The adjustment mechanism comprises a rotating shaft 25 rotatably installed on the pad 22, both ends of the rotating shaft 25 penetrate the pad 22 and extend into the receiving groove 101, and the rotating shaft 25 is provided with a plurality of holes 202. The upper and lower ends are respectively fixedly connected with a knob 26 and a circular gear 24. An L-shaped limit groove 222 is opened at the lower end of the pad 22. The length of the L-shaped limit groove 222 is set greater than the length of the accommodating groove 101. Two L-shaped brackets 23 are slidably installed in the L-shaped limit groove 222. The lower ends of the two L-shaped brackets 23 are fixedly connected with a long tooth rod 231, and the long tooth rod 231 is meshed with the circular gear 24. The sides of the two L-shaped brackets 23 away from each other are respectively tightly attached to the inner walls of the two sides of the accommodating groove 101 and are slidably connected to the accommodating groove 101.

[0030] Specifically, when the floor body 20 on the stair body 10 is translated, the rotating knob 26 is turned to make the rotating shaft 25 drive the circular gear 24 to rotate. Since the long tooth rod 231 is restricted in the accommodating groove 101, the circular gear 24 rotates on the long tooth rod 231, so that the pad 22 pushes the floor body 20 to move horizontally on the stair body 10. At the same time, the two L-shaped brackets 23 slide relatively in the L-shaped limiting groove 222 to adjust the position of the floor body 20 on the stair body 10 so that the floor body 20 can be accurately docked with the stair body 10.

[0031] Reference Figure 2 and Figure 4As shown, a circular shaft 28 is rotatably installed on one side of the pad 22 close to the rotating shaft 25, both ends of the circular shaft 28 pass through the pad 22, and the upper and lower ends of the pad 22 are respectively fixedly connected to a limit block 27 and a pull block 281, one end of the limit block 27 is slidably engaged with the tooth groove on the circular gear 24. Before turning the knob 26, it is necessary to pull the pull block 281 first so that the circular shaft 28 drives one end of the limit block 27 to disengage from the tooth groove of the circular gear 24 to release the lock of the circular gear 24. After adjusting the position of the floor body 20, push the pull block 281 so that the circular shaft 28 pushes the limit block 27 so that one end of the limit block 27 is engaged in the tooth groove of the corresponding circular gear 24 to lock the circular gear 24 to prevent the circular gear 24 from loosening and causing the floor body 20 to shift when the floor body 20 is affected by external force.

By pressing the slide rod 32, the first baffle plate 321 and the second baffle plate 322 are vertically moved downward in the circular groove 301, and further the ends of the two L-shaped clamping blocks 31 close to each other are deflected downward, so that the two L-shaped clamping blocks 31 are contracted away from each other in the two openings 302, thereby facilitating the disassembly and assembly of the floor slab body 20.

[0038] Reference Figure 3 and Figure 5 As shown, the L-shaped clamp 31 is composed of two mutually perpendicular plate structures, the connection between the two plate structures is rotatably installed at the lower end of the opening 302, the first baffle 321 and the second baffle 322 are both circular, and the diameter of the second baffle 322 is smaller than the diameter of the first baffle 321.

[0039] Specifically, after the positioning between the floor body 20 and the stair body 10 is completed, the connecting column 30 is inserted into the corresponding holes of the floor body 20 and the pad 22. When the connecting column 30 enters the hole, it is necessary to first press the sliding rod 32 to make the first baffle 321 and the second baffle 322 move vertically downward in the circular groove 301, and further make the ends of the two L-shaped clamping blocks 31 close to each other deflect downward, so that the two L-shaped clamping blocks 31 are contracted away from each other in the two openings 302. When the lower end of the connecting column 30 passes through the connecting hole 104 and enters the second elongated groove 103, the connecting column 30 is loosened. The sliding rod 32 is opened, and under the elastic force of the second spring 33, the first baffle plate 321 and the second baffle plate 322 push the ends of the two L-shaped clamps 31 that are close to each other to flip upward, so that the ends of the two L-shaped clamps 31 that are away from each other are respectively unfolded from the two openings 302 and engaged in the corresponding slots 105, and then the pressing block 34 is driven to rotate on the connecting column 30 by rotating the knob handle 341 to squeeze the pad 22, so that the connecting column 30 slides upward, and further through the cooperation of the two L-shaped clamps 31, the floor body 20 and the stair body 10 can be squeezed and fixed together.
