[0030] In summary, when in use, the iron core body 12 is placed on the bottom plate 1, and the rotating part one 8 is rotated to drive the gear 6 connected thereto to rotate. The belt 7 is the transmission center of the two gears 6, so that the two gears 6 and the two one-way lead screws 4 rotate synchronously. The two one-way lead screws 4 drive the sliding plate 5 to move downward, so that the sliding plate 5 is pressed on the top of the iron core body 12.
