The first lower pressure plate drive mechanism drives the first lower pressure plate to slide along the first lower pressure plate guiding mechanism to make the first lower pressure plate approach or move away from the first upper pressure plate. An inner shaft is also pivotally mounted on the frame. An inner shaft drive mechanism capable of driving the inner shaft to rotate is provided between the frame and the inner shaft. A follower plate swing bracket that rotates with the inner shaft is mounted on the inner shaft. The follower plate is mounted on the follower plate swing bracket and rotates around the inner shaft with the follower plate swing bracket so that when the follower plate rotates, it can drive the workpiece clamped between the first upper pressure plate and the first lower pressure plate to bend around the first roller, but it cannot solve the above problems.
