[0026] In this embodiment, the buffer device includes two push rods 201 symmetrically arranged on both sides, a fixed sleeve 202 is arranged at the front end of the push rod 201, a connecting rod 209 is arranged between the two fixed sleeves 202, a buffer airbag 203 is arranged in the fixed sleeve 202, a fixed rod 204 is arranged in the buffer airbag 203, two limit plates 205 are symmetrically arranged at the upper and lower ends of the fixed rod 204, six first springs 206 are evenly arranged between the limit plates 205 and the fixed sleeve 202, a damping rod 207 is arranged on the upper limit plate 205, and a damping rod 207 is arranged on the damping rod 207. A second spring 208 is installed, and the buffer airbag 203 is annular in shape. The buffer airbag 203 is pasted together with the fixing rod 204. During the compaction process, the vibration generated by the fuselage 101 is transmitted to the fixing sleeves 202 at both ends of the connecting rod 209 through the push rod 201. At this time, the buffer airbag 203 on the fixing rod 204 will buffer the vibration in the horizontal direction, and the vibration in the vertical direction is transmitted to the limit plate 205 through the first spring 206, so that the damping rod 207 and the second spring 208 on the limit plate 205 buffer the vibration in the vertical direction;
