The adaptable base frame 1, the movable top plate 2 and the several connecting frames 3 are connected to each other by binding wires and binding holes 6 with protective nets 22. The inner side wall of the adaptable base frame 1 is provided with detachable connecting units 5. A fixing block 9 is provided between the opposing ends of the several connecting units 5. The fixing block 9 is provided with an adjusting threaded rod 4 for adjusting the height of the movable top plate 2. A snap-fit ​​block 8 is fixedly installed at the lower end of the adjusting threaded rod 4. A limit nut 7 is threadedly connected to the lower side of the adjusting threaded rod 4. After the movable top plate 2 is moved to the state where the protective net 22 is tightened, the whole device is in the shape of a four-sided pyramid.

[0029] Specifically, a matching bottom frame 1 with a side length greater than the opening in the working layer is selected. Protective nets 22 are connected between the movable top plate 2 and a connecting frame 3, between adjacent connecting frames 3, and between a connecting frame 3 and the matching bottom frame 1, all through binding holes 6. When it is necessary to protect the opening in the working layer, the entire device is placed on top of the opening and secured to the side of the clamping block 8 using a socket tool used on site. The adjusting threaded rod 4 is rotated manually or with an electric wrench to move the movable top plate 2 upward. After the movable top plate 2 moves to the tensioned state of the protective net 22, the entire device takes the shape of a four-sided pyramid. The locking limit nut 7 is used to limit and fix the adjusting threaded rod 4. The opening is protected by the protective net 22. If it is necessary to protect openings of different sizes, the matching bottom frame 1 can be replaced. The entire device is stacked when not in use, reducing the volume of the entire device after storage. Different sizes of standardized matching bottom frames 1 are made for the openings in the working layer, providing adjustable protection for openings of different sizes and improving the applicability of the entire device.

[0030] As a technical optimization of this utility model, each group of connecting units 5 includes a first connecting rod 10 fixedly installed on the side of the fixing block 9. A second connecting rod 11 is inserted into the end of the first connecting rod 10 away from the fixing block 9. A limiting bolt 12 with one end tightly abutting the side of the second connecting rod 11 is threadedly connected to one side of the first connecting rod 10. A fixing bolt 18 with one end threadedly connected to the end of the second connecting rod 11 passes through the side of the adapter base frame 1. A pressure plate 17 adapted to the side of the adapter base frame 1 is sleeved on the side of the fixing bolt 18.

[0031] Specifically, when connecting the adapter base frame 1 and the connecting unit 5 of the appropriate size, the clamping plate 17 is sleeved on the side of the end of the fixing bolt 18. The end of the fixing bolt 18 passes through the adapter base frame 1 and is threadedly connected to the end of the second connecting rod 11. The sides of the second connecting rod 11 and the clamping plate 17 are engaged with the side of the adapter base frame 1, thus completing the connection between the adapter base frame 1 and the connecting unit 5. One end of the second connecting rod 11 can slide at one end of the first connecting rod 10. The overall connecting unit 5 can be adapted to adapter base frames 1 of different sizes. Then, the limiting bolt 12 threadedly connected to the side of the first connecting rod 10 is locked. One end of the limiting bolt 12 abuts against the side of the second connecting rod 11, thereby limiting and fixing the first connecting rod 10 and the second connecting rod 11, thus improving the applicability of the overall device.

[0032] As a technical optimization of this utility model, the adjusting threaded rod 4 passes through the fixing block 9. The fixing block 9 is provided with a number of abutment plates 13 whose sides are adapted to the threads of the adjusting threaded rod 4. The fixing block 9 is provided with a moving groove 14 adapted to the abutment plates 13.

A spring 16 is fixedly installed between one side of the moving rod 15 and the side of the fixing block 9.

[0033] Specifically, when it is necessary to lift the movable top plate 2, several movable rods 15 are pulled simultaneously away from the fixed block 9. When the movable rods 15 move, they cause the abutment plate 13 to move away from the adjusting threaded rod 4. The threads on the side of the abutment plate 13 disengage from the threads on the side of the adjusting threaded rod 4, and the spring 16 is stretched. The adjusting threaded rod 4 passes through the fixed block 9. The hand holds the adjusting threaded rod 4 and moves it upward quickly, pushing the movable top plate 2 upward. When the movable top plate 2 moves to the point where it cannot be pushed any further, several movable rods 15 are released. At this time, the tension of the spring 16 drives the movable rods 15 to move towards the fixed block 9. The threads on the side of the abutment plate 13 engage with the threads on the side of the adjusting threaded rod 4. Then, the adjusting threaded rod 4 is rotated again by rotating the locking block 8 to tighten the protective net 22. By quickly adjusting the position of the adjusting threaded rod 4, it is easy to quickly adjust the overall device.

[0034] As a technical optimization of this utility model, a positioning post 19 is fixedly installed on the upper end of the adjusting threaded rod 4, and a positioning ring 20 adapted to the positioning post 19 is fixedly installed on the lower part of the movable top plate 2. A rotary bearing 21 is sleeved on the side of the positioning post 19. The rotary bearing 21 is located between the positioning ring 20 and the adjusting threaded rod 4. The positioning post 19 at one end of the adjusting threaded rod 4 is inserted into the positioning ring 20 to limit the position of the adjusting threaded rod 4. The rotary bearing 21 is a thrust ball bearing, which facilitates the rotation of the adjusting threaded rod 4.
