The first sealing gasket 6 is provided between the spindle box 1 and the gearbox 2 to improve the connection stability between the spindle box 1 and the gearbox 2 and reduce the transmission of vibration.

[0034] In addition, the connecting disk 5 and the adapter disk 10 of the spindle box 1 of the present invention are provided with a connecting assembly, so that the entire spindle box 1 and the adapter disk 10 can rotate 360 ​​degrees left and right. Specifically, the connecting assembly of the present invention includes an annular groove 11 opened on the surface of the adapter disk 10, and two T-shaped bolts 12 are slidably installed inside the annular groove 11. The structure of the annular groove 11 matches the T-shaped bolt 12, and the T-shaped bolt 12 can slide in the annular groove 11; the adapter disk 10 is provided with a T-shaped bolt insertion hole 13 and an adapter connection hole 14, and the surface of the connecting disk 5 is provided with a T-shaped bolt connection hole 15, such as Figure 4 shown.
