A power tool including a motor and an impact mechanism. The impact mechanism is coupled to the motor and includes a hammer driven by the motor, and an anvil positioned at a nose of the power tool, and configured to receive an impact from the hammer. The power tool also includes a sensor assembly positioned at the nose of the power tool, and an electronic processor. The sensor assembly includes an output position sensor configured to generate an output signal indicative of a position of the hammer or the anvil. The electronic processor is coupled to the output position sensor and to the motor, and is configured to operate the motor based on the output signal from the output position sensor.

A socket wrench is provided, including: a sleeving portion, including a sleeving hole disposed therethrough along a first direction; a connecting arm, extending from the sleeving portion in a direction lateral to the first direction; an operation rod; and a pin member, pinning the connecting arm and the operation rod in a direction non-perpendicular to the first direction so that the operation rod is rotatable about the pin member relative to the sleeving portion.

A clamping tool with tightening torque control includes a body containing control circuits and an electronic processing unit having at one end a handle for the grip of an operator who performs the tightening, and at the other end an arm. The arm at its free end includes a seat into which a plurality of inserts can alternatively be inserted, suitable for engaging the tool with a corresponding type and/or size of a mechanical member on which the tool is intended to act to perform a tightening operation. On the arm there is a sensor adapted to detect the tightening torque exerted on the mechanical member.

The present invention provides an extendable wrench comprising: a wrench having a head portion and a shaft connected to a rear end of the head portion; an insertion hole recessed at a rear end of the shaft; a cover to dismountably close the insertion hole; an extension rod with a front end formed with a plug to be plug-connected with or separated from the insertion hole of the wrench; and an elastic positioning member provided between the plug of the extension rod and the insertion hole of the wrench, when the plug of the extension rod is plug-connected with the insertion hole, the elastic positioning member keeps the plug in position. Thereby, the wrench can be operated independently; when application of larger operating torque is required, the extension rod can be combined with a rear end of the wrench to form a longer operating arm of force to meet the requirements of large torque.

A tool bit includes a drive portion configured to be selectively coupled to a tool. The drive portion is composed of a first material. The tool bit includes a working end portion having a shape configured to correspond with a recess of a fastener for the working end portion to engage and drive the fastener. The working end portion includes a first segment and a second segment. The first segment is located between the second segment and the drive portion. The first segment is composed of the first material. The second segment is fixed to the first segment at a connection interface. The second segment is composed of a second material different than the first material.

A dual-interface sewer cap removal device is provided. The device includes a base plate with a first side provided opposite a second side. A first interface is defined on the first side of the base plate. The first interface is designed to engage a slotted sewer cap. A second interface is defined on the second side of the base plate. The second interface is designed to engage a sewer cap. The second interface is structurally distinct from the first interface. An aperture is centrally disposed on the base plate.

A power wrench includes a cylindrical housing, an electric motor, an output shaft connected to the motor and a power switching device activated by a trigger located on the housing. The trigger is supported on an annular sleeve element coaxially disposed and rotatable relative to the housing for enabling adjustment of the angular position of the trigger relative to the housing. Irrespective of its angular position the trigger is arranged to axially displace a non-rotatable activation ring to activate the power switching device. The housing includes an adjustable angle head supporting the output shaft and arranged to be set in alternative angular positions relative to the housing.

An attaching and detaching tool for removing a flywheel connected to a crankshaft of an internal combustion engine using a nut, in which the flywheel is removed by pulling the flywheel with an axial force generated in the nut when the nut is loosened, is provided. A socket wrench is coupled to a nut connected to a crankshaft and a flywheel is coupled to a puller assembled to the socket wrench via a bolt, and then the socket wrench is rotated while the rotation of the puller is stopped by a spinner handle, whereby the nut is loosened and the flywheel is removed.

An adapter for a bearing race and seal driver tool that allows the tool to be used in hard to reach applications. The adapter connects to a driver and a handle at a non-zero angle, for example a right angle, to allow the adapter to be struck at a face of the adapter rather than the handle to be struck at an end of the handle. A pocket is included at one or more connection points between the adapter and the handle or driver to resist rotational movement of the handle or driver.

A hand tool including a control element for receiving one or more finger digits of a user. The control element is positioned on the body component and may be in the form of an aperture defined by a perimeter surface. A user places one or more fingers within the control element and applies pressure to rotate the body component.
