Cowshed fence

The utility model provides a cowshed fence which comprises at least three vertically-arranged supporting columns, all the supporting columns are distributed in a polygonal mode at intervals, a side guardrail is correspondingly arranged between every two adjacent supporting columns, one side guardrail comprises a plurality of transverse rod assemblies which are sequentially arranged in a stacked mode in the height direction of the supporting columns, and the transverse rod assemblies are connected with the supporting columns. Each cross rod assembly is composed of two lifting mechanisms, two connecting bases and a cross rod, wherein the two lifting mechanisms are mutually symmetrical and spaced, the two connecting bases are installed at the transmission ends of the lifting mechanisms in a one-to-one correspondence mode and driven by the corresponding lifting mechanisms to do lifting motion, and the cross rod is arranged between the two connecting bases in a connected mode. The two lifting mechanisms of each tr
