The main body part of the floating component 3 can be a thin sheet or other shapes, the periphery of the floating component 3 can be in clearance fit with the inner wall of the ring seat 2, so that the ring seat 2 plays a certain guiding role in the lifting of the floating component 3; the upper surface of floating component 3 can also set up jack-up boss 9, and the lower surface and the jack-up boss 9 of shell fragment 4 closely cooperate, and jack-up boss 9 makes floating component 3 jack-up shell fragment 4 upwards more easily.
