[0047] When the nail-in casing 1 is in use, the nail-in casing 1 is pre-penetrated through the slope protection net and nailed into the ground for fixation. The connecting plate 3 provided on the nail-in casing 1 can fix the rectangular cover plate A2 on the body of the nail-in casing 1, which is an integral structure with the nail-in casing 1. After the nail-in casing 1 is installed and buried, the operating screw 4 can be rotated and installed from the top end. The rotating sleeve installed on the operating screw 4 can cooperate with the operating screw 4 to rotate. The rectangular cover plate B6 installed on the rotating collar 5 can be further screwed and pressed down on the operating screw 4. During the pressing process of the rectangular cover plate B6, it can cooperate with the rectangular cover plate A2 to tightly fix the slope protection net, improving the stability of the slope protection net.

[0048] A threaded space 7 is provided inside the nail-in casing 1. The threaded space 7 is funnel-shaped. A limiting groove 8 is opened at the bottom of the threaded space 7. Locking structures 9 are provided on both sides of the threaded space 7. The funnel-shaped threaded space 7 can facilitate the cooperation with the operating screw 4. The locking mechanisms provided on both sides of the threaded space 7 can be pushed by the operating screw 4 to lock the nail-in casing 1.

[0049] The locking structure 9 includes three groups of through grooves 10. The through grooves 10 penetrate the nail-in casing 1. Fixed pins 11 are respectively installed inside the through grooves 10. A push rod 12 is installed on the fixed pin 11. A strengthening head 13 is provided at the end of the push rod 12. The tapered threaded rod 14 at the bottom of the operating screw 4 can cooperate with the funnel-shaped threaded space 7. During the screwing process of the operating screw 4, the tapered threaded rod 14 can push the strengthening head 13 provided inside the through groove 10, and at the same time push the push rod 12 outwards until the abutting head 15 extends into the bottom of the threaded space 7, driving the fixed pin 11 installed on the push rod 12 to make the fixed pin 11 extend out of the nail-in casing 1, increasing the nailing effect and anti-pulling property, and making the nail-in casing 1 more stable.

[0050] The rectangular cover plate A2 and the rectangular cover plate B6 are installed in parallel. Pressure net supports 16 are installed between the rectangular cover plate A2 and the rectangular cover plate B6. The rectangular cover plate A2 and the rectangular cover plate B6 can compact the slope protection net, increasing the contact area with the pressure net supports 16 and improving the stability of the slope protection net.

[0051] The pressure net support 16 includes an annular frame body 17. An extended eaves 22 is provided outside the annular frame body 17. A pressure strip 18 is provided inside the annular frame body 17. The annular frame body 17 and the extended eaves 22 can increase the contact area with the slope protection net. The pressure strip 18 provided inside the annular frame can also compact the slope protection net, increasing the fixing effect on the slope protection net.

[0052] A tapered drill bit 19 is provided at the bottom end of the nail-in casing 1. A hardened layer 20 is provided outside the tapered drill bit 19. The tapered drill bit 19 provided on the nail-in casing 1 can drill into the ground, and the hardened layer 20 provided at the top of the drill bit can prevent the nailed tapered drill bit 19 from deforming.

[0053] An elastic element 21 is provided inside the fixing pin 11 and the through groove 10. The elastic element 21 is installed in parallel at the upper and lower ends of the push rod 12. The elastic element 21 between the fixing pin 11 and the through groove 10 can prevent the fixing pin 11 from disengaging from the inside of the through groove 10, and at the same time can retract the fixing pin 11 after the tapered threaded rod 14 is rotated and removed.

[0054] By driving the driving sleeve 1 through the slope protection net and fixing it to the ground, after the operating screw 4 installed on the driving sleeve 1 is screwed in, the locking structure 9 in the threaded space 7 of the driving sleeve 1 can be further pushed forward. The cooperation between the fixing pin 11 and the push rod 12 provided in the locking structure 9 can increase the anti-pulling force of the driving sleeve 1, making the fixing of the driving sleeve 1 more stable. The rectangular cover plate A2 and the rectangular cover plate B6 provided on the driving sleeve 1 and the operating screw 4 cooperate with the net pressing bracket 16 to increase the contact area with the slope protection net, improve the stability of the slope protection net, and enhance the protection ability of the slope protection net.
