A container includes a base including base walls and a cavity defined by the base walls, a lid movably coupled to the base to selectively enclose the cavity, a first engagement member coupled to one of the base walls, and a hinge rotatably coupled to the base and to the lid adjacent the one of the base walls. The hinge includes a second engagement member that selectively engages the first engagement member. The hinge is held stationary relative the base when the first engagement member engages the second engagement member, and the hinge is movable relative the base when the first engagement member disengages the second engagement member.

A knockout tool for forming a hole in a material, such as a sheet of metal, is provided. The knockout tool includes a body, a die mounted on a first end of the body, and a punch mounted on the second end of the body. A die plug is coupled to the first end of the body by a drive component, and a thrust bearing is positioned between the die and die plug such that at least a portion of the thrust bearing can rotate between the die and die plug. When the drive component is rotated in a first direction, the die plug and thrust bearing convert rotational movement of the drive component into linear movement and move the die into engagement with the punch.

A hand tool includes a first jaw, a first handle fixed to the first jaw, a second jaw, and a second handle pivotally coupled to the second jaw, a link member, and an adjustment member. The adjustment member is operable to axially move a first end of the link member to vary a distance between the first and second jaws. The adjustment member includes an engagement surface engageable with the first end of the link member, a shank in threaded engagement with a bore in the first handle, and a flange extending from the shank opposite the engagement portion. The flange includes a first side, a second side opposite the first side, and an elongate opening extending through the first and second sides.

Abrégé

A power tool and methods are provided for detecting objects (e.g., flesh or other materials) in the operating path of a power tool's output component (e.g., saw blade or drill bit). An object detection sensor in the power tool generates an output signal indicative of a type of material detected in the operating path of the power tool. A power tool controller receives the object detection sensor output and determines when a material in the operating path of the power tool changes. The controller changes operation of a motor of the power tool (e.g., increasing or decreasing speed or stopping the motor) in response to the detected material change. The object detection sensor may include, for example, an RF sensor, a capacitive sensor, a camera, a conductivity probe, or an ultrasound probe.

Power tools that include a housing, a motor supported by the housing, an inverter positioned between and electrically connected to a battery pack interface and the motor, a gate driver connected to the inverter, a rotational position detector configured to detect a position of the motor, a controller configured to control the gate driver, and a short circuit detection circuit. The short circuit detection circuit is configured to monitor the current in the inverter, compare the current in the inverter to a first current threshold, determine, in response to the current in the inverter being greater than or equal to the first current threshold, whether the position of the motor is changing based on a signal from the rotational position detector, and control, in response to the position of the motor not changing, a switch of the short circuit detection circuit to disable the gate driver.

A battery-pack-powered device includes an interface configured to receive a battery pack, a sensing circuit configured to detect a voltage of the battery pack, and an electronic controller. The electronic controller is configured to receive a first signal from the sensing circuit indicative of a no-load voltage of the battery pack, determine a threshold voltage based on the no-load voltage, generate a control signal to drive an electric motor at a first operating parameter in response to an activation of a trigger switch, receive a second signal from the sensing circuit, and update the control signal to drive the electric motor at a second operating parameter less than the first operating parameter in response to the second signal indicating that the output voltage is below the threshold voltage. The second signal is indicative of an output voltage of the battery pack during operation of the electric motor.
