Multiple first reinforcing ribs 9 and second reinforcing ribs 10 are arranged between the multiple fixed plates 4, and the multiple first reinforcing ribs 9 and second reinforcing ribs 10 are arranged in a cross shape. At this time, the contact area can be increased again, and the strength of the device can be improved again. In the design of the grid bar 6, we adopt a parallel arrangement, which not only optimizes the distribution of current, but also improves the working efficiency of the battery. In order to further improve the strength of the entire device, we cleverly set the lifting assembly on the outer wall of the grid bar 6. The assembly is composed of multiple fixed plates 4, which are tightly fitted on the outer wall of the grid bar 6 and perfectly cooperate with the grid bar 6 through the internal clearance hole 8. Between two adjacent fixed plates 4, we also cleverly set multiple first reinforcing ribs 9 and second reinforcing ribs 10, which are distributed in a cross shape, like the warp and weft of steel, greatly enhancing the strength and stability of the grid bar 6;

A plurality of insertion slots 17 are carefully formed in one side of the rectangular plate 5, which are closely matched with the grid bars 6, ensuring the firm connection between the rectangular plate 5 and the grid bars 6. In order to meet the needs of different sizes of battery shells, we design an adjusting assembly on one side of the grid bar 6. The assembly is composed of two symmetrical side plates 18 arranged on one side of a fixed plate 4 close to the rectangular plate 5.
