When the angle of the support plate 11 needs to be adjusted, according to the inclination angle of the stair formwork, the first lead screw 42 and the second lead screw 52 are rotated, thereby driving the first slider 44 and the second slider 54 to move, realizing the adjustment of the distance between the first connecting plate 6 and the second connecting plate 7. When the distance or the position between the first connecting plate 6 and the second connecting plate 7 is different, the inclination angles of the top link 9 and the connecting block 10 are different, thereby completing the angle adjustment of the support plate 11.

[0023] As Figure 2 , Figure 4As shown, the locking assembly 8 includes a connecting shaft 81, a locking roller 82, a locking plate 83, and a locking nut 84.

After the angle of the support plate is adjusted, the worker rotates the locking nut 84 to lock the first connecting plate and the second connecting plate.

[0024] Working process:

[0025] Before the actual use of this device, the worker first moves the device to the designated working location through the universal wheels 12. The setting of the universal wheels 12 increases the flexibility and convenience of the device. After moving to the working location, the worker adjusts the angle of the support plate 11 according to the inclination angle of the aluminum alloy formwork of the stairs. The worker holds the first connecting plate 6 and the second connecting plate 7 and rotates them. The rotating upper plate 22 rotates around the middle shaft 23, thereby realizing the position adjustment of the components above the rotating upper plate 22. After the adjustment is completed, the rotation stops. The worker holds the middle shaft locking nut 25 to lock the rotating lower plate 21 and the rotating upper plate 22. Subsequently, the first lead screw 42 and the second lead screw 52 are rotated, thereby driving the first slider 44 and the second slider 54 to move, realizing the adjustment of the distance between the first connecting plate 6 and the second connecting plate 7. When the distance or the position between the first connecting plate 6 and the second connecting plate 7 is different, the inclination angles of the top link 9 and the connecting block 10 are different, thereby completing the adjustment of the angle of the support plate 11. After the angle of the support plate is adjusted, the worker rotates the locking nut 84 to lock the first connecting plate and the second connecting plate, completing the adjustment of the position and angle of the support plate, thereby realizing the adjustment of the support angle of the support plate 11 for the stair formwork and providing stable support for the formwork, ensuring that the support plate 11 fits the inclined surface of the aluminum alloy stair formwork, which can adapt to the support of stair formworks in different projects, is more convenient to use, reduces construction costs, eliminates the need for manual erection of metal pipes, is convenient for installation and disassembly, and improves work efficiency.
