Finger training machine

The invention belongs to the technical field of finger rehabilitation, and particularly relates to a finger training machine. The machine comprises a mounting shell, a rotating shaft, a supporting plate, a transmission mechanism, a circular through hole, a square through hole and a driving mechanism. When people need to swing the whole finger up and down, a driving shell mounted at one end of a driving wheel is controlled to swing; and the swing of the driving shell mounted at one end of the driving wheel drives the whole mounting shell to swing so as to drive a driving shell mounted at one end of a transmission wheel to swing, and to swing the hands needing to be trained. When people need to rotate fingers, the driving shell mounted at one end of the driving wheel is controlled to rotate;the driving shell can drive the driving wheel to rotate; the driving wheel drives a middle wheel to rotate through a belt; the middle wheel drives the transmission wheel to rotate; and the transmission wheel rotates to drive
