[0035] Please refer to Figure 3 The buffer assembly 3 in the embodiment comprises a threaded telescopic rod 301, a buffer plate 302, a buffer spring 303 and two stabilizing rods 304. The threaded telescopic rod 301 is rotationally connected with the protective box 2. The threaded telescopic rod 301 comprises an extension block rotationally connected with the protective box 2.

When the protection box 2 is impacted, the threaded telescopic rod 301 moves in the inside of the buffer plate 302 due to the impact force, and then the threaded telescopic rod 301 extrudes the buffer spring 303, so that the buffer spring 303 is deformed to buffer the impact force, thereby effectively reducing the impact of the impact force on the double-walled liquid storage tank 4. The buffer plate 302 is attached to the double-walled liquid storage tank 4, which can assist in supporting the double-walled liquid storage tank 4, so that the double-walled liquid storage tank 4 is not easy to shake, thereby improving the stability of the double-walled liquid storage tank 4.
