An electric lawn mower includes: a body (1); a cutting element (2) disposed on the body (1) and a driving assembly (6) driving the cutting element; a battery pack accommodating cavity (51) provided with conductive electrode sheets (53) for insertion of at least two battery packs (7); a shielding mechanism (52) provided in the battery pack accommodating cavity (51) and being movable relative to the conductive electrode sheet (53), where the shielding mechanism (52) has a protection state of shielding the conductive electrode sheet and a working state of releasing shielding of the conductive electrode sheet to expose the conductive electrode sheet; and an elastic member (9) disposed between an inner wall of the battery pack accommodating cavity and the shielding mechanism and configured to apply a restoring force to the shielding mechanism (52), to provide the shielding mechanism with a tendency of moving toward the protection state or maintaining the protection state. The electric lawn mower can avoid an electric shock accident caused by accidental touch of the conductive electrode sheet, and has good safety performance An electric wheeled vehicle, a battery device, and an electric tool are also provided.
