[0008] The quick-install clamp includes two hinged clamps. The inside of the two clamps has clamping holes that match the contour of the outer wall of the outrigger. After the lower arm and outrigger are inserted, the clamping holes of the clamps are fitted to the grooves on the upper end of the outrigger. The two clamps are connected by the first threaded assembly. The clamping holes tightly press against the outer wall of the outrigger, so that the lower arm and outrigger can be quickly and securely installed to form a portal frame.

[0009] The quick-release clamp includes a ∩-shaped card and a support block. The support block is fixedly connected to the bottom of the upper beam. The upper surface of the support block is provided with a limiting groove. The support block is installed at the lower end of the ∩-shaped groove of the card and is fixedly connected by a second threaded assembly.

[0017] In some embodiments, the ∩-shaped groove and the limiting groove surround to form a rectangular cavity or a circular cavity;

[0018] The longitudinal connecting rods are corresponding rectangular or round tubes. Several support blocks are welded in the middle of the upper or lower surface of the top beam. Multiple parallel longitudinal connecting rods are fixedly connected to the cavity of the quick-assembly clamp of multiple parallel connecting devices, thus forming a steel structure.

[0019] In some embodiments, the upper end of the ∩-shaped groove and the limiting groove surround to form a circular cavity; the longitudinal connecting rod is slidably connected in multiple parallel cavities, the roller at the upper end of the spreader is rolled on the longitudinal connecting rod, and the hook at the lower end of the spreader can hold the carrier loaded with goods, thereby forming a steel structure with a conveying channel.
