when the first joint and the second joint are clamped in place, the connecting pipe is sleeved in the first hole and the second hole in a sealing mode.
8. The quick connect coupling for a pipe/column element of claim 7, wherein said first bore inner wall has a first step surface facing the open end of the recess; the inner hole wall of the second hole is provided with a second step surface facing the end surface of the bulge; when the first connector and the second connector are clamped in place, two ends of the connecting pipe are respectively abutted to the first step surface and the second step surface.
9. The quick-connect structure for pipe/column members as claimed in any one of claims 1 to 8, further comprising a sliding key; the sliding key is in sliding connection with the first joint along the axial direction and is provided with an inserting part and an operating part exposed out of the outer wall of the first joint; the insertion part axially extends into the groove perpendicular to the first connector and is inserted into the clamping sleeve, and the clamping sleeve is driven by the insertion part to slide between the first position and the second position, so that the convex rib is inserted into or separated from the first interval or the second interval.
10. A quick-connect structure for pipe/column structural members as claimed in claim 1, wherein said elastic member is a spring; one surface of the cutting sleeve, which is abutted against the spring, is provided with an annular positioning groove; the positioning groove is used for placing the end part of the spring.
