When lifting the battery main body 1, it is necessary to ensure that the two groups of card blocks 38 are inserted into the card slot 24. At this time, turn the knob 29, and the knob 29 and the fixing shell 26 The internal worm gear 31 is connected together, and the other side of the worm gear 31 is supported by the support frame 32. The worm gear 31 can rotate normally inside the fixed shell 26. One side of the worm gear 31 is meshed with the worm gear 55. The worm gear 55 is located near the bottom end of the rotating rod 34. By driving the worm gear 55 through the worm gear 31, the worm gear 55 can drive the rotating rod 34 to rotate inside the fixed shell 26. A thread is provided on the rotating rod 34 and a movable block 33 is threadedly connected thereto. Therefore, the movable block 33 will move upward along the rotating rod 34.
