[0002] Aluminum square tube is one of the ceiling materials produced in recent years. Aluminum square tube has an open field of view, ventilation and air permeability. Its lines are bright and neat, and the layers are distinct, reflecting a simple and clear modern style. It is simple and convenient to install and disassemble. It has become a major product that has been popular in the decoration market in recent years. When processing aluminum square tubes, clamps are usually used for clamping to improve processing accuracy.

[0003] When using the existing multi-directional clamp for processing aluminum square tubes, the two ends of the aluminum square tube are usually clamped with claws, while no support structure is set on the other side of the clamping surface, that is, the inner surface of the aluminum square tube. When the clamping force is too large, it is easy to cause deformation of the clamping end.

[0004] Therefore, in order to address the problem that the above-mentioned existing multi-directional clamp for processing aluminum square tubes does not have a supporting function for the interior of the aluminum square tube when in use, which easily causes deformation of the clamping end, a multi-directional clamp for processing aluminum square tubes can be designed. By setting a sleeve, when clamping the aluminum square tube, the two sleeves are respectively inserted into the two ends of the aluminum square tube, and then the electric push rod is started. The electric push rod drives the hollow tube to push the connecting rod to move, and the connecting rod drives the rotating rod to rotate around the hinge point connected to the fixed rod, thereby driving the two support plates to open outward, thereby providing internal support for the clamping surface of the aluminum square tube.
