When the position of the second rotating shaft 8 is adjusted, pressure is applied to the rotating shell 7 by the pressing unit to fix the rotating shell 7 relative to the sealing plate 6, thereby completing the adjustment of the position of the second rotating shaft 8 and ensuring that the second rotating shaft 8 is coaxially arranged with the shaft to be driven. The staff coaxially and fixedly connects the second rotating shaft 8 with the shaft to be driven. The output end of the hydraulic motor body 1 drives the first rotating shaft 4 to rotate through the clamping piece, and the first rotating shaft 4 drives the second rotating shaft 8 to rotate through the meshing transmission structure. The second rotating shaft 8 can drive the shaft to be driven to rotate.

When the rotating shell 7 and the supporting ring 17 rotate relative to the sealing plate 6, the rotating shell 7 drives the fourth bevel gear 16 to roll on the third bevel gear 15 through the second rotating shaft 8. When there is no need to drive the rotating shell 7 to rotate relative to the sealing plate 6, the pressing plate 19 is driven to move upward through the first hydraulic telescopic rod 18 so that the top of the pressing plate 19 presses the bottom of the support ring 17, and the support ring 17 and the rotating shell 7 are fixed relative to the sealing plate 6. When the first rotating shaft 4 rotates, the first rotating shaft 4 drives the first bevel gear 10 to rotate, and the first bevel gear 10 drives the transmission shaft 9 to rotate through the second bevel gear 11, and the transmission shaft 9 drives the rotating sleeve 12 and the third bevel gear 15 through the guide strip 13.

[0040] The third rotating shaft 48 is consistent with the axis of the first rotating shaft 4, and the swing shell 5 is supported by the third rotating shaft 48, so that the swing shell 5 can swing smoothly relative to the mounting bracket 3. When the mounting bracket 3 needs to be disassembled from the base 2, the staff drives the fixing plate 36 and the positioning column 35 to move upward, so that the bottom end of the positioning column 35 is disengaged from the corresponding second positioning groove 38, and the tension spring 37 is in a stretched state, releasing the limitation on the position of the mounting bracket 3, and the staff drives the mounting bracket 3 to move in the direction away from the hydraulic motor body 1, so that the positioning plate 33 is disengaged from the first positioning groove 32, and the block 30 is disengaged from the groove 29, and the removal of the mounting bracket 3 is completed. Similarly, the above steps can be reversed to fix the mounting bracket 3 relative to the base 2, so that the block 30 is located in the groove 29. When the main body 1 drives the card block 30 to rotate, the card block 30 drives the first rotating shaft 4 to rotate synchronously through the fixed block 47. The staff opens a slot compatible with the plug block 43 on the shaft to be driven. Before the second rotating shaft 8 is coaxially set with the shaft to be driven, the staff drives the plug block 43 to move through the handle 46 so that the plug block 43 slides completely into the slide groove 42, and the compression spring 44 is in a compressed state. When the second rotating shaft 8 is coaxially set with the shaft to be driven, the plug block 43 moves to one side of the slot on the shaft to be driven.
