Since the sizes of square tubes of different specifications are different when squaring the square tubes, it is necessary to adjust the gap between the squaring components according to the actual square tubes to be squaring. The squaring mechanism does not have an adjustment mechanism, which makes it inconvenient to square square tubes of different specifications, reducing the scope of use of the squaring mechanism.

[0005] Secondly, the existing square tube squaring machine does not have an adjustable guiding mechanism. Since the square tube is easily deviated when squaring the other tube, the squaring effect of the square tube is poor and inaccurate.
