[0026] By extending the connecting holes into different limiting grooves 7 , the distances between the abutment plate 33 and the clamping plate 32 are made different, so that materials of different sizes can be placed on the workbench 2 , thereby improving the practicality of the punching machine body 1 .

[0027] Working principle: first place the material on the workbench 2, and place the material between the two limit blocks 31, then drive the motor 36 to rotate the shaft 5, and then the shaft 5 drives the screw rod 35 to rotate, because the screw rod 35 is threadedly connected with the threaded hole 6 on the slider 34, and then the screw rod 35 rotates and drives the slider 34 to move in the connecting groove 4, and then the connecting groove 4 drives the clamping plate 32 to move toward the material until the clamping plate 32 contacts the material and drives the material to move, and then the connecting block 8 on the contact plate 33 is extended into the corresponding limit groove 7, and the clamping plate 32 drives the material to move until the other end of the material contacts the contact plate 33, and then the material is fixed on the workbench. 2 and perform stamping work on it, and then move the stamped materials to the collection box 91 through the guide plate 92 for collection. When the collection box 91 is full, the knob 101 is rotated, and the knob 101 drives the fixed block 102 to move, and then the fixed block 102 drives the clamping block 103 to rotate, and then the clamping block 103 moves from the arc groove 14 to the clamping groove 13, and then the knob 101 is pulled to move the clamping block 103 and the fixed block 102 out of the clamping groove 13 and the limiting hole 12 respectively, and then the collection box 91 is moved out of the punching machine body 1, and the materials in the collection box 91 are poured out and reinstalled on the punching machine body 1.
