Lithium battery box with stable structure

The lithium battery box with the stable structure comprises a box body, first sliding grooves are formed in the two sides of the inner side wall of the box body respectively, two first sliding blocksare connected to the inner side walls of the two first sliding grooves respectively in a sliding mode, and a first plate body and a second plate body are fixedly connected to the adjacent sides of thefour first sliding blocks respectively. Two threaded rods are symmetrically and fixedly connected to one side of the first plate body, one ends of the two threaded rods penetrate through the second plate body, sleeves are in threaded connection with the outer side walls of the two threaded rods, and in the using process of the device, through the arrangement of the first sliding groove, the firstsliding block, the first plate body, the threaded rods and other components, the device is convenient to use. The lithium battery fixing device is simple in structure and convenient to adjust and adapt to lithium batteries of
