[0039] The clamping assembly 300 comprises rubber pad two 310 arranged on the side of the damping assembly 200, the side of the rubber pad two 310 is screw-connected with a limiting block 320, the top of the limiting block 320 is tightly welded with a support plate one 330, the top of the support plate one 330 is tightly welded with a clamp one 340, the top of the clamp one 340 is tightly welded with a support plate two 350, the top of the support plate two 350 is tightly welded with a clamp three 370, the side of the clamp one 340 is clamped with a clamp four 380.

Then, the clamping assembly 300 tightly fixes the tank body 500 through the hoop one 340, hoop three 370, and hoop four 380, and the rubber pad three 360 increases the friction and protection effect. The fixing pin assembly 400 uses the knob 420 to press down and rotate the rotating column 430 through the cooperation of the L-shaped clamping strip and the clamping seat, drives the clamping block 450 to be clamped into the clamping block one of the hoop one 340, and the cross slot of the fixing piece 460 is locked, to ensure that the tank body 500 is stable and safe. Then, the damping bottom plate 210, damping spring 220, and damping top plate 230 in the damping assembly 200 cooperate with the rubber pad one 240 to effectively absorb and disperse the shock generated by the external impact, protecting the tank body 500 from damage.
