An operating system for doors/windows (10) with multiple locking points comprising a gear casing (20) through which a drive bar (40), an exposed hinged corner device (50) and an opening mechanism (60) are controlled by a handle (30), so as to tilt and/or inward open the door/window (10). The gear casing (20) includes a first and a second casings (21, 22) made from plastic, wherein the first casing (21) has at least one insertion hole (211) while the second casing (22) has a corresponding bored connecting rod (221) comprising a plurality of grooves (222) defining tightening pieces (223), thereby when the first and second casings (21, 22) are connected, the bored connecting rod (221) is inserted into the insertion hole (211) and a positioning pin (25) is passed through the insertion hole (211) and the bore connecting rod (221), so that the positioning pin (25) presses the tightening piece (223) to expand outward so as to make the bore connecting rod (221) fit in the insertion hole (211) tightly . |
