  • Publication number: 20230240181
    Abstract: A garden tool includes a cutting assembly, a first driving device and a height adjustment assembly. The first driving assembly includes a prime mover fixedly mounted on a tool body and a transmission mechanism that transmits power output by the prime mover to the cutting assembly. The transmission mechanism is used to transmit the power output by the prime mover to the cutting assembly to drive the cutting assembly to work. The height adjustment assembly is used to drive the cutting assembly to move in a direction perpendicular to a working plane, so as to adjust a distance of the cutting assembly from the ground. The garden tool of the disclosure directly adjusts a height of a mower from the ground through the height adjustment assembly without adjusting a position of a heavy motor.

  • Patent number: 11062861
    Abstract: Safety switch for a gardening device driven by a motor. The safety switch includes a main button arrangement and a sub button arrangement which is provided onto the main button arrangement. The main button arrangement may pivot between a first position and a second position. In the first position the sub button arrangement may be provided in an arrest position and in the second position the sub button arrangement is arranged in an energize position. Further, the sub button arrangement includes biasing means by means of which biasing means the sub button arrangement is biased towards the arrest position in the first position, and by application of an external force the sub button arrangement may be moved towards a biasing force exerted by the biasing means and be slid to the energize position where the main button arrangement may activate the power means in the second position.
