A drill chuck having a chuck body, which is produced from plastic, in particular from fiber-reinforced plastic, and has a spindle holder and a tool holder and in which clamping jaws that can be adjusted by a threaded ring are guided. The chuck body has a securing ring on an outer circumference in a region of the tool holder.

The invention relates to a power drill, having a tool-clamping device that is fastened to a spindle shaft, having a torque clutch that includes an axially movable clutch plate on which an axial force is exerted by a plurality of compression springs that cooperate at least indirectly with an adjusting nut situated on a housing component. The compression springs are accommodated in first recesses embodied in the longitudinal direction of the housing component. A device for axially moving an axial bearing situated on the spindle shaft, is provided at the end of the spindle shaft oriented toward the tool-clamping device. According to the invention, on its side oriented toward the clutch plate, the device for axially moving the axial bearing has at least one actuating section that is situated in a second recess of the housing component and on the side oriented toward the clutch plate, cooperates with an adjusting element for the device.

A chuck (10) has a body (14), a plurality of jaws (22), and a rotatable nut (16). A sleeve (18) is rotatable between a first rotational position and a second rotational position with respect to the nut. An annular array of first teeth (84) are non-rotatable with respect to the body. One or more second teeth (63) are non-rotatable with respect to the nut and axially movable with respect to the body. When the teeth engage, they resist the nut's rotation in the opening direction. An engagement between the sleeve and the one or more second teeth moves the one or more second teeth out of engagement with the first teeth when the sleeve moves from the second rotational position to the first rotational position and moves the one or more second teeth into engagement with the first teeth when the sleeve moves from the first rotational position to the second rotational position.

A chuck configured to be operably coupled to a power driver having a rotatable drive spindle is provided. The chuck (100) may include a body (130) having a center axis (50) and a plurality of clamping jaws (101) configured to clamp onto a working bit. The clamping jaws (101) may be configured to angularly translate relative to the center axis towards or away from a clamping jaw point of convergence (154) to close or open a working bit opening defined by the clamping jaws (101). The clamping jaw point of convergence (154) may be on the center axis. The chuck (100) may also include a plurality of bit alignment jaws (150). The bit alignment jaws (150) may be configured to maintain the working bit within the working bit opening by being configured translate towards or away from a bit alignment jaw point of convergence (153) that is on the center axis (50) and disposed rearward of the clamping jaw point of convergence (154).

Some embodiments of the present disclosure provide a drill chuck. The drill chuck includes: a drill body; jaws, partially disposed in the drill body, external threads being provided on an outer wall of the jaws; a locking member, disposed on the outer side of the drill body, the locking member being provided with internal threads, the locking member and the jaws being in threaded fit to enable the jaws to be movably disposed in the drill body; a driving assembly, disposed on an outer side of the locking member, the driving assembly being configured to drive the locking member to rotate, the driving assembly being disposed between a housing and the locking member, the housing driving the locking member to rotate by the driving assembly to enable the jaws to move in the drill body; and a locking structure, located between the housing and the jaws.

A chuck is provided for use with a powered driver having a rotatable drive shaft. The chuck includes a plurality of jaws movably disposed in passageways of a cylindrical body, a nut rotatably mounted about the body and in communication with the jaws such that rotation of the nut in a closing direction moves the jaws toward each other and rotation of the nut in an opening direction moves the jaws away from each other, and a sleeve rotatably mounted about the body. The sleeve is in communication with the nut such that rotation of the sleeve rotationally drives the nut. The chuck also including a biasing element disposed between the nut an at least a portion of the sleeve configured to bias the sleeve toward a neutral position. The biasing element limits an inertial force of the sleeve applied to the nut during operation of the powered driver.

Provided is a chuck apparatus enabling ease of rotation of a rotating cylinder in the loosening direction when replacing a tool, suppressed wear of the ratchet teeth, and a longer life span. Through the rotation of a rotating cylinder (1), the chuck apparatus expands or contracts a plurality of jaws (3) inserted into a hole (2a) provided to a tip end of a body (2), and sandwiches and holds a tool (4) using the jaws (3). An annular rotating body (8) screwed together with the jaws (3) and rotating together with the rotating cylinder (1) is fitted to the body (2) inside the rotating cylinder (1). Annular ratchet teeth (5) are provided to the body (2) or the rotating body (8), a detachable locking spring body (9) for locking with the ratchet teeth (5) is provided, and a lock release mechanism is provided for forcibly releasing the locking between the ratchet teeth (5) and the locking spring body (9) when a rotational force in a tightening direction is brought to zero after the rotating cylinder (1) has been rotated in the tightening direction and a holding force on the tool (4) has reached a predetermined value.

A chuck for use with a power driver having a rotatable drive spindle is provided. The chuck may comprise a plurality of jaws, a front body, a nut, a rear body, and a clutch. The clutch may be configured to move between a working position and a jaw actuating position. In the working position, the clutch teeth may be engaged with the rear body teeth such that rotation of the rear body by the drive spindle rotates the clutch, the front body, and the jaws. In the jaw actuating position, the clutch teeth may not or need not be engaged with the rear body teeth and the rear body may be configured to rotate the nut relative to the front body to move the jaws relative to the front body.

A chuck (10) is provided that includes a plurality of jaws (20) and a body (30) configured to rotate with a drive spindle of a power driver. The chuck (10) may also include a nut (80) comprising nut teeth (82). The nut (80) may be operably coupled to the jaws (20) and configured to move the jaws (20) relative to the body (30) in the opening or closing direction. The chuck (10) may also include a clutch (100) comprising clutch teeth (102). The clutch (100) may be configured to move between a working position and a jaw actuating position. In the working position, the clutch teeth (102) may be engaged with the nut teeth (82) to prevent movement of the nut (80) relative to the body (30), and, in the jaw actuating position, the clutch teeth (102) need not be engaged with the nut teeth (82) and the nut (80) may be free to move relative to the body (30).

A tool bit connectable to a tool. The tool bit including a tool body having a working end portion, an insertion end portion, and an outer surface formed on the insertion end portion. The insertion end portion defines an end of the tool body and configured to be coupled to the tool. The tool bit also includes a non-circular profile formed on the tool body and partially defining the outer surface, and an alignment region positioned between the non-circular profile and the end of the tool body. The alignment region partially defines the outer surface to facilitate alignment of the non-circular profile with the tool.
