The supporting column 105 currently provided can change its own position under the adjustment of the adjusting screw 107, thereby changing the bending angle of the square tube during the bending process. This design is easy to operate and solves the problem that the square tube can only be bent according to a predetermined bending route during the bending process, and the bending angle of the square tube cannot be adjusted, thereby limiting the scope of application.

By rotating the adjusting handle 108, the adjusting screw 107 and the supporting column 105 are driven to change their positions, thereby changing the bending angle of the square tube during the bending process. To achieve a bending angle, the staff first places the square tube between the top frame 112 and the positioning angle iron 111, and then rotates the rotating rod 114 to hold the clamping screw 113 against the square tube, clamping and fixing the other tube for subsequent bending.

Due to the action of the holding column 105, the square tube is pressed and bent, thereby completing the bending of the other tube.
