When cutting square tubes with thinner outer walls, since the inside of the square tube is hollow and the outer wall of the square tube is thin, it is subjected to the pressure of the cutter head. During the cutting operation, the cutting head position is easily deformed, which affects its normal use after cutting, resulting in the cutting processing of the square tube being not conducive to ensuring the quality of the cutting head.

When in use, the vertical plate 22 can be supported by the left fixing frame 2 fixedly connected to the bottom plate 1, so that the vertical plate 22 can be supported and fixed on one side of the cutting assembly 11. The plurality of front clamps 23 installed on the vertical plate 22 can clamp and fix the rectangular tube. When the square tube is clamped by the front clamp 23 so that it is located at the center of the vertical plate 22, the rectangular tube can be inserted and sleeved on one side of the mounting rod 331 and the support rod extension rod 33.

Under the support of the support plate 36, the deformation of the cutting position caused by the downward pressure exerted by the cutting head on the square tube can be reduced, so that the device can increase the quality of the incision after the square tube is cut. At the same time, the support rod extension rod 33 passes through the adjustment component 25. The adjustment component 25 is used to clamp one end of the square tube. By continuously pushing the adjustment component 25 to move, the square tube can be continuously moved outward from the vertical plate 22, so that the square tube can be continuously cut. At the same time, it is always supported and limited by the installation rod 331 and the support plate 36 to ensure the quality of the cut head after cutting.

[0022] The working principle and use process of the utility model are as follows: by sleeve-arranging the square tube on one side of the mounting rod 331 and the support rod extension rod 33, the mounting rod 331 is supported by the support rod extension rod 33 and is located at the center of the vertical plate 22, and the outer part of the square tube can be clamped by a plurality of front clamps 23 installed on the vertical plate 22, and then the threaded rod 31 is rotated to adjust the position of the threaded rod 31 on the fixed rod 3, so that the mounting rod 331 at one end of the support rod extension rod 33 can be adjusted synchronously therewith, and before the square tube is sleeved on the outer side of the mounting rod 331, the plurality of support plates 36 are adjusted to a position that fits the inner wall of the square tube, so that the bottom plate 1 can be used to adjust the mounting rod 331 on the fixed rod 3. When the square tube is cut, the support of the mounting rod 331 and the support plate 36 can reduce the deformation of the cutting position caused by the downward pressure exerted by the cutting blade on the square tube, thereby enabling the device to increase the quality of the incision after the square tube is cut. At the same time, the support rod extension rod 33 passes through the adjustment component 25, and the adjustment component 25 is used to clamp one end of the square tube. By continuously pushing the adjustment component 25 to move, the square tube can be continuously moved outward from the vertical plate 22, so that the square tube can be cut continuously. At the same time, it is always supported and limited by the mounting rod 331 and the support plate 36 to ensure the quality of the cut head after cutting.
