The clamping block 205b is separated from the clamping slot at the top of the feeding plate 203c, and the clamping block 205b squeezes the inclined surface of the transmission block 206b. The transmission block 206b is squeezed and moves into the slot W. The transmission block 206b squeezes the fourth spring 206c, and the fourth spring 206c generates a thrust on the squeezing block 206a. The squeezing block 206a squeezes the material in the material box 201d through the friction pad, and the reaction of the first spring 203i The force drives the round rod 203g to move and reset through the circular plate 203h, and the round rod 203g drives the feeding plate 203c and the tooth plate 203b to move and reset through the connecting rod 203a. The reaction force of the third spring 205f pushes the block 205b to move and reset, and the block 205b drives the third limiting rod 205d and the ball 205e to move and reset, and the motor 202a drives the gear 202b and the pushing column 202c to rotate continuously. After the pushing plate 204c is separated from the conical inclined surface of the pushing column 202c, the pushing plate 204c is pulled by the second spring 204d to move and reset, and the pushing plate 204c pushes the spring piece processed on the top of the module 201c away from the module 201c, and this cycle is repeated.
