[0043] An annular groove 30 is provided at the top of the first annular plate 11, and the second annular plate 31 is fixedly mounted on the bottom of the circular plate 20, and the bottom end of the second annular plate 31 is inserted into the annular groove 30, and positioning holes 32 are provided on both sides of the bottom end of the second annular plate 31, and limiting holes 33 are provided on both sides of the top of the second annular plate 31. U-shaped plates 34 are fixedly installed on both sides of the first annular plate 11, and a positioning rod 35 is slidably connected to the U-shaped plate 34, and one end of the positioning rod 35 passes through the first annular plate 11 and is inserted into the positioning hole 32, and one end of the positioning rod 35 is set to an inclined surface, and a limiting plate 36 is fixedly mounted on the other end of the positioning rod 35, and a spring 37 is sleeved on the positioning rod 35, and the two ends of the spring 37 are fixedly connected to the limiting plate 36 and the U-shaped plate 34 respectively. When the two groups of limiting plates 36 move backwards, the spring 37 will be Stretching, on the contrary, when the two groups of limiting plates 36 move toward each other, their springs 37 will be compressed (that is, restored to a normal state), and the third annular plate 38 is slidably connected to the second annular plate 31, and the first connecting rods 39 are fixedly installed at both ends of the inner cavity of the third annular plate 38, and the first connecting rods 39 are slidably connected in the limiting hole 33, and one end of the first connecting rod 39 is integrated with a second connecting rod 391, and one end of the second connecting rod 391 is integrated with a third connecting rod 392, and the third connecting rod 392 is slidably connected to the bottom end of the positioning hole 32, wherein the first connecting rod 39, the second connecting rod 391 and the third connecting rod 392 are arranged in a U shape, and one end of the third connecting rod 392 is in contact with one end of the positioning rod 35, and in addition, one end of the third connecting rod 392 is flush with the outer surface of the second annular plate 31.
