A second installation slot 45 is penetrated and opened on the outer wall of the side of the limit card block 44. The first installation slot 43 and the second installation slot 45 are slidably installed with the limit pin 46. Threaded columns 47 are symmetrically arranged on the outer walls of both sides of the limit pin 46, and threaded caps 48 are threadedly installed on the outside of the threaded columns 47; When it is necessary to assemble and install the fence frame 1 with the support column 2 and the adjustment box 3 together, first, the fence frame 1 needs to be adjusted to a proper position, and then the limit card block 44 on its side is snapped into the limit card slot 42 at the corresponding position. When the limit card block 44 moves to the bottom end of the limit card slot 42, the first installation slot 43 and the second installation slot 45 are in a through corresponding state. Then, the limit pin 46 is passed through the first installation slot 43 and the second installation slot 45 at one time, and then the threaded cap 48 is screwed onto the outside of the threaded column 47 in sequence to complete the overall installation of the fence frame 1. The disassembly is the same.

[0024] The limit card block 44 is set in an inverted "L" shape; Here, the limit card block 44 is set in an inverted "L" shape, the upper end of which is convenient for supporting the fence frame 1, and the lower end is convenient for snap-fit installation.

[0025] The adjustment support mechanism 5 includes a limit block 51 and a limit post 52. The limit block 51 is slidably installed inside the adjustment box 3. The outer wall of the bottom end of the limit block 51 is provided with a limit post 52. The extending end of the limit post 52 is located below the adjustment box 3. A first threaded groove 53 is formed through the outer wall of the side of the limit post 52. The side outer wall of the adjustment box 3 is provided with a second threaded groove 54 at equal intervals. The first threaded groove 53 and the second threaded groove 54 are threadedly installed with a positioning bolt 55. When it is necessary to adjust the support height of a single support foot of the device according to the terrain height difference at the installation position, first, the positioning bolt 55 needs to be screwed out from the inside of the second threaded groove 54. Then, the limit post 52 changes from the locked state to the movable state. Subsequently, directly pull the bottom end of the limit post 52 to adjust it to the appropriate support height. When the limit post 52 moves, it will automatically drive the limit block 51 to slide inside the adjustment box 3 and play a role in limiting and supporting the movement of the limit post 52.
