[0044] By providing the connecting plate 406, the mounting bracket 407, the liquid injection gun 408, the stud 4081 and the fastening nut 4082, the utility model has the advantages that the liquid injection gun 408 can be installed or disassembled separately, and the damaged liquid injection gun 408 can be replaced separately, with higher efficiency, and solves the problem that multiple liquid injection guns 408 are fixed together and cannot be disassembled separately, and it is inconvenient to disassemble and replace a single damaged liquid injection gun 408.

[0045] Specifically, a conveyor body 2 is arranged below the liquid injection area frame of the battery liquid injection machine body 1, and the conveyor body 2 is selected and used by technical personnel in this field according to the actual situation; two holding frames 3 are symmetrically fixed on the top side of the conveyor body 2.
