[0029] During specific use, the lifting device can lift the plug 21 to contact the ground, and through its characteristics, it can be adsorbed on the ground, so as to fix the connecting rod 11 and then fix the scaffolding 10. The pull rod device can cancel the adsorption of the plug 21 to the ground, so as to cancel the limit fixation of the scaffolding 10.

[0030] To sum up, by setting up a supporting structure, a lifting device and a pull rod device, the lifting device can make the plug 21 rise and fall to contact the ground, and can be adsorbed on the ground due to its characteristics, so as to fix the connecting rod 11 and then fix the scaffolding 10. The pull rod device can make the plug 21 cancel the adsorption on the ground, so as to cancel the limiting fixation of the scaffolding 10. Compared with the prior art, it has the characteristics of easy use, simple structure and strong practicality.

[0031] like Figure 3 , Figure 4 and Figure 5As shown, two lifting steel plates 13 are arranged under the scaffolding 10, and the two lifting steel plates 13 are located at the left and right positions of the two connecting rods 11. A connecting plate 12 is fixedly installed between the two lifting steel plates 13, and a second limiting plate 16 is fixedly installed between the two connecting rods 11.

[0032] A driving motor 17 is fixedly mounted on the top wall of the second limiting plate 16 , and a bolt 15 is fixedly mounted on the output end of the driving motor 17 . The bolt 15 passes through the connecting plate 12 , and the bolt 15 is threadedly connected to the connecting plate 12 .

[0033] A second through hole 19 is provided on the top wall surfaces of the front and rear ends of the lifting steel plate 13, and there are four plugs 21, which are respectively fixedly installed in the cavity of the second through hole 19, and an air pressure hole 22 is provided on the top wall surface of the plug 21. A piston 23 is movably installed in the cavity of the air pressure hole 22, and a first pull rod 24 is fixedly installed on the top wall surface of the piston 23. A driving plate 25 is provided above the first pull rod 24, and a groove 26 is provided on the front side wall surface of the driving plate 25, which is clamped with the first pull rod 24. A first limit plate 14 is fixedly installed on the left and right ends of the front and rear side walls of the connecting rod 11, and the plug 21 penetrates the first limit plate 14, and the plug 21 is movably connected to the first limit plate 14.

[0034] An L-shaped plate 20 is fixedly installed on the top wall of both the front and rear sides of the lifting steel plate 13 in an integral manner, and a limiting slide plate 27 is fixedly installed on the bottom wall of the L-shaped plate 20. The bottom wall of the limiting slide plate 27 is in a hollow state, and the driving plate 25 is movably installed in the cavity of the limiting slide plate 27. The driving motor 17 is connected to the power supply and the switch by electrical signals.

[0035] In specific use, the connecting rod 11 can limit the second limit plate 16, and the second limit plate 16 can limit the driving motor 17.

The up and down movement of the connecting plate 12 can drive the lifting steel plate 13 to move up and down, and the up and down movement of the lifting steel plate 13 can drive the plug 21 to move up and down. When the plug 21 moves downward, it can be adsorbed on the ground, and the first limit plate 14 can limit the plug 21.

[0036] When the driving plate 25 moves upward, it can drive the first pull rod 24 to move upward through the pull groove 26. When the first pull rod 24 moves upward, it can drive the piston 23 to move upward and be pulled out from the cavity of the air pressure hole 22, so that air is injected into the cavity of the plug 21 to make the plug 21 lose its adsorption force on the ground. The limiting slide plate 27 can limit the driving plate 25 to prevent the piston 23 from being unable to be inserted into the cavity of the air pressure hole 22 after leaving the cavity of the air pressure hole 22.

[0037] In summary, by setting the connecting plate 12, the lifting steel plate 13, the first limit plate 14, the bolt 15, the second limit plate 16, the driving motor 17, the first through hole 18, the second through hole 19, the L-shaped plate 20, the plug 21, the air pressure hole 22, the piston 23, the first pull rod 24, the driving plate 25, the groove 26 and the limit slide plate 27, the plug 21 can be adsorbed on the ground by rotating the output end of the driving motor 17. When the plug 21 is adsorbed on the ground, the scaffolding 10 can be limited and fixed. The piston 23 is pulled out of the cavity of the air pressure hole 22 by the driving plate 25, and air is injected into the cavity of the plug 21 to make the plug 21 lose its adsorption force on the ground, thereby canceling the limit fixation of the scaffolding 10.

[0039] A limiting rod 36 is fixedly installed in the cavity of the through groove 35, and a lever 28 is provided on the front and rear sides of the through groove 35. A connecting hole 38 is opened on the left wall surface of one end of the two levers 28 close to the through groove 35. The limiting rod 36 and the connecting hole 38 are movably connected. A first through hole 18 is opened on the front side wall surface of the L-shaped plate 20, and the lever 28 passes through the first through hole 18.

[0040] The lever 28 is located in the cavity of the first through hole 18 and has a rotating column 29 fixedly installed on the left and right side walls. The ends of the two rotating columns 29 that are away from each other are fixedly connected to the left and right side walls of the cavity of the first through hole 18 respectively. The ends of the two levers 28 that are away from each other are hollowed out, and the hollowed ends of the levers 28 are rotatably connected to the left and right side walls of the driving plate 25.

[0041] During specific use, when the staff pulls the second pull rod 33 downward through the handle groove 37, the ends of the two levers 28 that are close to each other can be pulled downward through the through groove 35, the limit rod 36 and the connecting hole 38. When the ends of the two levers 28 that are close to each other move downward, the two levers 28 that are away from each other can be moved upward through the rotating column 29. When the ends of the two levers 28 that are away from each other move upward, the driving plate 25 can be driven to move upward, so as to pull the piston 23 out of the cavity of the air pressure hole 22. The fixed block 32 can limit the second pull rod 33, and the force of the reset spring 34 can make the second pull rod 33 automatically reset.

[0042] To sum up, by setting the lever 28, the rotating column 29, the driving plate 25, the fixing block 32, the second pull rod 33, the reset spring 34, the through groove 35, the limit rod 36, the handle groove 37 and the connecting hole 38, the staff can pull the second pull rod 33 to cancel the adsorption of the plug 21 to the ground, thereby canceling the limit fixation of the scaffolding 10, and then the plug 21 can be moved upward by rotating the output end of the driving motor 17 in the opposite direction to prevent affecting the operation of the scaffolding 10.
