The invention relates to a hand-held electric tool which comprises a motor and an operation device. The operation device is operated by a user and comprises a handle shell forming an operation handle held by the user, a master control switch used for controlling on and off of a power source of the motor, a speed regulating switch used for controlling the rotating speed of the motor, a master control operation piece used by the user for operating the master control switch and a speed regulating operation piece used by the user for operating the speed regulating switch; the operation handle is provided with a middle dividing face and is symmetrically arranged with respect to the middle dividing face; and the speed regulating operation piece is arranged on one side of the middle dividing face. According to the hand-held electric tool, the setting of the operation devices meets the human engineering, and operation is comfortable, convenient and rapid.
Description
technical field [0001] The invention relates to a hand-held electric tool. Background technique [0002] Hand-held power tools include working devices and power devices. The power unit provides power for the working device. When the power device uses electricity as the energy source, such hand-held power tools can also be called hand-held power tools. Common handheld power tools include: pruners, lawn trimmers, pole saws, etc. [0003] Hand-held power tools include an operating device. The operating device is equipped with a trigger for controlling the start of the machine and an operating part for controlling the speed. The traditional operating part for controlling the speed is arranged directly above the handle, and its layout is unreasonable, so it is difficult for the user to control the trigger. while controlling the speed. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the object of the present invention is to provide an ...
