A fixing pipe 11 is fixedly connected to one side of the connecting plate 14. A locking groove 10 is fixedly connected to one end of the fixing pipe 11. First fixing rods 12 are movably connected to both ends of the locking groove 10. Two sets of first fixing rods 12 are fixedly connected at one end. A triangular slider 13 is connected. Through the engagement of the first engaging head 7, the second engaging head 8, and the engaging groove 10, the first engaging head 7 and the engaging groove 10 cooperate with each other, thereby fixing the first engaging head 7 with the engaging groove 10. Through the engagement of the first fixing rod 12 and the triangular slider 13, the triangular slider 13 moves, thereby limiting the first engaging head 7 with the triangular slider 13. Through the engagement of the second fixing rod 16, the first connecting ring 17, the second connecting ring 18, and the third fixing rod 19, the first connecting ring 17 and the second connecting ring 18 interlock, thereby fixing the first protective net frame 2 and the second protective net frame 4.

[0026] Please see Figure 2 and Figure 3 The connecting tube 5 has a cavity inside, and the cavity cooperates with the connecting rod 6. By setting the above structure, the connecting rod 6 is accommodated by the cavity inside the connecting tube 5, so that the connecting rod 6 has space to move.

[0027] Please see Figure 1 The bottom of the first protective net frame 2 and the second protective net frame 4 are respectively fixedly connected to two sets of fixing plates 15, and two sets of threaded holes are opened on the four sets of fixing plates 15. By setting the above structure, the position of the first protective net frame 2 and the second protective net frame 4 is fixed by the fixing plates 15 at the bottom of the first protective net frame 2 and the second protective net frame 4, and the position of the fixing plates 15 is fixed by nuts.

[0030] The working principle of the utility model is as follows: in use, the number of protection devices is determined according to the required safety protection distance, and the protection devices are connected together and placed at the position requiring protection.

[0031] The position of the first protection net frame 2 is moved, so that the first clamping head 7 enters the fixing pipe 11 through the clamping groove 10; in the moving process of the first clamping head 7, the first clamping head 7 extrudes the triangular slide block 13, so that the triangular slide block 13 limits the first clamping head 7; at this time, the first protection net frame 2 and the second protection net frame 4 are connected together; the above operation is repeated to connect multiple groups of the first protection net frame 2 and the second protection net frame 4 according to the required length of the protection net, so that the position of the protection net building is protected.

[0032] At this time, the first connecting ring 17 passes through the second connecting ring 18, so that the connection between the first protection net frame 2 and the second protection net frame 4 is more stable, and the personal safety of passing pedestrians and staff is avoided from being affected due to the inclination of the protection device caused by environmental factors.

[0033] Meanwhile, the bolt passes through the threaded hole in the fixing plate 15 fixed at the bottom of the first protection net frame 2 and the second protection net frame 4, so that the protection device is fixed to the ground, and the protection device is avoided from shaking due to external factors.

[0034] When the protection device needs to be removed, the connecting rod 6 is pushed to drive the second clamping head 8 to move to the position of the clamping groove 10; at this time, the triangular slide block 13 clamps the second clamping head 8, and then the connecting rod 6 is reversely moved; at this time, the connecting rod 6 drives the first clamping head 7 to move, until the sliding block 9 cooperates with the cavity opened on one side of the first clamping head 7; at this time, the connecting rod 6 drives the first clamping head 7 out of the clamping groove 10, and the limiting of the first clamping head 7 by the triangular slide block 13 is released; meanwhile, the nut is screwed out, and the protection device is removed by repeating the above operation.
