    Abstract: The drill chuck includes an input shaft having a cavity, a chuck actuating shaft and a chuck actuating screw. The chuck actuating shaft is received in the cavity and is rotatable about a chuck axis. The chuck actuating shaft has a threaded aperture. The chuck actuating screw has a threaded portion threadably engaged to the aperture. The jaws are received in the cavity and engage the input shaft. Rotation of the chuck actuating shaft relative to the chuck actuating screw translates the jaws so that the jaws converge toward or diverge from the chuck axis. The chuck further includes a device coupled to at least one of the chuck actuating screw, the chuck actuating shaft and the input shaft for limiting elastic elongation of the chuck actuating screw in an axial direction when the jaws are fully opened.

    Abstract: The present invention relates to a power drill chuck which includes a drill body, a nut, jaws, a front sleeve, a rear sleeve, a nut sleeve, a rolling body. Said three jaws are mounted in three inclined holes which are trisection of said drill body. The nut thread constitutes the thread drive together with the thread of said jaws mounted in said inclined holes of said drill body. Said front sleeve is connected with said drill body, and said nut sleeve fixed by connection with said nut extends backwards, whose rear end portion a plurality of projecting keys are provided in. Said rear sleeve is mounted around the rear of said nut sleeve and may rotate relative to said nut sleeve and drill body. There provided some piecewise annular holes in rear end face of said rear sleeve and a plurality of keys on the inner end face. A positioning sleeve fixed by connection with the rear portion of said drill body may position axially the said rear sleeve on the drill body. A plurality of elastic impact members are mounted between said nut sleeve and rear sleeve. Said elastic impact members are provided with a plurality of elastic deformation portions and a plurality of projecting keys. A location ring in accordance with the present invention is provided in the rear sleeve and rear portion of said drill body. There are some connection keys and connection holes on the location ring. According to the present invention, the art scheme is suitable for all kinds of clamping of drilling tool which has a powered clamping function, so as to improve the gripping power for handle of the tool.

    Abstract: A tool driver includes a housing (30) and a rotatable drive shaft (28). A chuck (10) for holding the tool includes a generally cylindrical body (12) having a nose section (80) and a tail section (82). Jaws (16) are slidably positioned in angularly disposed passageways (42) in the body (12). Each jaw (16) has a jaw face (34) and threads (36) formed thereon. A nut (18) is in operative communication with the drive shaft (28) so that the drive shaft (28) rotationally drives the nut (18). The nut (18) engages the jaw threads (36) so that rotation of the nut (18) moves the jaws (16) axially within the passageways (42). A locking mechanism (20, 48) is mounted to at least one of the housing (30) and the body (12) and is selectively actuatable to first and second operative positions. In the first position, the locking mechanism (20, 48) rotationally locks the housing (30) and the body (12) with respect to each other. In the second, it permits relative rotation between the body (12) and the housing (30).
