The two sliding blocks 612 can only move from both sides to the middle under the limitation of the first slide rail 613 and the first slider 614, thereby driving the clamping plates 611 on the top thereof to move from both sides to the middle. At this time, the two clamping plates 611 clamp the battery cells. Due to the symmetry of the two clamping plates 611, the battery cells can also be automatically aligned.

[0062] Step 6: The telescopic rod of the second cylinder of the pressure claw unlocking device 9 contracts, the two springs 715 rebound, the top plate 714 of the pressure claw assembly 7 descends, and the two guide rods 712 drive the pressure plate 711 to descend, and the pressure plate 711 presses the top of the battery cell;
