By rotating and opening the box door 55, the structure inside the shell 1 can be inspected, and the mesh pad body 7 can be installed or disassembled.

[0038] In summary, the working principle of the present invention is as follows: when in use, the net pad is carried to the top of the slope, and the button 20 is pressed. The button 20 drives the tooth plate 21 to descend, so that the gear 22 and the gear 3 23 rotate. The gear 22 makes the pressing plate 19 rise, and the gear 3 23 drives the rotating wheel 24 to rotate, so that the eccentric rod 25 and the connecting rod 26 are displaced. The connecting rod 26 presses the card block 27 to slide outward. Under the limit of the lifting slot 28, the card block 27 cannot move outward. The force of pressing the button 20 will make the lifting member 13 slide downward. When the card block 27 moves out from under the lifting slot 28, the card block 27 will slide out to limit the lifting member 13 so that it cannot slide upward and reset. When the lifting member 13 descends, the inclined slot 15 The inner wall will squeeze the slide bar 16, causing the tooth plate 12 to move to the left. The tooth plate 12 rotates the gear 5 through the tooth groove, driving the pawl 6 to rotate. The pawl 6 moves away from the ratchet 4 and no longer engages with the ratchet 4. At this time, according to the angle and length of the slope, the structural position of the roller 44 and the like is adjusted, the bolt 35 is turned, and the two cross frames 32 are slid out to the right. Then the two rotating blocks 37 are turned to rotate the screw 36. Under the condition that the outer surface of the shell 1 and the lower inner surface of the support leg 2 fit the cross frame 31, the cross frame 31 will drive the cross frame 32 to slide to the right, causing the roller 44, the sprocket 45, and the rope drum 2 43 to move to the right. After the roller 44 moves to the position just above the road and the slope, , turn the crank 41 to make the rotating rod 38 drive the rope drum 39 to rotate, reel in the pull rope 40, and rotate the rope drum 2 43, the drum 44, the sprocket 45, and the rotating rod 2 42. Under the meshing connection between the sprocket 45 and the mounting ring 10, the mesh mat body 7 will be driven to move to the right. Under the pulling, the reel 3 and the ratchet 4 rotate to extend the mesh mat body 7. The right end of the mesh mat body 7 slowly falls to avoid the sharp stones, dead branches and other debris on the slope to prevent the net body 8 from being hooked and unable to be laid smoothly. The personnel on standby at the highway below temporarily fix the bottom of the mesh mat body 7, and then slide the cross frame 1 31 and the cross frame 2 32 back. The mesh mat body 7 will now fit with the slope surface, and the personnel will cut the mesh mat body 7 , insert the ground nail through the mounting ring 10 into the slope to fix the mesh mat body 7 on the slope; press the button 19 to drive the gear 2 22 to make the tooth plate 2 21 rise, and make the gear 3 23 and the rotating wheel 24 rotate, and the two blocks 27 slide inward relative to each other. At this time, the spring 17 pushes the tooth plate 12 to move to the left, and the lifting member 13 moves up through the slide bar 16 and the inclined slot 15, and drives the gear 1 5 to make the bottom end of the pawl 6 engage with the ratchet 4, and limit the one-way rotation of the reel 3, so that when the mesh mat body 7 is rotated to be wound up, it can only be wound up and rotated. After winding up, the mesh mat body 7 will not stretch when it shakes arbitrarily under the limit of the pawl 6, so that the mesh mat body 7 can be better stored and placed.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
