[0103] In the technical solution, when the seat body 71 is in a horizontal use state, the clamping rod is clamped in the first notch and the second notch, and the fixing plate 74 can prevent the seat body 71 from rotating downward; because the clamping plate 77 is tilted downward, when the seat body 71 rotates upward, the clamping rod drives the clamping plate 77 to move upward, and the existence of the spring 76 prevents the clamping plate 77 from continuing to move upward, thereby preventing the seat body 71 from rotating upward, thereby locking and fixing the seat body 71 to be in a horizontal state. When the seat body 71 needs to be rotated upward, the handle 75 is pulled outward, and the handle 75 drives the clamping plate 77 to rotate upward through the spring 76, so that the opening of the second notch rotates upward, and the clamping rod can be separated from the second notch, so that the seat body 71 can rotate upward, and the seat body 71 can be folded on the working structure 4. When the seat body 71 rotates downward, the clamping rod is clamped on the second notch, driving the clamping plate 77 to rotate downward to a downward tilted state, and the clamping rod is clamped in the first notch and the second notch at the same time to realize the locking of the seat body 71.

[0104] In another technical solution, a limiting protrusion is provided below the fixing plate 74 to limit the rotation angle of the handle 75. By providing the limiting protrusion, the rotation angle of the handle 75 can be limited.

[0112] The auxiliary stabilizing structure comprises:

[0113] A first auxiliary rod, comprising a first rod body 97 and a second rod body 96, wherein the first rod body 97 and the second rod body 96 are rotatably connected so that the first rod body 97 can be folded to a state parallel to the second rod body 96, the lower end of the first rod body 97 is detachably connected to the bottom of the bottom frame structure, and the top of the second rod body 96 is detachably connected to the seat support rod;

[0114] At least one second auxiliary rod 98 is disposed between the second rod body 96 and the second height-increasing rod 92 .

[0115] In this technical solution, by providing a height-increasing structure, the height of the working structure 4 can be increased. By adding an auxiliary stabilizing structure, the stability of the working structure 4 can be increased, and the construction personnel can climb up the working structure 4 through the second auxiliary rod 98 .

[0116] In another technical solution, the working structure 4 is a rectangular structure, and a ladder structure 8 and a ladder groove are provided on the upper surface of the working structure 4. The ladder structure can be stored in the ladder groove, and the ladder groove includes:

[0117] The receiving groove 84 has a rectangular cross section;

[0118] A limiting groove, which is a dovetail groove 85, and the limiting groove is arranged below the receiving groove 84;

[0119] The ladder structure 8 includes three ladder body units connected in sequence by connecting members, a first dovetail block 87 is hinged at the free end of the left ladder body unit, and the first dovetail block 87 is slidably matched with the dovetail groove 85, and a second dovetail block 88 is fixedly arranged on the free end of the right ladder body unit, and the second dovetail block 88 is vertically arranged with the ladder body unit, each connecting member includes two connecting shafts, a bottom plate and two groove wall plates, and the groove wall plates are vertically arranged on both sides of the bottom plate to form a U-shaped groove structure, and the ladder body unit is hinged with the groove wall plates through the connecting shaft so that the ladder body unit can rotate relative to the connecting member; when it is necessary to climb up the working structure 4, the first dovetail block 87 is overlapped in the dovetail groove 85, and the second dovetail block 88 is abutted on the ground, and the construction personnel can climb up the working structure 4 through the three ladder body units connected in sequence, namely the first ladder body unit 81, the second ladder body unit 82, and the third ladder body unit 83;

[0120] When it is necessary to increase the height of the working structure 4, the first dovetail block 87 slides to the left side of the dovetail groove, the first ladder body unit 81, the second ladder body unit 82, and the third ladder body unit 83 are folded to form a U-shaped structure, and the second dovetail block 87 is set in the dovetail groove 85, and the first ladder body unit 81 and the third ladder body unit 83 are bound by ropes to fix the relative distance between the first ladder body unit 81 and the second ladder body unit 82, forming a structure with the second ladder body unit 82 as the treading surface and the first ladder body unit 81 and the third ladder body unit 83 as the support to increase the working height of the scaffolding.

[0121] When the first dovetail block 87 and the second dovetail block 88 slide in the dovetail groove 85, the relative position of the second ladder body unit 82 on the working structure 4 can be moved to facilitate the construction work of the construction personnel.

[0122] The working structure 4 is provided with a pedal groove corresponding to the pedal of the ladder structure 8. When the ladder is not needed, the ladder structure 8 can be stored in the upper surface of the working structure 4, that is, the first dovetail block 87 is stored in the dovetail groove 85, the side beam of the ladder body unit is stored in the storage groove 84, the pedal of the ladder structure 8 is stored in the pedal groove, and the second dovetail block 88 is located on the outside of the dovetail groove 85.

[0123] In this technical solution, the height of the working structure 4 is usually 80cm, which makes it difficult for construction workers to climb up the working structure 4 from the ground. Adding a ladder can make it easier for construction workers to climb up the working structure 4. The height of existing commercial housing is usually around 2.6 meters, and the height of construction workers is usually around 1.7 meters. The scaffolding of the present invention can meet the needs of working in ordinary commercial housing. When the working height needs to be increased in a few scenarios, it can be seen that the ladder structure 8 is bent on the working structure 4 in a U-shaped structure to increase the working height.
