[0030] When using this device, hold the push rod 4 to move the cart plate 1. This will cause the roller 52 to rotate.

The column rods 723 are movably installed in the first mounting frame 72 and the second mounting frame 74, respectively. Therefore, as the first adjusting rod 712 and the second adjusting rod 732 rotate in opposite directions, they can drive the first mounting frame 72 and the second mounting frame 74. When the first mounting frame 72 and the second mounting frame 74 move up and down, they can drive the telescopic plate 79 and the active ramming plate 6 to move up and down. When the first mounting frame 72 moves up and down, it can also drive the first active rack 76 to move up and down, thereby driving the first spur gear 761 to rotate in opposite directions, which in turn drives the second active rack 762 and the first...
