Abstract: A dust-collecting device adaptive to a power drill comprises a container having atop a tapered portion, the tapered portion including an opening, the container having a through hole at bottom, and a positioning seat being raised around the through hole; a shaft assembly passing through the through hole, the shaft assembly having at least one bearing received in the positioning seat; a spring member being mounted around the shaft assembly; and a spacing member being coupled to one end of the spring member, the spacing member having a round hole for a bit of the power drill to pass therethrough and then pass through the shaft assembly and the opening, whereby, when the power drill drills, drill dust thus generated is guided by a taper of the tapered portion and converged in the container.
