When the bidirectional screw rod 1021 rotates, it drives the nut 1022 to move left and right. When the nut 1022 moves, it drives the clamp 202 to move left and right through the connecting rod 201 until the two groups of clamps 202 are adjusted to the appropriate position, and then the servo motor 1032 is turned off, so that the clamp 202 is suitable for the placement of aluminum plate bodies 203 of different lengths, thereby improving the universality of the device.
