This technical solution enables the trapezoidal support portion to provide corresponding supporting force for the wire mesh on the connecting ring, thereby improving the structural stability of the connecting piece.

[0029] Working principle: The present application assembles two basic poles to form a column module, and uses a single basic pole directly placed horizontally to form a bottom pole module. This embodiment can set the length of the column module and the bottom pole module by setting the number of basic poles according to actual needs, assemble by selecting the length of the appropriate diagonal brace rod, and then connect the wire mesh to each other through the connecting ring to complete the installation of the anti-fall net. In order to improve the stability of the anti-fall net, one side of the diagonal brace rod can be placed outward during actual installation.
