[0047] By pushing the outer connecting shaft 38 and the rotating handle 39 toward the inside of the control box 31, the bearing 30 extruded and fitted on the outer side of the outer connecting shaft 38 will carry the bearing seat 301 and move along the slide rail 302 toward the control box 31, wherein the outer side of the outer connecting shaft 38 is connected to the No. 1 gear 303, so the No. 1 gear 303 will move inward along the outer side of the No. 2 gear 304, and the inner end of the outer connecting shaft 38 is connected to the five-flower piece 35, so the five-flower piece 35 will be embedded in the machine shaft sleeve 34, and the machine shaft sleeve 34 is fixedly connected to the output shaft of the servo motor 33, so the outer connecting shaft 38 will be connected to the output shaft of the servo motor 33 When the servo motor 33 is started, the shaft sleeve 34 connected to its output shaft will rotate with the five-flowered piece 35, so that the outer connecting shaft 38 will rotate in the positive direction, and then the No. 1 gear 303 connected to the outer side of the outer connecting shaft 38 will mesh with the No. 2 gear 304, wherein the center part of the No. 2 gear 304 is connected to the serial shaft 305, and the center part of the outer side of the serial shaft 305 is connected to the rope roller 306, so the rope roller 306 will extend the suspension rope 23 connected to its outer side outward, and finally the hook 20 fixedly connected to the bottom end of the suspension rope 23 will move downward and put the emergency supplies on.

[0048] The outer side of the hanging rope 23 is squeezed and adapted with an anti-sway piece 2015, and the outer side of the anti-sway piece 2015 is connected to the spring rod 2014. Therefore, when the hanging rope 23 is attacked by wind, it will sway left and right. However, under the elastic force of the spring rod 2014, the anti-sway piece 2015 will prevent the hanging rope 23 from swaying, so as to prevent the hanging rope 23 from swaying too violently and causing the emergency supplies to fall off.

[0049] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
