A door frame 5 is fixedly connected to the top of the bottom plate 1. The door frame 5 is U-shaped, and a movable door panel is provided on the inner surface of the door frame 5, and a lock is provided on the movable door panel.

[0024] When the above-mentioned equipment is used, first open the movable door panel in the door frame 5, then flip the limit frame 2 upward, then place the new energy battery to be tested in the limit frame 2 and flip the limit frame 2 down to buckle the new energy battery. At this time, push the pull rod 404 to drive the limit block 403 to move backward, so that it blocks the top of the limit plate 3, so that the limit frame 2 cannot be flipped upward, and then rotate the bidirectional screw 406.
