[0034] Working principle;

[0035] First, align the threaded tube 300 in the fixing part with the end of the tunnel segment bolt, rotate the threaded tube 300 to make it tightly screwed with the segment threaded rod 400. Since the connecting sleeve 305 can slide on the fixed rod 109, it can flexibly adapt to the segment threaded rod 400 at different positions, thereby stably fixing the abutting plate 200 at the position of the tunnel segment, and at the same time, locking the double-headed screw rod 303, pulling the fixed block 304 and the connecting block 302 inward at the same time, thereby improving the abutting force of the abutting plate 200 on the tunnel segment;

[0036] Then, the threaded rod 400 at one end of the connecting plate 105 is passed through the corresponding round hole 402 at the bottom of the support column 100, and then the nut 403 is tightened on the outside, and the clamping spring 404 is clamped into the clamping hole 401 at the end of the threaded rod 400 to prevent the nut 403 from accidentally falling off, and ensure the firmness of the connection, while the other end of the connecting plate 105 extends to the corresponding side end of the abutting plate 200, and is connected to the abutting plate 200 by rotating the fixing column 406 inserted thereon, and the limiting disc 405 on the fixing column 406 limits the displacement of the fixing column 406, ensuring that a reliable and stable connection structure is formed between the support column 100 and the abutting plate 200;

[0037] Subsequently, the one end of the insertion rod 103 at the four corners of the footboard 102 is inserted into the insertion hole 108 at the corresponding position on the top of the abutting plate 200 and the fixed plate 106 after winding to the corresponding side, and the footboard 102 is firmly fixed between the two by relying on the cooperation between the insertion rod 103 and the insertion hole 108 and the friction force increased by the winding structure, forming a working platform for personnel to stand and operate, while the support column 100, the footboard 102 and the connecting plate 105 form a triangular structure;

[0038] Finally, the recess 101 opened on the right side surface at one end of the footboard 102 can be used to place the fire extinguisher, and the several groups of holes 111 inside the recess 101 play the role of ventilation and drainage. In actual use scenarios, such as when working in a tunnel, if the fire extinguisher is placed in the recess 101, the holes 111 can ensure air circulation and prevent water vapor from accumulating in the recess 101 and causing rust on the bottom of the fire extinguisher.

[0039] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
