A sleeve 23 is sleeved on the surface of the positioning column 22, and the sleeve 23 is located at the end away from the hydraulic cylinder 21. The surfaces of the sleeve 23 and the positioning column 22 are respectively movably installed with a first connecting rod 24 and a second connecting rod 25, and a fixing plate 26 is movably installed at the other end of the first connecting rod 24 and the second connecting rod 25 and away from the other end of the sleeve 23 and the positioning column 22. The first connecting rod 24 and the second connecting rod 25 are movably connected, the positioning column 22 and the second connecting rod 25 are hinged, the sleeve 23 and the first connecting rod 24 are hinged, and the first connecting rod 24 and the second connecting rod 25 form an X shape, which can position the sleeve 23 and prevent the sleeve 23 from being directly separated from the positioning column 22.

[0027] The surface of the fixing plate 26 is arranged in an arc shape, and a groove is provided on the inner side of the fixing plate 26 to match the first connecting rod 24 and the second connecting rod 25 , so as to facilitate the movement of the first connecting rod 24 and the second connecting rod 25 and prevent the occurrence of a jamming phenomenon.

[0028] A connecting block 27 is fixedly connected to the inner side of the sleeve 23. The connecting blocks 27 are arranged in a ring array and form a circular ring shape. The output end of the hydraulic cylinder 21 passes through the positioning column 22 and extends to the inner side of the sleeve 23 to be fixedly connected to the connecting block 27. The connecting block 27 is located at the end away from the positioning column 22, which can facilitate the up and down linear movement of the sleeve 23.

[0029] The surface of the positioning column 22 is fixedly connected to a limiting block 28, and the limiting blocks 28 are arranged in a ring array. The surface of the sleeve 23 is provided with a ring array of limiting grooves 29. The limiting blocks 28 are located inside the limiting grooves 29 and are movably connected thereto.

[0031] The mounting rods 34 are arranged in a circular array, and the mounting rods 34 penetrate the supporting plate 1 and extend to the bottom of the supporting plate 1 . The mounting rods 34 are movably connected to the supporting plate 1 . The mounting rods 34 can limit the connecting plate 33 to prevent it from rotating with the rotation of the screw rod 32 .
