At the same time, the end of the auxiliary rod 91 is rotatably connected to the round rod 13 arranged on the side close to the pull ring 7, so that when the pull rod 6 moves to the right under the tension, the auxiliary rod 91 will drive the hinged rod 12 to swing, so that the tightening arc plate 16 corresponding to the hinged rod 12 releases the pressing effect on the cover net body 4 in the positioning groove 19. Specifically, a coil spring is sleeved on the outside of the top hinged part of the hinged rod 12, and under the action of the elastic force of the coil spring, the hinged rod 12 always maintains a downward deflection movement trend, so as to always drive the tightening arc plate 16 to be pressed downward in the positioning groove 19 in the initial state.

[0030] In the embodiment of the utility model, there are two groups of connecting blocks 14, and the two groups of connecting blocks 14 are mirror-imaged on the left and right sides of the bottom end of the hinge rod 12.

Furthermore, the number of convex ridges 18 arranged on the arc-shaped outer surface of the tightening arc plate 16 is arranged in multiple groups, and the multiple groups of convex ridges 18 are distributed in a linear array. At the same time, a plurality of groups of ridge-like protrusions are arranged on the arc-shaped inner surface of the positioning groove 19 to cooperate with the convex ridges 18 to better realize the positioning function of the covering net body 4 and prevent it from lateral displacement, so as to ensure the opening state of the covering net body 4 and avoid it from being pulled or torn under the influence of external wind force, thereby affecting the coverage area of ​​the covering net body 4 and the covering and dust-proof effect.

[0031] In the utility model, when in use, after positioning the mounting frame 1, the user pulls the pull ring 7 outward to make the pull rod 6 free from the restriction of the positioning pin 8, and then rotates the pull ring 7 and the pull rod 6 to drive the winding drum 3 to rotate, thereby realizing the winding and releasing of the soil covering net body 4, thereby completing the layout of the soil covering net body 4. In this process, a protective mechanism is provided, and the hinge between the top of the hinged rod 12 and the top of the net outlet cooperates with the coil spring of its connecting part to make the hinged rod 12 move downward, thereby driving the connecting block 14 and the tightening arc plate 16 to press the soil covering net body 4 downward, so that its edge is tightly pressed in the positioning groove 19, and cooperates with the convex ridge 18 and the arc plate 16 in the positioning groove 19. The ridge-like protrusions arranged on the inner surface of the shape prevent the soil covering net body 4 from lateral displacement to ensure the open state of the soil covering net body 4 and avoid it being pulled or torn under the influence of external wind force, which affects the coverage area of ​​the soil covering net body 4 and the soil covering and dust prevention effect. Furthermore, by mirroring two groups of tightening arc plates 16 at the bottom end of the hinged rod 12, cooperating with the vortex spring 17 and the fixed shaft 15 arranged in the connecting block 14, the two groups of tightening arc plates 16 are arranged in a fork shape to better press the soil covering net body 4 inside the positioning groove 19, avoid the soil covering net body 4 from shrinking or pulling and loosening when it is pulled out for use, and ensure the shielding and dust prevention effect of the soil covering net body 4.
