[0034] In this technical solution, during use, the square frame is first welded to the covering bottom surface, and then the upper slide bar and the lower slide bar are respectively welded to the corresponding edges of the square frame, and then the fixed vertical rod is welded to the ends of the upper slide bar and the lower slide bar, and then the connecting plate is welded to the fixed vertical rod, and the fixing pin is inserted into the hole of the connecting plate, and the pin shaft overhead hole is inserted into the R pin for fixing; then the longitudinal rod is welded to the connecting plate, and then the cross bar is vertically welded to the longitudinal rod to obtain an integrated hole protection device; then this device is covered on the hole to be protected, and the upper slide bar and the lower slide bar are slid according to the size of the hole to adjust the bottom surface area; if transportation is required, the upper slide bar and the lower slide bar are slid to shrink the upper bottom surface and the lower bottom surface into the covering bottom surface, and then the guardrail is folded inward, which reduces the structure as a whole, reduces the space occupied by the structure, and facilitates transportation;

[0035] The technical solution has the following beneficial effects: by designing a square frame, an upper slide bar, a lower slide bar, an upper bottom surface, a lower bottom surface and a covered bottom surface, the upper slide bar and the lower slide bar can be slid to adjust the bottom surface area according to the size of the hole to be protected to adapt to holes of different sizes; secondly, by designing a fixed vertical pole and a guardrail hinged to the fixed vertical pole, the fixed vertical pole is welded to the ends of the upper slide bar and the lower slide bar, so that on the one hand an integrated hole protection device is formed, and on the other hand the guardrail can be folded inward, so that the device can be easily transported, and is simple to operate and install.

[0036] In another technical solution, the height of each fixed pole 10 located in the same direction on the same side is consistent, and the heights of the fixed poles 10 located in different directions on different sides are inconsistent with each other.
