摘要

A position-fixing sleeve for an electric drill dust cover, comprising: a sheathing part (31); a fixing part (21) positioned at the front of the body of an electric drill (20); a supporting part (32) extending from the sheathing part toward the drill bit (22) of the electric drill and wrapping and isolating a rotating part (23) of the electric drill; a dust cover (40) combining and fixing the position thereof on the supporting part; a connecting ring (322) disposed on the outside of the supporting part, the inside of the connecting ring forming a dust collecting groove (321) that communicates with the inside of the dust cover. The position-fixing sleeve for an electric drill dust cover substantially enhances the dust-proof effect of the dust cover and user safety.
