A riding lawn mower (100) includes a seat (15) for a user to sit thereon, a chassis (16) configured to support the seat (15), a cutting assembly (11) mounted to the chassis (16), a walking assembly (12) configured to drive the riding lawn mower (100) to walk on a plane, and a steering wheel assembly (136) including a steering wheel (1362) operable by the user and a connecting rod (1361) configured to connect the steering wheel (1362) and the chassis (16). The steering wheel assembly (136) further includes a pivot assembly (1368) that connects the connecting rod (1361) and the chassis (16). The pivot assembly (136) enables the steering wheel assembly (136) to switch between a working position and a storage position. A distance between the steering wheel (1362) and the plane when the steering wheel assembly (136) is in the storage position is smaller than a distance between the steering wheel (1362) and the plane when the steering wheel assembly (136) is in the working position. The steering wheel assembly (136) makes a smaller packing dimension during transportation and storage of the riding lawn mower (100). A display interface of a power tool and a riding machine are provided.
A01D 34/64 - Mowers; Mowing apparatus of harvesters characterised by features relating to the type of cutting apparatus having rotating cutters having cutters rotating about a vertical axis mounted on a vehicle, e.g. a tractor, or drawn by an animal or a vehicle
A power tool includes a housing, a drive motor, an energy source interface, a first switch, a second switch, and a control unit. The energy source interface is used for access to an energy source to provide a power supply for the drive motor. The first switch is disposed on a power supply circuit of the power supply and is capable of controlling the drive motor to rotate in a full power output mode. The second switch is disposed on a power supply circuit of the power supply and is capable of controlling the drive motor to rotate in a variable power mode. The control unit is capable of controlling the drive motor to rotate in the full power output mode when the first switch is turned on and of controlling the drive motor to rotate in a variable power output mode when the second switch is turned on.
A sanding tool includes a baseplate assembly, a housing assembly, a drive mechanism, and a fan assembly. The baseplate assembly includes a baseplate. The housing assembly includes a body housing. The housing assembly further includes a functional housing, where a hollow cavity is formed in the functional housing, the functional housing is provided with an inlet and an outlet that communicate with the hollow cavity, the inlet communicates with a dust removal channel of the sanding tool, the outlet is configured to discharge gas in the cavity, and the fan assembly is used for forming a dust removal air path moving towards the inlet. A ratio of an area of a projection of the functional housing on the baseplate to an area of the baseplate is greater than or equal to 0.15 and less than or equal to 0.95.

A table saw includes a workbench, a support frame, a cutting assembly, a mounting device, and a first lighting mechanism. The workbench has a workplane. The support frame is used for supporting the workbench. The cutting assembly includes a cutting element, where the cutting element is disposed at least partially above the workplane, and a drive device that drives the cutting element to rotate around a rotational axis in a cutting plane. The mounting device is disposed above the cutting element. The first lighting mechanism is disposed on the mounting device and generates a first lighting region toward the cutting assembly.
