[0031] Working principle: when using the device and performing punching and shearing, the punching and shearing materials are placed inside the first punching and shearing groove 2 and the second punching and shearing groove 5, and the hydraulic device at the upper end of the shell 1 is started. The push of the hydraulic device causes the movable plate 4 to drive the cutting knife 6 to move longitudinally downward to complete the punching and shearing. The contraction of the hydraulic device completes the resetting of the movable plate 4. The movable plate 4 drives the cutting knife 6 to move longitudinally downward while driving the fixing bar 7 to move longitudinally downward. The longitudinal downward movement of the fixing bar 7 will drive the second side tooth groove 10 to rotate by the first side tooth groove 8 on one side. The rotation of the second side tooth groove 10 will drive the third side tooth groove 11 to rotate through the transmission block 13. The rotation of the third side tooth groove 11 will drive the transmission ring 15 to rotate clockwise through the fourth side tooth groove 16. The transmission ring 15 will drive the ratchet groove 17 to rotate. The ratchet groove 17 continuously fits the limiting block 18, so that the limiting block 18 continuously shrinks into the inside of the wire rack 19, and the spring 20 inside the wire rack 19 continuously pushes and makes the limiting block 18 fit the ratchet groove 17. When the movable plate 4 moves longitudinally upward and resets, the fixed bar 7 rotates counterclockwise through the transmission of the first side tooth groove 8, the second side tooth groove 10, the transmission block 13, the third side tooth groove 11 and the fourth side tooth groove 16. The counterclockwise rotation of the fourth side tooth groove 16 drives the first connecting shaft 21 to rotate counterclockwise through the limiting block 18. The first connecting shaft 21 drives the second gear 23 to rotate clockwise through the first gear 22. The second gear 23 drives the roller 3 to rotate clockwise through the second connecting shaft 24. The clockwise rotation can push out the punching and shearing material in the shell 1.
