[0041] When the cross beam pipe 300a is clamped, first manually align at least two cross beam through holes 500 of the cross beam pipe 300a with the support insertion shafts 32 on the same side and make the support insertion shafts 32 inserted into the cross beam through holes 500 of the cross beam pipe 300a, so that the cross beam pipe 300a is hung on the support insertion shafts 32, then control the two cross beam clamping modules 3 to move towards each other, so that the cross beam pipes 300a on the two cross beam clamping modules 3 are respectively pressed on the front and rear ends of the longitudinal beam pipe 400, so that the cross beam pipes 300a are limited to move, at this time, the support insertion shafts 32 push the support mounting seat 37 in reverse and compress the push shaft spring 39, until the cross beam bidirectional screw rod 41 no longer rotates, the sliding rod 38 slides into the wave crest of the wavy annular groove 3731, and the two cross beam pipes 300a are clamped. When the cross beam pipe 300a is welded and fixed, the two cross beam clamping modules 3 move away from each other, so that the support insertion shafts 32 exit the cross beam through holes 500 of the cross beam pipe 300a, at this time, the push shaft spring 39 resets and expands, so that the sliding rod 38 slides from the wave crest to another wave trough, so as to rotate the support insertion shafts 32 to change direction, so that the support insertion shafts 32 can support the next cross beam pipe 300a on the other side, avoiding the problem of downward bending deformation of the support insertion shafts 32 caused by long-term unilateral stress.

[0042] As a preferred embodiment, the insertion shaft buffer rubber pad 30 is sleeved on the support insertion shaft 32 on the front side or on the support insertion shaft 32 on the rear side, in this structure, the support insertion shaft 32 on one side contacts and positions the cross beam pipe 300a by using the insertion shaft limiting part 321, and the support insertion shaft 32 on the other side contacts and positions the cross beam pipe 300a by using the insertion shaft buffer rubber pad 30, which can avoid excessive extrusion of the cross beam pipe 300a and reduce the probability of deformation of the cross beam pipe 300a.
