Storage battery fixing structure

The invention belongs to the field of underground operation equipment, and particularly relates to a storage battery fixing structure. According to the specific technical scheme, first fixing assemblies are arranged on the two adjacent side walls of the box body, the box cover is connected with the box body through second fixing assemblies, a first through hole is formed in the side wall of the box body, each first fixing assembly comprises a piston rod, one end of each piston rod penetrates through the corresponding first through hole, extends into the box body and is connected with a syringe, and the syringe is connected with the box cover. A piston hole is formed in the syringe in the axial direction, threads are arranged in the piston hole, the piston rod is in threaded connection with the piston hole, a vacuum suction cup is arranged at the end, away from the piston rod, of the syringe, and the vacuum suction cup is communicated with the piston hole. In the rotating process of the piston rod, the storage
