A dust collector includes a post extended from a base, a housing disposed on the post, a dust collecting receptacle, a cover coupled to the housing and disposed above the dust collecting receptacle for selectively closing the dust collecting receptacle or for selectively opening the dust collecting receptacle, and an actuating device for selectively actuating the cover to close the dust collecting receptacle, and for selectively moving the cover away from the dust collecting receptacle to open the dust collecting receptacle and to allow the dust collecting receptacle to be moved either away from or toward the base and to allow the dust to be easily dumped or removed from the dust collecting receptacle.
