A plurality of positioning holes 7 are opened on the opposite sides of the two positioning frames 6, and an annular groove 8 is opened at the center position of the opposite sides of the two positioning frames 6. A protective rod 9 is inserted between the positioning holes 7 between the two positioning frames 6, and two sliders 10 are sleeved on the periphery of two of the protective rods 9 on both sides, and an adjusting bolt 11 is movably installed inside the slider 10, and a pressure plate 12 is movably installed on the inner end of the adjusting bolt 11.

[0023] In this embodiment, the base 5 is fixedly installed on the top of the base plate 1 by bolt connection, and the two positioning frames 6 are symmetrically arranged. By fixing the two positioning frames 6 on the base plate 1 and then fixing the base plate 1 on the transport vehicle, the stability of the storage tank 2 is enhanced.

[0024] In this embodiment, the front and rear ends of the storage tank 2 are respectively located in two annular grooves 8 and are matched with each other. The two ends of the protective rod 9 are respectively located in the positioning holes 7 in the two positioning frames 6 and are snap-connected.

The adjusting bolt 11 passes through the interior of the slider 10 and is threadedly connected. The inner end of the adjusting bolt 11 passes through the interior of the pressure plate 12 and is movably connected through a bearing. The slider 10 slides to the corresponding support position, further enhancing the stability of the storage tank 2 and preventing shaking and sliding.
