Then, after reaching the specified position, the pull plate 211 is released, and then the pull plate 211 is restored to its original position under the action of the spring 212, and then the pull plate 211 is The convex surface is tightly attached to the back side of the mounting plate 210, and then the pull plate 211 pressurizes and fixes the mounting plate 1 203 and the mounting plate 210, so as to achieve the effect of preventing the bracket plate 201 from falling off in the working state. Finally, the pull rod 303 is pulled inward by hand, and the connecting rod 304 is moved by the movement of the pull rod 303, and then the block 301 is driven to slide on the surface of the guide rod 302, and then the spring 2 305 is compressed. After the insulating shells 101 on the front and right sides are installed, the pull rod 303 is released, and then the block 301 is restored to its original position under the action of the spring 2 305, and then the adjacent insulating shells 101 are connected and fixed, so as to prevent the adjacent insulating shells 101 from being disconnected during the operation of the battery pack. At the same time, through the setting of the round block 306, the block 301 is limited during the movement to prevent the block 301 from falling off the surface of the guide rod 302 during the movement.
