Because the elastic force of the spring 202 is downward, the limit block 204 is installed on one side of the spring 202 through the baffle 203. It will move due to the elastic force of the spring 202, and the limit block 204 will enter the inner cavity of the limit plate 105, thereby fixing the limit plate 105 entering the interior of the shell 201. When the limit plate 105 needs to be disassembled, the pull ring 205 is pulled to allow the limit block 204 to be separated from the inner cavity of the limit plate 105, so that the limit plate 105 is disassembled and taken out. The sling 104 is fixedly installed in the limit plate 105. The plate 105 will be installed and disassembled along with the limit plate 105. After long-term use, the sling 104 is prone to damage. Quick disassembly can replace the damaged sling 104, which is more convenient to use. By starting the motor 302, the motor 302 will drive the threaded rod 303 to rotate during use, and the threaded sleeve 304 will move along with the rotation of the threaded rod 303. The connecting plate 305 will move along with the movement of the threaded sleeve 304. The positioning plate 307 is fixedly installed on the connecting plate 305 through the connecting rod 306. The positioning plate 307 will move along with the movement of the connecting plate 305. The positioning plate 307 is moved to contact the ground to position the device, thereby effectively preventing the device from shaking due to strong winds.
