[0028] The fixing device includes two fixing frames 13 , which are arranged opposite to each other and are both arranged in an arc shape. The bottom ends of the two fixing frames 13 are connected to the top end of the base 11 through connecting bolts 10 , and two fixing bolts 6 are respectively arranged on the two fixing frames 13 .

[0029] The fixing bolt 6 passes through the fixing frame 13 , and a fixing block 7 is provided at one end of the fixing bolt 6 away from the fixing frame 13 . The fixing block 7 is usually made of a flexible material that can change shape when compressed to adapt to the outer surface of the tank body and protect the outer shell of the tank body 1 .

[0030] A positioning groove for placing the tank body 1 is provided at the upper end of the base, which is usually set in a larger semicircular shape.
