20 or the stamping mechanism is in fault, thereby facilitating the timely troubleshooting and ensuring the product qualification rate, when the detection column 12 moves backwards, the sliding table 24 is driven by the first pull column 11 to slide to one side for a certain distance, so that the inclined end of the inclined plate 15 slides to the lower part of the feed opening 4, at the same time, the electric push rod 42 pushes the next lifting lug 51 to push the previous lifting lug 51 to the guide inclined rod 26 on one side when pushing the next lifting lug 51 for feeding, the lifting lug 51 with failed impact falls from the feed opening 4 to the inclined plate 15 and is guided by the inclined plate 15 to slide to one side of the feed opening 14 for discharging, defective products and qualified products are prevented from mixing together, the products are respectively discharged after detection, after the next lifting lug 51 is fed to the stamping seat 37 and the L-shaped sliding plate 2 returns, the blocking column 39 pushes the second pull column 23 to move backwards, so that the sliding table 24 returns backwards again, the inclined plate 15 and the feed opening 4 are dislocated again, so as to facilitate the next discharging of the qualified products, and after the discharging of the lifting lug 51 in the material placing pipeline 6 is finished, the rotary
