The first sealing plate 112 flips back under the push of the first push plate 113. At this time, since the first connecting block 103 is against the bottom of the processing cover 102 and cannot move, the oil cylinder 107 acts on the second push plate 114 to make the second push plate 114 move relative to the first push plate 113. The second push plate 114 pushes the fourth push rod 122 to move upward to push the second protrusion 1202 out of the second through cavity. The second protrusion 1202 uses the first movable rod 120 to drive the first protrusion 1201 to move together, so that the first protrusion 1201 moves out of the fixed groove. 124, the first protrusion 1201 moves and drives the first transmission wheel 135 to move, the sixth push rod 134 pushes the third push rod 133 to move, the third push rod 133 pushes the limit block 131 out of the limit groove 132, the fourth connecting spring 1301 pulls the second movable rod 130 into the third movable groove, the first connecting spring 118 pulls the second connecting block 117 into the first movable groove, the oil cylinder 107 drives the first push plate 113 and the second push plate 114 to descend, the first connecting block 103 descends and disengages from the processing cover 102, the first hydraulic cylinder 105 and the second hydraulic cylinder drive the mounting block 109 and the processing cover 102 to rise, so as to collect the processed plates.;
