the buffer columns 26 squeeze the buffer springs 27 after contacting the base 1. Under the elastic force of the buffer springs 27, a preliminary buffering effect is formed on the buffer tube 25, the buffer block 22 and the hanging basket 17; at the same time, when the buffer column 26 squeezes the buffer spring 27, it squeezes the internal space of the buffer tube 25, so that the air inside the buffer tube 25 is rushed into the buffer bag 30 through the connecting pipe 29. After the buffer bag 30 is inflated, it expands and pushes the bottom wall of the buffer cavity 23 to bend downward, so that the bottom wall of the buffer cavity 23 protrudes from the bottom of the buffer tube 25 and is flush with the bottom of the buffer column 26, so that the bottom wall of the buffer cavity 23 contacts the base 1, and a further buffering effect is formed through the buffer bag 30, thereby improving the buffering protection effect of the hanging basket 17.
