Improved transmission mechanism of circular knitting machine

According to the improved transmission mechanism of the circular knitting machine, the lower end of a vertical wheel shaft is fixedly sleeved with a gear through a key strip, a bearing seat with a two-way bearing is sleeved upwards from the bottom end of the vertical wheel shaft, and the bearing seat with the two-way bearing is sleeved under the gear; the bottom end of the vertical wheel shaft isfixedly sleeved with a synchronous wheel through a key strip, and the synchronous wheel is fixedly sleeved under a bearing seat with a two-way bearing; an upwards-sunken embedding groove is milled inthe middle of the bottom face of the synchronous wheel, and the one-way bearing is upwards placed in the embedding groove and connected with the bottom end of the vertical wheel shaft in a sleeved mode. The locking screw is connected with a circular-ring-shaped top piece in series and then screwed in upwards from the middle of the bottom face of the vertical wheel shaft, and the circular-ring-shaped top piece can fasten th
