A lawnmower

PendingCN122498349ANot easy to polluteEnsure linear motion stability
The application discloses a mower, and belongs to the technical field of agricultural machinery, garden machinery or engineering machinery, which comprises a deflection base frame, a connecting rod mechanism and a spring; a first hinging point is arranged on a main support; a second hinging point is arranged on one side of the deflection base frame; a third hinging point is arranged on the other side of the deflection base frame; the deflection base frame is rotationally connected to the main support through the third hinging point; the spring is installed on the connecting rod mechanism and is used for driving the connecting rod mechanism to reset after the connecting rod mechanism is compressed due to external force acting on the mower head; the passive avoidance and automatic reset of the mower head are realized through cooperation of the deflection base frame, the connecting rod mechanism and the spring, and the structure is compact and responds rapidly. The pure mechanical structure does not need sensors and active control, has low cost, high reliability, and an avoidance stroke is not limited, so that the mower head and the driving mechanism can be effectively protected.
