Then, by holding the handle 16, the rotating plate 12 can be driven to rotate around the rotating shaft one 11. At this time, the groove one 13 on the back side of the rotating plate 12 is aligned and engaged with the front side of the corresponding moving plate 8, so that the limiting hole 14 is aligned with the corresponding reserved hole 9. Then, the limiters 15 on both sides of the rotating plate 12 are inserted into the reserved holes 9 corresponding to the limiting holes 14 to fix the position of the rotating plate 12, thereby forming protection for the front side of the main body 1 and effectively preventing the flying debris from causing harm to the workers. When the stamping work is completed, the limiters 15 are pulled out to release the limiting of the rotating plate 12, and the completed part can be taken out by pulling down the rotating plate 12.
[0034] With reference to Figure 3 and Figure 4 , the cleaning mechanism 2 comprises a groove two 201, which is arranged in the interior of the main body 1, and two telescopic rods 202 are fixedly connected in the interior of the groove two 201.
