[0032] Refer to Figure 4 , a fixed column 404 is fixedly connected to the inner cavity of the connecting plate 403. One side of the fixed column 404 is rotatably connected to a rotating wheel 402 through a bearing. A guide rod 401 is rotatably connected to the inner cavity of the rotating wheel 402, and the guide rod 401 is fixedly connected to the inner cavity of the L-shaped plate 109. Through the setting of the fixed column 404, it supports the rotating wheel 402, enabling the fixed column 404 to stably rotate. Also, through the coordinated use of the guide rod 401 and the rotating wheel 402, the sliding side 101 and the inner connecting plate 104 can stably move on the top of the L-shaped plate 109, facilitating the demolding of the staircase;

[0033] Refer to Figure 3 and Figure 8, the operating mechanism 5 includes a workbench 501 and a support sleeve 507. The support sleeve 507 is fixedly connected to the back side of the top of the chassis 108. The number of support sleeves 507 is several. The workbench 501 is movably connected to the back side of the second fixed pull rod 204. The front side of the bottom of the workbench 501 is fixedly connected with a first rotating plate 502. The inner cavity of the first rotating plate 502 is rotationally connected with a second rotating plate 503 through a pin. The second rotating plate 503 is fixedly connected to the back side of the second fixed pull rod 204. Through the setting of the workbench 501, operations such as the installation, disassembly, and adjustment of the mold are made more convenient and efficient, which helps to shorten the production cycle and improve production efficiency. Also, through the coordinated use of the first rotating plate 502 and the second rotating plate 503, the workbench 501 is convenient for installation and disassembly;

[0034] Refer to Figure 8 , the back side of the bottom of the workbench 501 is fixedly connected with a third rotating plate 504. The inside of the third rotating plate 504 is rotationally connected with a fourth rotating plate 505 through a pin. The inside of the fourth rotating plate 505 is fixedly connected with a support column 506. The bottom of the support column 506 is inserted into the inner cavity of the support sleeve 507. Through the setting of the support column 506, the position of the workbench 501 is supported to prevent the workbench 501 from falling during use. Also, through the setting of the support sleeve 507, the position of the support column 506 is fixed, thereby improving the stability of the workbench 501;

[0035] Refer to Figure 6 , the surface of the sliding side 101 is fixedly connected with side plates 6. The number of side plates 6 is several. The surface of the side plates 6 is movably connected with triangular concave plates 7. One side of the triangular concave plates 7 is fixedly connected to the surface of the fixed side 102. Through the coordinated use of the side plates 6 and the triangular concave plates 7, the smoothness of the sliding side 101 during movement can be observed. When the side plates 6 are stably engaged with the triangular concave plates 7, it indicates that the movement is relatively smooth without deviation. Otherwise, there is deviation;

[0036] Refer to Figure 1 , both sides inside the fixed side 102 are movably connected with hole-retaining columns 107. The number of hole-retaining columns 107 is two. The back side of the fixed side 102 is provided with forming grooves 106. The number of forming grooves 106 is several. Through the setting of the forming grooves 106, the formed staircase 103 is quickly formed. Also, through the setting of the hole-retaining columns 107, holes are opened on both sides of the formed staircase 103, facilitating subsequent installation by construction workers.

[0037] Working principle: After the formed staircase 103 solidifies, first rotate the first screw sleeve 203. When the first screw sleeve 203 rotates, it moves on the surface of the first pull rod 202, and then the first screw sleeve 203 gradually stops contacting the second fixed pull rod 204. Subsequently, rotate the second screw sleeve 207 to make it move on the surface of the second pull rod 206 until the second screw sleeve 207 stops contacting the surface of the first fixed rod 201. Then rotate the first pull rod 202 to make the first pull rod 202 rotate inside the inner cavity of the first fixed rod 201 until it disengages from the inside of the second fixed pull rod 204. Then rotate the second pull rod 206 to make the second pull rod 206 disengage from the inner cavity of the first fixed rod 201. When the first pull rod 202 disengages from the inner cavity of the second fixed pull rod 204 and the second pull rod 206 disengages from the inner cavity of the first fixed rod 201, rotate the fastening pull rod 303 to make the fastening pull rod 303 disengage from the inside of the positioning plate 304. At this time, the sliding side 101 can be pulled for demoulding. The movement of the sliding side 101 drives the side plate 6 to disengage from the inside of the triangular concave plate 7. At this time, the runner 402 starts to rotate on the surface of the guide rod 401. Through the setting of the guide rod 401, it plays a guiding role for the runner 402, enabling the runner 402 to stably move on the surface of the guide rod 401 and preventing the runner 402 from deviating from the preset track during movement. As the runner 402 rotates, it drives the connecting plate 403 to move. The movement of the connecting plate 403 drives the inner connecting plate 104 to move. Through the movement of the inner connecting plate 104, it drives the sliding side 101 to move, and then the inner connecting plate 104 disengages from the surface of the fixed side 102. At this time, the staff can take out the solidified fixed side 102. If a new formed staircase 103 needs to be poured, push the connecting plate 403 to restore the sliding side 101 and the inner connecting plate 104 to their original positions.

[0038] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
