[0027] The number of nuts 9 is two groups. The two groups of nuts 9 are threadedly connected to the outer wall of the screw 7. The screw 7 passes through the first through hole 5 in the end face limiting plate 1, and the screw 7 passes through the second through hole 6 in the limiting clamping plate 2; the gasket 10 is movably sleeved on the outer wall of the screw 7; the annular cover 12 is fixedly installed on the outer surface of the side of the limiting disc 11 away from the screw 7. The number of extrusion rods 13 and third through holes 14 is four groups each. The four groups of third through holes 14 are opened on the outer surface of one side of the limiting disc 11, and the extrusion rod 13 passes through the third through hole 14. The limiting annular plate 15 and the compression spring 16 are both located inside the annular cover 12; the upper outer surface of the four groups of extrusion rods 13 is fixedly connected to the lower outer surface of the limiting annular plate 15, and the compression spring 16 is fixedly installed between the upper outer surface of the limiting annular plate 15 and the upper part of the inner cavity of the annular cover 12; the outer wall of the extrusion rod 13 is slidably connected with the third through hole 14, and the upper outer surface of the limiting annular plate 15 is elastically connected to the upper part of the inner cavity of the annular cover 12 through the compression spring 16.
