[0036] The working principle of this embodiment: When it is necessary to adjust the main frame 1, first rotate the rotating shaft 14 through an external hexagonal tool to drive the stud 3 to rotate. The stud 3 drives the moving rod 2 to move. After the moving rod 2 moves to a suitable position, adjust the distance between the moving seats 4 according to the on-site situation. After the adjustment is completed, turn the bolt 11 and drive the locking plate 10 to tighten the main frame 1 or the moving rod 2 to complete the fixation of the moving seat 4. Then rotate the rotating rod 6 to drive the screw rod 7 to move. The screw rod 7 drives another group of main frames 1 to move through the moving seat 4. When the distance between the two groups of main frames 1 is appropriate, stop rotating the rotating rod 6 to complete the adjustment of the main frame 1.
