At the same time, the first movable ring 405 pushes the first spring 406 and the second movable ring 407, the third movable ring 504, the second spring 505 and the fourth movable ring 506 to move vertically upward until the fourth movable ring 506 presses against the locking plate 503. At this time, the first spring 406 and the second spring 505 continue to be stressed and begin to elastically deform until the total length of the spring assembly is compressed to the required length, and the elastic coefficient of the spring group changes accordingly. At this time, the top support plate 205 is pressed on the top, and the top support plate 205 transmits the pressure to the telescopic sleeve 304 and the third movable ring 504. At this time, the spring group elastically deforms again and generates an upward rebound force, pushing the third movable ring 504 and the topmost top support plate 205 to reset.
