[0033] This device can be used for clamping metal plates of different lengths and thicknesses and metal pipes of different lengths and diameters. A set of clamps has two uses and can directly switch between clamping plates or pipes, reducing the cost of using the clamps and the time cost of replacing them.

[0034] One end of the bidirectional lead screw 3 passes through the first sliding adjustment slot 2 and is connected to the output shaft of the reduction motor 4 . The reduction motor 4 is fixedly mounted on the side of the base 1 .

[0035] The reduction motor 4 drives the bidirectional screw rod 3 to rotate and drive the first slider 7 of the left dual-purpose clamping mechanism 5 and the first slider 7 of the right dual-purpose clamping mechanism 6 to move toward or away from each other, thereby adjusting the distance between the left dual-purpose clamping mechanism 5 and the right dual-purpose clamping mechanism 6.

[0036] The second sliding adjustment slot 14 is inclined at 45 degrees.

[0037] The second sliding adjustment groove 14 is inclined at 45 degrees, so that when the dual-purpose clamping plates 16 are slidably adjusted along the second sliding adjustment groove 14, each group of dual-purpose clamping plates 16 are located on the same circle, meeting the clamping requirements for the pipe.
