Two sliding grooves 18 are formed on the opposite surfaces of the second mounting posts 4 on both sides. The two sliding grooves 18 are parallel to each other, with the top of the front sliding groove 18 open and the bottom of the rear sliding groove 18 open. The left and right ends of the first protective net 1 and the second protective net 2 are respectively installed in the two sliding grooves 18 of the second mounting posts 4 on the left and right sides via sliders 13. Transmission gears 15 are rotatably installed in each of the second mounting posts 4. Each transmission gear 15 is respectively engaged with the first protective net 1 and the second protective net 2. The transmission racks 14 at both ends of the net 2 are engaged, and the transmission racks 14 can be driven by the rotation of the transmission gears 15. The upper and lower ends of the second mounting post 4 are fixedly installed with locking blocks 16. The upper and lower ends of the second mounting post 4 are respectively provided with first mounting posts 3 and third mounting posts 5. The lower end of the first mounting post 3 and the upper end of the third mounting post 5 are provided with locking grooves. The upper and lower ends of the second mounting post 4 are fixedly installed in the locking grooves at the lower end of the first mounting post 3 and the upper end of the third mounting post 5 respectively by locking blocks 16 and fastening bolts 20. The opposing surfaces of the first mounting posts 3 and the third mounting posts 5 on both sides are provided with a transmission groove 19. The transmission groove 19 on the first mounting post 3 is connected to the sliding groove 18 on the front side of the second mounting post 4, and the transmission groove 19 on the third mounting post 5 is connected to the sliding groove 18 on the rear side of the second mounting post 4. This arrangement can better cooperate with the first protective net 1 and the second protective net 2 to work.

[0023] A pressure plate 8 is fixedly installed at the bottom of the first protective net 1. A gripping opening 9 is provided in the middle of the pressure plate 8. This setting can better control the movement of the first protective net 1.

[0024] A limiting groove 17 is provided in the middle of the transmission gear 15, which can fix the transmission gear 15. Through holes 22 are provided on the opposite surfaces of the two second mounting posts 4. Mounting grooves 21 are provided on the front and rear sides of the through holes 22. Limiting components are installed in the through holes 22, and the limiting components cooperate with the limiting grooves 17 of the transmission gear 15 and the mounting grooves 21 of the through holes 22 respectively.

[0025] The limiting assembly includes a limiting rod 23, a plug 26, a limiting plate 25, a fixing plate 24, and fixing bolts. A plug 26 is fixedly installed at one end of the limiting rod 23, serving as a crucial connection. Limiting plates 25 are installed on both the upper and lower sides of the other end of the limiting rod 23. Fixing plates 24 are fixedly installed on both the front and rear sides of the plug 26. The limiting rod 23, in conjunction with the limiting plate 25 and fixing plate 24, is installed within the through hole 22. The limiting plate 25 on the limiting rod 23 engages with the limiting groove 17 in the middle of the transmission gear 15, thus fixing the transmission gear 12. The position of the limiting groove 17 on the transmission gear 15 is the same when the first protective net 1 and the second protective net 2 are not deployed and when they are deployed. The fixing plate 24 on the plug 26 engages with the mounting groove 21 of the through hole 22. The fixing plate 24 on the plug 26 is fixedly installed within the mounting groove 21 of the through hole 22 using fixing bolts, thus fixing the limiting rod 23.

[0026] The top of the first mounting column 3 is fixedly installed with a top cover 6, which can play a protective role. The bottom of the third mounting column 5 is fixedly installed with a support leg 7, which can make the device more stable and increase the reliability of the device.

[0027] Each of the third mounting posts 5 has a baffle 12 fixedly installed on its opposite surface. The baffle 12 has a through groove, and the through groove has an insert plate 11 installed inside. The top of the two insert plates 11 is fixedly installed with a connecting plate 10. The connecting plate 10 contacts and cooperates with the pressure plate 8 at the bottom of the first protective net 1. This arrangement can limit the pressure plate 8 on the first protective net 1 to a certain extent, and can also connect the third mounting posts 5 on both sides to increase the stability of the device.

[0028] Working principle: When transportation is required, the first protective net 1, the second protective net 2, the third mounting post 5, and the connecting plate 10 on the first mounting post 3 and the second mounting post 4 are transported respectively; when installation is required, the first mounting post 3, the second mounting post 4, and the third mounting post 5 are fixedly connected in sequence, the insert plates 11 at both ends of the connecting plate 10 are installed into the baffles 12 on the third mounting post 5, the limiting component is pulled out of the second mounting post 4, the plug 26 is separated from the through hole 22, the fixing plate 24 is separated from the mounting groove 21, and the limiting plate 25 is separated from the limiting groove 17. At this time, the control gripping hole moves the first protective net 1 downward, and the first protective net 1 on both sides of the first protective net 1... The transmission rack 14 drives the transmission gear 15 to rotate. At the same time, the transmission gear 15 drives the transmission racks 14 on both sides of the second protective net 2 to move upward until the pressure plate 8 presses down on the connecting plate 10. At this time, the position of the limiting groove 17 on the transmission gear 15 is the same as the position of the limiting groove 17 when the limiting component and the transmission gear 15 are just separated. Insert the limiting component into the second mounting post 4, mate the plug 26 with the through hole 22, mate the fixing plate 24 with the mounting groove 21, tighten the fixing bolts, mate the limiting plate 25 with the limiting groove 17, and fix the transmission gear 15, thereby fixing the first protective net 1 and the second protective net 2. The installation of the protective net is completed.
