摘要： A handheld power tool includes a motor, a handle having a first switch for starting and stopping the motor, an output assembly, and an adjustment device including a telescopic rod assembly. The length of the adjustment device changes so that the handheld power tool has at least first and second working states. The distance between the frontmost side of the handheld power tool and the rearmost side of the first switch is an effective length of the handheld power tool. When the handheld power tool is in the first working state, the handheld power tool has a first effective length T1. When the handheld power tool is in the second working state, the handheld power tool has a second effective length T2. The first effective length T1 is less than or equal to 1 m, and the second effective length T2 is greater than the first effective length T1.

摘要： A power tool includes a motor, a power terminal, a detection module, and a controller. The power terminal is configured to access a power supply of a battery pack. The detection module is capable of detecting that a first circuit between the power terminal and the battery pack is in a power-on mode or a power-off mode. The controller is capable of controlling a second circuit between the power terminal and the motor to be in a power-on mode or a power-off mode. When the detection module detects that the first circuit is switched from the power-on mode to the power-off mode, the controller controls the second circuit to be in the power-off mode within a first preset time.

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.
