The present invention relates to a novel pipe tool device. The device comprises a drill attachment which can be secured to any type of standard impact or drill gun capable of tightening or loosening PVC and threaded pipes of varying sizes. The drill attachment comprises a gap ring and a slip die which allows the drill attachment to tighten or loosen piping. The drill attachment can be connected to any standard drill bit attachment and activated in a clockwise or counterclockwise direction for tightening or loosening applications. The pipe tool device rotates open and closed and includes a support beam on the drill. Further, a second drill attachment can be provided, which functions as a pipe cutter.

The present invention relates to the technical field of hand-held tools. Disclosed is a hand-held power tool, comprising: a housing; a motor; a chuck assembly; and a transmission mechanism having a drive shaft. The chuck assembly comprises a main body, a jaw, and an adjustment member threadedly connected to the jaw. The power tool has a drilling mode in which the main body, the jaw and the adjustment member rotate together, and an auto chuck mode in which the adjustment member and the main body can rotate relative to each other to realize opening and closing of the jaw. The power tool further comprises a first supporting member and a second supporting member used to rotatably support the main body at the housing. The first supporting member and the second supporting member are at least partially overlapped with the jaw in an axial direction of the drive shaft, such that the power tool is structurally compact in the axial direction. The main body is provided with an accommodation cavity therein. The first supporting member is positioned in the accommodation cavity, such that the tool is also structurally compact in a radial direction.

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 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 motor starting assembly for starting a pull start motor includes a cup that is attachable to a flywheel of a pull start motor. A cylinder is insertable into the cup and the cylinder engages the cup when the cylinder is rotated in a first direction. In this way the cylinder can rotate the crankshaft of the pull start motor for starting the pull start motor. The cylinder disengages the cup when the when the rotational speed of the cup exceeds the rotational speed of the cylinder. In this way the cylinder facilitate the pull start motor to run without rotating the cylinder. An adapter is releasably attachable to the cylinder and a power drill thereby facilitating the power drill to rotate the cylinder when the power drill is turned on for starting the pull start motor.

The invention relates to a collet chuck (1) for clamping a preferably cylindrical tool shank with a chuck body (2) of a collet (3) and an union nut (4), which are matched in such a way that the collet (3) can be driven into the chuck body (2) by tightening the union nut (4) such that it secures the tool shank in the collet chuck (1) ready for operation, wherein the collet (3) and the union nut (4) are permanently connected to one another and at the same time connected in a rotatable manner relative to one another.

A chuck including a chuck body that supports a plurality of jaws. An outer sleeve is axially fixed with respect to the chuck body. A nut is coupled to the outer sleeve, and the nut is movable axially and radially relative to the chuck body. The nut interacts with the jaws such that when the outer sleeve rotates, the nut moves axially and radially relative to the body.

Electronic spindle lock for a power tool. One embodiment provides a power tool including a housing, a bit receiving portion provided on the housing for receiving a power tool bit, a motor within the housing configured to rotate the bit receiving portion, and a controller coupled to the motor. The controller is configured to enter an electronic spindle lock mode, and detect rotation of the bit receiving portion in a first direction. The controller is also configured to control motor to rotate in a second direction in response to detecting rotation of the bit receiving portion in the first direction.
