[0023] like Figure 4 As shown, when the lithium battery pack is pressed against one side of the limiting plate 2, the lithium battery pack first peels off the plastic on the upper and lower sides. After the peeling is completed, the lithium battery pack is rotated 180° so that the plastic originally located on one side of the push plate 403 is switched to the side close to the limiting plate 2 for peeling. At this time, by setting an auxiliary separation structure 6, the top of the lithium battery pack can be pressed tightly to prevent the push knife 503 from being able to position and squeeze the plastic on the other side after the plastics on both sides are peeled off.
