In this embodiment, a shaft sleeve 101 is disposed at one end and the outer side of the rotary main shaft 1, threaded oil channels 102 are disposed at two ends and the inner side wall of the shaft sleeve 101, oil grooves 17 are symmetrically disposed at one end and the outer side wall of the shaft sleeve, the main shaft 1 is connected with one end of the front supporting seat 6, and the other end of the front supporting seat 6 is connected with the front supporting plate 7. The shaft sleeve is newly added to achieve the structure of the shaft center shaft, and the friction is reduced by using lubricating oil. Further, the top of the front supporting seat 6 is provided with an oil port 8, the oil port 8 is arranged at the top and the middle position of the front supporting seat 6 and penetrates through a threaded oil duct 102 outside the shaft sleeve 101, the other end of the rotating main shaft 1 is hinged with one end of the rear rotary table 9, the other end of the rear rotary table 9 is fixedly connected with the first driving motor 3, and the rear rotary table 9 is fixedly arranged in the middle of the rear supporting seat 4. The newly added oil port is simple in structure and easy to operate, and when lubricating oil flows into the threaded pipeline, friction of a shaft center shaft is reduced, and an expensive gear assembly in the main shaft box is better protected.
