[0025] The connecting arm 6 has connecting end plates a15 welded to both ends. One end of the main arm 5 is fixedly connected to the outer ring of the rotary pressure bearing 4, and the other end of the main arm 5 is welded to a connecting end plate b16. The connecting end plate b16 on the main arm 5 is bolted to the connecting end plate a15 at one end of the connecting arm 6. The connecting end plate a15 at the other end of the connecting arm 6 is bolted to the connecting component. The connecting component includes a connecting end plate c14, a horizontal plate 12, and a mounting post a13.
