ABSTRACT:
A quickly collapsible protective cover unit for a table sawing machine includes two protective covers, two connecting rods, an elongate base and a dividing plate. The dividing plate has its upper end combined between two lengthwise sides of one end portion of the base, provided with plural slots for a fitting rod of plural fixing blocks located at one end portion of the base to fit therein. The slots respectively have a stop edge for retaining the fitting rod therein, not to loosen out of the slots when the fitting rods are pushed in the slots. Then the compress bolt and the fitting rods can tightly force the base and the dividing plate combined with each other. So the protective cover unit can be assembled or collapsed quickly, without using any tool, by handling the compress bolt.
