Strength-boosting drill chuck

A strength-boosting drill chuck comprising a drill body, a nut and a clamping claw, the drill body being provided with an inclined clamping claw hole for the clamping claw to slide forward and backward along the clamping claw hole;

• wherein the drill chuck is provided with a strength-boosting structure for connecting the nut and the clamping claw, the strength-boosting structure is provided with a liquid plastic component, and a structure for exerting and transmitting force to the liquid plastic component, so that the force on the liquid plastic component can be transmitted to the nut, and
• the drill chuck is provided with a clutch connection structure, and the structure for exerting and transmitting force to the liquid plastic component is provided with a structure for exerting force to the liquid plastic component the clutch connection structure is connected to the nut but not to the strength-boosting structure when the drill chuck is not in a clamping state, and the clutch connection structure is connected with the structure for exerting force to the liquid plastic component without being connected to the nut after the drill chuck is changed from the unclamping state into the clamping state;
• the clutch connection structure is provided with a portion that receives external force and can be driven to rotate by the external force, and by rotation, the drill chuck drives the nut to rotate when the drill chuck is not in clamping state;
• when the drill chuck is in the clamping state, the continuous rotation in the same direction drives a structural movement that exerts force to the liquid plastic component, and the force is transmitted to the liquid plastic component.
