Two cross folding frames 14 are provided above the bottom plate 1, and two groups of connecting blocks 13 are fixedly connected on the side facing each other of the bottom plate 1 and the support plate 3. The number of each group of connecting blocks 13 is set to two, and the two ends of the two cross folding frames 14 are rotatably connected to the corresponding group of movable blocks 12 and connecting blocks 13 respectively.

[0024] Reference Figure 1-Figure 3 The interior of one of the vertical plates 2 is rotatably connected to a rotating rod 5, one end of the rotating rod 5 extends through and extends to the outside of the vertical plate 2 and is fixedly connected to a rotating handle 4.

[0025] When the supporting device needs to be folded for transportation, first rotate the handle 4, the handle 4 drives the rotating rod 5 to rotate, the rotating rod 5 drives the worm 6 to rotate, the worm 6 drives the worm gear 7 to rotate, the worm gear 7 drives the reciprocating screw 8 to rotate, the reciprocating screw 8 drives the slider 9 to move, and when the slider 9 moves, it drives the connecting rod 10 to move, and the movement of the connecting rod 10 drives the movable block 12 to slide to the left on the long rod 11, so that the angle between the cross folding frames 14 becomes larger, and then the support plate 3 moves downward, and the supporting device is folded for easy transportation.

[0026] Reference Figure 4-Figure 6 Two through slots are provided inside the support plate 3, wherein the two movable blocks 12 are respectively slidably connected to the corresponding through slots, wherein an ejection assembly is provided above the two movable blocks 12, and the ejection assembly includes two groups, each group of ejection assemblies includes a sliding block 16, the sliding block 16 is fixedly connected to the top of the movable block 12, and one side of the sliding block 16 is rotatably connected to a connecting rod 17, a trapezoidal slot 15 is provided inside the support plate 3, one end of the connecting rod 17 is slidably connected to the trapezoidal slot 15, and the other end of the connecting rod 17 is provided with a fixing rod 18, the fixing rod 18 is located inside the through slot, and a fixing assembly is provided on the top of the fixing rod 18.

[0027] Through the setting of the ejection assembly, when the supporting device is transported to the construction site and needs to temporarily support the steel structure 29, the upper movable block 12 first moves to the right. While moving to the right, the upper movable block 12 drives the sliding block 16 to move inside the through groove. When the movable block 12 is about to move to the bottom of the steel structure 29, the sliding block 16 drives the connecting rod 17 to move into the trapezoidal groove 15. The inner wall of the trapezoidal groove 15 slowly squeezes one end of the connecting rod 17, causing the other end of the connecting rod 17 to tilt, and then the fixing rod 18 pushes the connecting shell 19 out of the through groove, causing the connecting shell 19 to slowly rise into the prefabricated groove.

[0028] Reference Figure 6-Figure 8 The fixing assembly includes two groups, each of which includes a connecting shell 19, which is fixedly connected to the top of the fixing rod 18. A telescopic rod 22 is provided inside the connecting shell 19, and the outer wall of the telescopic rod 22 is provided with a return spring 23. The top of the telescopic rod 22 is fixedly connected to an extrusion rod 20, and the outer wall of the extrusion rod 20 is slidably connected to a moving block 21.

The opposite ends of the two sliding rods 26 extend through the outside of the connecting shell 19 and are fixedly connected to a card block 28.

[0029] By setting the fixing assembly, the steel structure 29 can be fixed.

When the extrusion rod 20 contacts the inner top of the prefabricated groove, the moving block 21 moves downward to squeeze the telescopic rod 22 and the return spring 23. While moving downward and squeezing, it drives the push rods 24 on both sides to push the trapezoidal blocks 25 to both sides, so that the sliding rods 26 on both sides move outward, so that the blocking block 28 is pressed against the inner wall of the prefabricated groove, so that the steel structure 29 can be more stable when the supporting device is temporarily supported.

[0030] Reference Figure 6-Figure 8 The two ends of the return spring 23 are fixedly connected to the shift block 21 and the connecting shell 19 respectively, the two ends of the extrusion spring 27 are fixedly connected to the trapezoidal block 25 and the connecting shell 19 respectively, the two slide rods 26 are both slidably connected to the connecting shell 19, a steel structure 29 is provided above the support plate 3, a prefabricated groove is opened inside the steel structure 29, the connecting shell 19 is located inside the prefabricated groove, and the two blocking blocks 28 are in contact with the two ends of the prefabricated groove respectively.

When the slider 9 moves, it drives the connecting rod 10 to move, and the connecting rod 10 moves to drive the movable block 12 to slide left on the long rod 11, so that the angle between the cross folding frames 14 becomes larger, thereby causing the support plate 3 to move downward, and the support device is folded for convenient transportation; when the steel structure 29 needs to be temporarily supported, the handle 4 is turned in the opposite direction to make the movable block 12 move to the right on the long rod 11, and while moving to the right, it drives the sliding block 16 to move inside the through groove. When the movable block 12 is about to move to fit the bottom of the steel structure 29, the sliding block 16 drives the connecting rod 17 to move into the trapezoidal groove 15, and the inner wall of the trapezoidal groove 15 slowly squeezes one side of the connecting rod 17 When the support plate 3 is not needed to support the steel structure, the support plate 3 moves downward through the folding assembly, and the two blocks 28 can move inward and then move out of the prefabricated groove.
