The robotic tool includes a body (), an upper cover () and a connecting device (). The connecting device () includes a connecting seat fixed on the upper cover and a connecting rod () fixed on the body. The connecting seat includes a locking component (), and the locking component is provided with a plurality of elastic connecting walls (), and the elastic connecting walls () jointly define a sunken cavity () to house a connecting head of the connecting rod. When the locking component () is in a release position, the elastic connecting walls can be deformed outward to allow the connecting head to be removed from the sunken cavity. When the locking component is in a locking position, the elastic connecting walls are restricted from deforming outwards to keep the connecting head in the sunken cavity ().

The invention provides a mower. The mower comprises a housing and a cutting device arranged in the housing. The mower is provided with a height adjustment device. The height adjustment device comprises a rotating member and a traction member arranged on the housing. One end of the traction member is fixed on the rotating member, and the other end of the traction member is fixed on the cutting device. The rotating member rotates to drive the traction member to adjust the height of the cutting device. Such an arrangement makes the mower have a simple structure, save internal space of the mower, and be convenient to operate.

A ring-shaped cushion for a hearing protector or audio headset. The cushion has a circumferential contact pad for sealing on a wearer's head and an attachment for sealing with an earmuff. The cushion further has a sound insulation tube that inwardly defines an inner space. The sound insulation tube extends between the contact pad and the attachment. The cushion has a ventilation passage that extends entirely through the cushion between an inlet opening in the contact pad and an area outside of the inner space. The cushion may further include one or more physiological sensors to monitor the health of a wearer.
