<p>Disclosed is a novel drill chuck, provided with a front body (1), a rear body (9), a front socket (10), a rear socket (40), clamping jaws (6), wherein the clamping jaws (6) are provided with clamping jaw external threads (22), gears (4) are provided between the clamping jaws (6) and the rear socket (40), the rear socket (40) is connected to the gears (4), internal threads (23) are internally provided in the gears (4), and the internal threads (23) of the gears (4) and the external threads (22) of the clamping jaws (6) are matched to each other. By means of the novel drill chuck, the problems of insufficient clamping force in the prior art drill chucks, inconveniently opening the drill chuck due to too large clamping force, and small applicable range can be solved, so that the novel drill chuck can be widely applied to the field of machining.</p> |
