    Abstract: A trimmer head includes a spool formed with a winding portion for winding a trimmer line and a head housing formed with an accommodating space for accommodating at least a portion of the spool. The trimmer head further includes an intermediate element for transmitting a torque between the spool and the head housing such that one of the spool and the head housing rotates with the other. The spool drives the intermediate element to rotate and the intermediate element is slidably connected to the spool in a direction along a rotation axis or parallel to the rotation axis. The spool does not move in the axial direction when the trimmer head of the grass trimmer is unwinding the trimmer line, thereby effectively avoiding the problem of the trimmer line jamming.

    Abstract: A mower includes an electric motor, a main machine body, an electronic component, and an operating assembly. The main machine body extends in a forward-backward direction. The operating assembly includes a handle assembly and a first operating member. The handle assembly is rotatably connected to the main machine body and configured to be held to operate the mower to run. The first operating member is rotatably connected to the handle assembly to control a walking state of the mower. The first operating member is formed with a fitting surface fitting with the handle assembly. In response to the first operating member being operated to rotate and approach the handle assembly, the fitting surface is capable of substantially fitting flush with the handle assembly to form a unitary component that is capable of being held.

    IPC: B62B5/06

    Abstract: A hand-propelled power tool includes a main body, a handle assembly, a fixing plate assembly, and a walking assembly connected to the main body. The handle assembly includes a first connecting rod and a second connecting rod. The first connecting rod is provided with a first adjusting assembly. The second connecting rod is provided with a second adjusting assembly. The first adjusting assembly and the second adjusting assembly form a linkage by a connecting member. The first adjusting assembly and the second adjusting assembly include a first movement state and a second movement state. When in the first movement state, the connecting member can transmit a force between the first adjusting assembly and the second adjusting assembly. When in the second movement state, the connecting member does not transmit a force between the first adjusting assembly and the second adjusting assembly.
