Wherein, the connecting rod 112 is a hollow long rod structure, and the connecting rod 112 is respectively connected with the operating part 113 and the main machine 12. The walking assembly is mounted to the main frame 12, and the power mechanism can drive the walking assembly to rotate around a rotating shaft so as to drive the whole mower 100 to move on the ground.

The handle device 11 further includes a switch box 111, the switch box 111 is provided on the operating member 113, and as shown in fig. 2 and 3, the switch box 111 includes a first cover 1111, a second cover 1112, and a third cover 1113. The first and second covers 1111 and 1112 are formed with a transverse connection portion 1114 connected to the connection rod 112. The transverse link 1114 is located between the two tie bars 112 and extends substantially perpendicular to the tie bars 112. In some embodiments, the first cover 1111 and the second cover 1112 are mounted to the connection rod 112 by screws. The third cover 1113 is configured to interface with the first cover 1111 and/or the second cover 1112. The switch box 111 defines an operation portion in which a switch device configured to control the mower 100 is arranged, and at least a part of the operation portion is formed on the third cover 1113. The handle device 11 has an operating state in which the third cover 1113 faces the user when the handle device 11 is in the operating state. The operation section is a section for the user to operate the lawnmower 100 by a key, a knob, a touch panel, a lever, or a film button. It should be noted that some handle devices 11 can be rotated and folded to facilitate the user to store the whole device, so that they have an operating state and a storage state, while some handle devices 11 can not be folded and only have an operating state.
