摘要： An electric weeder includes a body and a working head. The body includes a drive mechanism. The drive mechanism includes a motor for driving the working head to rotate around a first axis. The drive mechanism has a first working mode in which the working head is screwed into a workplane and a second working mode in which the working head is unscrewed from the workplane. The direction of rotation of the working head in the first working mode is different from the direction of rotation of the working head in the second working mode. The output rotational speed of the working head is less than or equal to 400 RPM in the first working mode.

摘要： A standing light includes a light assembly, a support rod assembly, and a housing assembly. The support rod assembly is configured to support the light assembly. The housing assembly or the support rod assembly is formed with a power access interface for being connected to a power supply. The standing light further includes a mounting assembly configured to detachably install the light assembly to the support rod assembly. When the light assembly is installed to the support rod assembly, the light assembly is capable of being powered by the power supply connected to the power access interface. The light assembly is further formed with a power supply access interface for accessing power, and when the light assembly is detached from the support rod assembly, the light assembly is capable of being detachably connected to a battery pack through the power supply access interface.

摘要： An impact tool includes a controller for controlling a motor. The controller is configured to, when the direction of rotation of the motor is set to the reverse rotation direction, a drive shaft rotates at a first speed, and after an impact mechanism applies an impact force to an output shaft for a preset time, determine that a fastener is in a tightened state according to a load parameter of the output shaft and control the drive shaft to rotate at a second speed, where the second speed is greater than the first speed.

摘要： A power tool includes a main housing, a drive mechanism, a working head, and a connection assembly. The connection assembly includes an input portion connected to the drive mechanism and an output portion connected to an output shaft. The connection assembly rotates the working head about a first axis relative to the main housing. The power tool includes a first transmission path. When the working head rotates about the first axis relative to the main housing, components in the first transmission path are allowed to deform or to be displaced along a direction of the first transmission path.

摘要： A torque output tool includes an output shaft, a motor, a transmission assembly, and a gearbox. The gearbox is used for accommodating the transmission assembly. The transmission assembly includes a first planetary gearset and a second planetary gearset. The transmission assembly is capable of being switched to a first state and a second state such that the transmission assembly outputs a first gear ratio or a second gear ratio separately, where the first gear ratio is greater than the second gear ratio. When the transmission assembly outputs the first gear ratio, a rotational speed of the output shaft is greater than or equal to 300 r/min and less than or equal to 800 r/min. A length of the gearbox in an axial direction is greater than or equal to 38 mm and less than or equal to 46 mm.
