Flat pipe cutting machine for special-shaped insulating sleeve

The utility model relates to the field of pipe cutting machines, and discloses a flat pipe cutting machine for a special-shaped insulating sleeve, which comprises a supporting table, and a fixing mechanism is arranged at the top of the supporting table. According to the clamping device, the first motor operates to drive the first two-way lead screw to rotate so as to drive the clamping frame to move in the square groove, the second motor operates to drive the second two-way lead screw to rotate so as to drive the clamping blocks to get close to each other, and materials of different lengths can be clamped and fixed through movement of the clamping blocks; materials with different diameters can be clamped and fixed through movement of the clamping frame, and through the arrangement of the structure, sleeves with different sizes can be effectively fixed, so that the overall practicability of the device is improved, and the problem that the sleeves with different sizes cannot be fixed in the using process of the
