[0019] Among them, a limiting structure is provided between the end ring 2 and the suspension rod 3, and the limiting structure includes a through rod 91 and a plug hole 92. The surface of the suspension rod 3 is penetrated with a through hole 31 corresponding to the through rod 91, and the surface of the end ring 2 is symmetrically provided with two plug holes 92 for the through rod 91 to be inserted. The through rod 91 is inserted into the plug hole 92, and the through rod 91 passes through the suspension rod 3 through the through hole 31, so that the end ring 2 can be stably limited, ensuring the limiting stability of the upper and lower end rings 2 on the galvanized round steel pipe 1, ensuring the installation stability of the galvanized round steel pipe 1 and the end ring 2, and both ends of the through rod 91 are opened inside An inner groove 93 is provided, in which a spring 94 and a semicircular telescopic block 95 are provided. The semicircular telescopic block 95 is movably installed in the inner groove 93 by means of the spring 94. The inner wall of the insertion hole 92 is symmetrically provided with two rectangular slots 96 corresponding to the semicircular telescopic block 95. The end of the semicircular telescopic block 95 pops out into the rectangular slot 96, so that after the through rod 91 passes through the end of the suspension rod 3, the semicircular telescopic block 95 can be inserted into the rectangular slot 96 under the push of the spring 94, thereby playing a role of clamping and limiting the through rod 91 and ensuring the installation stability of the end ring 2.

[0020] One end of the spring 94 is fixed to the inner wall of the inner groove 93 , and the other end of the spring 94 is fixed to the semicircular telescopic block 95 , thereby ensuring the installation stability of the spring 94 .
