Abstract
A grass trimmer includes a grass trimmer head, a drive device, and an operating member. The grass trimmer head includes a spool used for a grass trimmer rope to be wound around and a head housing for accommodating at least part of the spool. The drive device is configured to drive the grass trimmer head to rotate. The operating member is connected to the drive device and includes an operating portion for a user to operate. The grass trimmer has a winding mode. In the case where the grass trimmer is in the winding mode, movement of the operating member is transmitted to the spool or the head housing through the drive device so as to generate relative movement that is between the spool and the head housing and through which the grass trimmer rope is wound around the spool.
