Abstract
A trimmer includes a handle assembly, a power mechanism installed at one end of the handle assembly, and a blade assembly connected to the power mechanism. The power mechanism has a housing assembly, a motor received in the housing assembly, and a power transmission assembly mounted on the housing assembly. The motor is an external rotor motor with a diameter greater than or equal to 50 mm. The power transmission assembly has pinion coaxially sleeved on an output shaft of the motor and a big gear meshing with the small gear, and a transmission ratio of the small gear to the big gear is less than 6. By such arrangement, the trimmer can obtain the best output effect under a condition that the output power of the motor is unchanged.
