The hollow tubular sleeve has two symmetrical elongated wings where the pinholes existed respectively. The socket sleeve is the same as the hollow tubular sleeve having two symmetrical elongated wings where pinholes are on the same line with the central bore located on the top of the socket sleeve. There are slots formed between the socket sleeve and its two symmetrical elongated wings for receiving two symmetrical elongated wings of the hollow tubular sleeve. By using a rivet to pivotally connect the hollow tubular sleeve coupled on the lengthwise rib with the socket sleeve set on the top of the transverse rib together, thus linking the lengthwise rib and transverse rib collectively and that greatly enhancing the connecting strength of the pivoted part thereof.
