[0034] Embodiment three, on the basis of embodiment one, a sliding horizontal long groove 27 is opened on the top of the stamping lower module 2, one end of the sliding horizontal long groove 27 is connected to the vertical groove 19, the interior of the sliding horizontal long groove 27 is rotatably connected with a large pitch threaded shaft 28, the surface of the large pitch threaded shaft 28 is threadedly connected with a sliding installation and a moving bar 29 inside the sliding horizontal long groove 27, the middle part of the N-shaped limit push separation plate 3 is fixedly connected to one end of the top of the moving bar 29, one end of the large pitch threaded shaft 28 extends to the outside of the other end of the stamping lower module 2 and is fixedly connected to a second gear 30.

The first parallelogram transmission groove 36 and the second parallelogram transmission groove 37 are staggered up and down, and rollers 38 are installed inside the first parallelogram transmission groove 36 and the second parallelogram transmission groove 37. The axes of the two rollers 38 are respectively connected to the lower parts of the long rotating arm 32 and the short rotating arm 33, so that the long rotating arm 32 and the short rotating arm 33 can be adjusted so that the downwardly moved second rack 34 and the third rack 35 will not perform transmission adjustment on the second gear 30.

[0037] Grooves 39 are provided at the corners of the upper part of the side close to the first parallelogram transmission groove 36 and the second parallelogram transmission groove 37 and at the corners of the lower part of the side away from the first parallelogram transmission groove 36 and the second parallelogram transmission groove 37, and compression springs 40 are fixedly installed inside the grooves 39, and one end of the compression springs 40 is fixedly connected to an extrusion block 41 slidably installed inside the grooves 39, and one end of the extrusion block 41 extends to the inside of the first parallelogram transmission groove 36 and the second parallelogram transmission groove 37, and the lower end of the upper extrusion block 41 of the first parallelogram transmission groove 36 and the second parallelogram transmission groove 37 and the upper end of the lower extrusion block 41 are both inclined structures, so that they can be effectively adjusted;

[0042] Then the third rack 35 that moves upward will separate from the second gear 30, and then the second rack 34 that moves upward will contact the second gear 30 to make the second gear 30 reversely adjusted, and finally the n-shaped limit push separation plate 3 will be reset, and finally the second rack 34 will separate from the second gear 30;
