A trimming head for use with a grass trimmer includes a spool for winding a cutting line and rotatable about an axis, a head housing formed with apertures for the cutting line to pass through, a touched element configured to be activated, a first driving member configured to drive the spool to rotate to send out the cutting line, and a first transmitting member configured to cooperate with a first driving member to receive a driving force of the first driving member. The trimming head has a sending mode in which a length of the cutting line extends without rotating the head housing.

According to examples, a machine may include a base housing and a handle assembly mounted to the base housing and extending at an angle from the base housing along a handle plane. The handle assembly may include a mating component having a plurality of slots arranged at multiple angular positions along a slot plane, the slot plane being parallel to the handle plane. The mating assembly may also include a handle segment rotatably mounted to the mating component, the handle segment housing a locking member, in which the handle segment is rotatable along the slot plane relative to the base housing and the locking member is removably insertable into a first slot of the plurality of slots when the handle segment is in a first angular position and is removably inserted into a second slot of the plurality of slots when the handle segment is in a second angular position.

An intelligent mower capable of cutting a lawn at a boundary includes a cutting mechanism, a machine body, a side part protection, and a bottom protection. The cutting mechanism is configured to execute a cutting operation, which includes cutting along the boundary as the intelligent mower automatically follows the boundary. The machine body is connected with the side part protection and the bottom protection. The side protection is located on the side of the cutting mechanism to establish a protective barrier on the side of the cutting mechanism and the bottom protection is located below the cutting mechanism to establish a protective barrier below the cutting mechanism. Additionally, the bottom protection includes a grass inlet.
