As shown in fig. 1, a plurality of guide posts 105 are disposed at intervals along the length direction of each vertical plate 101 at the top of each vertical plate 101, and correspondingly, a plurality of through holes are disposed at two sides of the upper seat body 2, and the upper seat body 2 is guided to slide on the lower seat body 1 through the through holes in the corresponding guide holes, so that the upper seat body 2 is guided to slide on the lower seat body 1.

In this embodiment, the second adjusting block 104 is disposed on the top of each vertical plate 101, and the first adjusting block 204 is disposed on the bottom of the upper base 2. The first inclined surface 2041 and the second inclined surface 1041 are attached to each other, and the second adjusting block 104 is perpendicular to the moving direction of the upper seat 2 due to the guidance of the first inclined surface 2041 and the second inclined surface 1041. Here, the arrangement of the first inclined plane 2041 and the second inclined plane 1041 is favorable for converting the sliding of the second inclined plane 1041 along the length direction of the lower seat body 1 into the sliding of the upper seat body 2 in the height direction, so as to be favorable for realizing the adjustment of the distance between the upper seat body 2 and the lower seat body 1, and further, the distance between the upper conveying roller 202 and the lower conveying roller 109, and the distance between the upper straightening roller 203 and the lower straightening roller 110 can be adjusted.

In particular, in order to facilitate the arrangement of the first adjusting block 204 and the second adjusting block 104, as shown in fig. 1, 4 and 5, lower connecting protrusions 108 extending outward from both ends are respectively provided at both ends of each vertical plate 101.
