A convex groove 8 is provided at the opposite end of each of the two horizontal plates 7. A convex strip 9 is slidably provided inside each of the two convex grooves 8. The two convex strips 9 are fixedly connected to the top and bottom ends of the dust control net body 1, respectively. The side end of the second vertical rod 3 is fixedly connected to the side end of the two convex strips 9. A first screw 10 that mates with the convex strip 9 is threaded onto the horizontal plate 7.

[0030] Specifically, the dustproof net body 1 is wound around the winding roller 5, and the convex strip 9 slides inside the convex groove 8, which facilitates the adjustment of the length between the convex strip 9 and the horizontal plate 7. At the same time, the dustproof net body 1 is wound off the winding roller 5, which allows for the adjustment of the spacing between the first vertical rod 2 and the second vertical rod 3, and facilitates the adjustment of the length of the dustproof net body 1. This makes it easy to adjust the length of the dustproof net body 1 appropriately according to the different lengths of the municipal construction site, reducing its limitations in use.

[0031] Please see Figures 1-3 The bottom ends of the first vertical rod 2 and the second vertical rod 3 are provided with adjustment grooves 11. Adjustment plates 12 are slidably arranged inside the two adjustment grooves 11. The bottom ends of the two adjustment plates 12 are fixedly connected to mounting plates 13. The mounting plates 13 are provided with multiple mounting holes 14. Ground nails pass through the inside of the mounting holes 14 and are inserted into the ground to fix the mounting plates 13 to the ground. The first vertical rod 2 and the second vertical rod 3 are threaded with second screws 15 that cooperate with the adjustment plates 12 to facilitate the fixing of the adjustment plates 12.

[0032] Specifically, by sliding the adjusting plate 12 inside the adjusting groove 11, it is convenient to adjust the length of the adjusting plate 12 outside the adjusting groove 11, and to adjust the distance between the mounting plate 13 and the first vertical rod 2 and the second vertical rod 3. This facilitates the adjustment of the height of the first vertical rod 2, the second vertical rod 3 and the dustproof net body 1, and makes it easy to adjust the dustproof net body 1 to different heights near the construction position, thus improving its practicality.

[0033] Please see Figure 1 , Figure 2 and Figure 5 A sliding groove 16 is provided on the bottom side of the convex groove 8. An extrusion plate 17 is slidably arranged inside the sliding groove 16.

Multiple fixing grooves 25 that are adapted to the second screw 23 are evenly arranged on the outer side wall of the second handle 21, which facilitates the fixing of the second handle 21 and the winding roller 5.

[0036] Specifically, by rotating the winding roller 5 with the second throttle 21, the dustproof net body 1 is wound around the winding roller 5, so that the dustproof net body 1 is in a taut state. Then, the second screw 23 is rotated clockwise, and the second screw 23 moves relative to the fixing block 22 to the side closer to the second throttle 21, and the second screw 23 is inserted into the corresponding fixing groove 25, so as to fix the second throttle 21 and the winding roller 5.

[0037] In summary, when using the overall equipment:

[0038] First, fix the mounting plate 13 corresponding to the first vertical rod 2 to the ground at the corresponding position using ground nails. Then, rotate the second screw 23 counterclockwise to separate the second screw 23 from the corresponding fixing groove 25. Then, loosen the first screw 10 and pull the second vertical rod 3 to move it. The second vertical rod 3 pulls the two convex strips 9 to move, and at the same time, pulls the dustproof net body 1 to move, so that the dustproof net body 1 is unwound from the winding roller 5. Adjust it to a suitable length, then fix the mounting plate 13 corresponding to the second vertical rod 3 to the ground using ground nails. Then, tighten the first screw 10 so that the side end of the first screw 10 abuts against the side end of the convex strip 9 to fix the convex strip 9. Then, rotate the second handle 21, which drives the winding roller 5 to rotate, so that the dustproof net body 1 is wound around the winding roller 5, so that the first vertical rod 2 and the second vertical rod 3 are unwound from the winding roller 5. The dustproof net body 1 between the rods 3 is in a taut state. Then, the second screw 23 is rotated clockwise. The second screw 23 moves relative to the fixing block 22 towards the side closer to the second handle 21 and inserts into the corresponding fixing groove 25 to fix the second handle 21 and the winding roller 5. Then, the first screw 18 is rotated clockwise. The first screw 18 moves relative to the horizontal plate 7 into the convex groove 8. The first screw 18 drives the extrusion plate 17 to move, so that the extrusion plate 17 extrudes and fixes the dustproof net body 1 inside the convex groove 8. Then, the second screw 15 is loosened. The dustproof net body 1 is adjusted to a suitable height by sliding the adjusting plate 12 inside the adjusting groove 11. Then, the second screw 15 is tightened so that the side end of the second screw 15 abuts against the side end of the adjusting plate 12 to fix the adjusting plate 12.
