[0027] In this embodiment, all components are general standard parts or components known to those skilled in the art. Their structures and connection principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. First, a suitable clamping plate is selected according to the size and thickness of the small metal sheet to be processed, and it is installed on the guide rail 4. At the same time, the fastening nut on the third screw is adjusted to ensure that the leveling plate is at an appropriate height. The small metal sheet to be leveled is placed in the placement groove at the upper end of the leveling plate 15. At this time, the transmission baffle 17 is located at the center of the lower end of the leveling plate 15, which helps to keep the plate stable. The operator drives the drive roller by rotating the first throttle 2 on the outside of the device housing 1, thereby driving the entire transmission belt 11 and the transmission column 12 on it to move. With the movement of the transmission belt 11, the leveling plate 15 (along with the small metal sheet on it) is smoothly pushed forward to the working area. When the leveling plate 15 reaches the designated position... At this time, by rotating the second handle 6 on the second screw, the positioning baffle is lowered and embedded in the positioning groove 21 on the guide rail 4, thereby accurately positioning the leveling plate 15, ensuring that the plate does not shift during the entire leveling process. Next, the third screw is adjusted using the third handle 7, causing the leveling plate to move downward until it contacts the surface of the metal plate. The third screw is then tightened until the required leveling pressure is reached. During this process, the guide rod 8 and its limiting block help keep the leveling plate vertical and press down stably, while the guide plate 18 and guide groove 20 ensure that the leveling plate 15 slides smoothly along the guide rail 4, avoiding any unnecessary skewing or shaking. Once the leveling process is complete, the third handle 7 is rotated in the opposite direction to raise the leveling plate, and then the second screw is released to raise the positioning baffle, releasing the leveling plate 15. Finally, the first handle 2 is rotated again, and the conveyor belt 11 is used to send out the leveled plate, preparing for the next plate.
