A power tool includes a housing, a motor, a power output member, a transmission assembly, and a light source device. The power output member extends substantially along an axis and is connected to an operating accessory, and the operating accessory is provided with a working portion. The light source device includes a light guide plate, a light-emitting element, and a circuit board. The light guide plate is formed with a light exit surface for emitting light and a first light incident surface and a second light incident surface for guiding light into the light guide plate. The circuit board is used for installing the light-emitting element. A maximum distance L between the first light incident surface and the second light incident surface along a left-and-right direction is greater than or equal to 0 mm and less than or equal to 7 mm.

A power tool includes: a motor; an output part configured to be rotated around a rotational axis in response to energization of the motor; a plurality of lights disposed spaced apart around the output part; and an optical member having a refractive surface that refracts, radially outward of (away from) the rotational axis, illumination light emitted from a light-emitting surface of one of the lights.

A multipurpose and universal wrench for tightening and loosening a fastener, such as a lug nut. The wrench or lug nut wrench can be adapted to lug nuts of varied sizes and shapes. The wrench includes four arms arranged in a cross shape, and three arms are functional while the fourth arm has a torque adjusting handle. Sockets can be interchangeably coupled to the three functional arms. Moreover, the arms are telescoping allowing changing the effective length of the arms. The two opposite functional arms can pivot for collapsing the wrench for storage.

A power tool includes a housing containing a motor, an output member configured to be driven by the motor to perform an operation on a workpiece, and a handle having a first end portion coupled to the housing and a second end portion. A base is coupled to the second end portion of the handle. A light emitting assembly is pivotably coupled to the base. The light emitting assembly is configured to be operable in a first mode to illuminate a workpiece and a second mode to indicate a condition of the power tool responsive to the power tool signaling the condition to the light emitting assembly.
