Abstract
The utility model provides a hand-tightening drill chuck, which comprises a drill body, a nut, a gripping jaw in threaded connection with the nut, a rear sleeve and a rotary sleeve driving the nut to rotate. The rotary sleeve can slide in the axial direction of the drill chuck; the drill chuck is provided with a sleeve body which is connected with the nut; the sleeve body is provided with a guiding element for allowing the rotary sleeve to axially slide; the inner wall of the rotary sleeve is provided with a guiding-fitting piece which is matched with the guiding element; and the drill chuck is provided with a positioning mechanism for the rotary sleeve after sliding backwards to be reset as well. When a user operates the drill chuck to clamp or loosen a bit, the rotary sleeve can be pulled forward with a distance, thereby ensuring that the hands of the user can fully grasp the rear sleeve and the rotary sleeve of the drill chuck so as to conveniently operate the drill chuck, and after operation is completed, the rotary sleeve can slide backwards to be reset, so as to maintain the prior shape of the drill chuck.
