[0025] In the specific implementation process, it is worth pointing out that, under the cooperation of the threaded rod 15, the fixing column 12 and the top plate 9, when the protective device is fixed, the threaded rod 15 is rotated using the handle 16, and because the outer wall of the top plate 9 is slidably connected to the bottom of the base 1, when the threaded rod 15 rotates, the fixing column 12 moves up and down instead of rotating with the threaded rod 15, so that the top plate 9 can be pressed against the ground to fix the protective device, solving the problem that the stabilizing effect of the moving wheel 10 is not good when the prior art is used, and when it is impacted, the protective device will move or even fall, causing personal safety problems to the staff;

[0026] Furthermore, both sides of the top of the top plate 9 are fixedly connected with connecting blocks 13, the outer walls of the two connecting blocks 13 are fixedly connected with slide cylinders 14, the inner wall of the slide cylinder 14 is movably connected with the limiting column 11, and the outer wall of the limiting column 11 is fixedly connected to the inner wall of the base 1;

[0027] In the specific implementation process, it is worth pointing out that, with the cooperation of the limit column 11, the slide cylinder 14 and the connecting block 13, when the top plate 9 moves, the slide cylinder 14 will be driven to move on the outer wall of the limit column 11, so that it is stable when lifting;

When replacing it, the fastening bolts 18 are removed, and the latch at the bottom of the installation frame 4 is pulled out so that it can be removed from the base 1, and the protection net 3 is replaced. After replacement, the installation frame 4 is placed on the base 1, and the latch passes through the installation frame 4, and the fastening bolts 18 above are turned to form an upward tension on the installation frame 4, so that it is more stable when fixed;

[0033] Furthermore, the two mounting posts 2 are respectively fixedly connected to the limiting blocks 5 on the sides close to each other, and the inner wall of the limiting blocks 5 is slidably engaged with the outer wall of the mounting frame 4;

[0034] In the specific implementation process, it is worth pointing out that, under the cooperation of the limit block 5, the mounting frame 4 and the mounting column 2, the limit block 5 is slidably connected to the outer wall of the mounting frame 4, which can ensure that the mounting frame 4 moves stably and does not deviate after being pulled by the fastening bolts 18;
