[0027] Specifically, the first vertical cylinder 1 can be used to fix the first support plate 3 and the first fixed plate 4, and the second vertical cylinder 11 can be used to fix the second fixed plate 13 and the second support plate 12. The first support plate 3 and the second support plate 12 are used to support the protective net as a whole. The protective net main body 10 is used to enclose the surrounding construction area to ensure the safety management and construction progress of the construction site. By turning the knob 6, the winding column 9 can be rotated and the winding column 9 can be rotated inside the first fixed plate 4, and then the protective net main body 10 can be rolled up, so that the use length of the protective net main body 10 can be adjusted.

[0028] Reference Figure 3 and Figure 5 The outer wall of the second fixing plate 13 is fixedly connected with a T-shaped block 24, and the interior of the first fixing plate 4 is slidably connected with a long sliding column 19;

[0029] Specifically, the second fixing plate 13 can fix the T-shaped block 24 .

[0030] Reference Figure 3-Figure 6One end of the long sliding column 19 is fixedly connected to a fixed block 20, and the outer wall of the long sliding column 19 is fixedly connected to a limiting plate 23; the outer wall of the long sliding column 19 is slidably connected to a second spring 22; one end of the second spring 22 is fixedly connected to the outer wall of the fixed block 20; the other end of the second spring 22 is fixedly connected to the inner wall of the first fixed plate 4; the outer wall of the fixed block 20 is rotatably connected to a moving wheel 21, and the outer wall of the moving wheel 21 is connected to the inner wall of the first fixed plate 4;

[0031] Specifically, one end of the second spring 22 is fixedly connected to the outer wall of the fixed block 20, and the other end of the second spring 22 is fixedly connected to the inner wall of the first fixed plate 4 to prevent the long sliding column 19 from rotating when sliding inside the first fixed plate 4. The moving wheel 21 can improve the smoothness of the movement of the fixed block 20.

[0032] Working principle: When the protective net is needed, it is only necessary to press the special-shaped strip 15 to cause the special-shaped strip 15 to drive the rotating column 14 to rotate on the inner wall of the rectangular box 5, thereby causing the smooth column 18 to slide on the outer wall of the special-shaped strip 15 and also slide on the inner wall of the rectangular box 5 and press the first spring 17 to contract under force. At this time, the limit block 16 fixedly connected to the outer wall of the special-shaped strip 15 will slide out from the inner wall of the card slot 8 opened on the outer wall of the rotating wheel 7. When it slides out completely, the knob 6 is turned to drive the rotating wheel 7 to rotate and then drive the winding column 9 to rotate. The protective net body 10 is rolled up or unrolled inside the first fixing plate 4. When the protective net body 10 is adjusted to the required length, the special-shaped strip 15 is no longer pressed. At this time, the first spring 17 will rebound to push the special-shaped strip 15 to drive the rotating column 14 to rotate on the inner wall of the rectangular box 5 again, thereby prompting the limit block 16 to slide into the inner wall of the card slot 8 again to limit the card slot 8, thereby achieving the effect of adjusting the length of the protective net body 10 according to needs. When the protective net needs to be folded up as a whole, the rotating column 14 is rotated. The rotating knob 6 causes the winding column 9 to rotate to wind up the protective net body 10. At this time, the protective net body 10 will drive the second vertical cylinder 11 and the second fixed plate 13 to move toward the direction of the first vertical cylinder 1. During the movement, the T-shaped block 24 fixedly connected to the outer wall of the second fixed plate 13 will contact with the fixed block 20 and slide on the outer wall of the fixed block 20. When the T-shaped block 24 slides on the outer wall of the fixed block 20, the fixed block 20 will be forced to move, and the fixed block 20 will drive the long slide column 1 in the process of movement. The second spring 22 which slides inside the first fixing plate 4 and pushes the outer wall of the long sliding column 19 to slide on the outer wall of the long sliding column 19 and contracts. When the T-shaped block 24 completely slides over the outer wall of the fixed block 20, the fixed block 20 will no longer be stressed. At this time, the second spring 22 will rebound and reset, and then push the fixed block 20 to rebound and fix the T-shaped block 24, thereby completing the overall folding of the protective net. The operation is convenient, and it is convenient to transport and move after folding, further improving the practicality of the protective net.
