Abstract

A lawncare apparatus includes a main body, multiple wheels supporting the main body, a cutting blade disposed in the main body, a motor driving the cutting blade, an operating arm connected to the first end of the main body, and a transmission assembly. The transmission assembly is configured to prevent the switching device from being controlled in a mechanical way by the operation assembly or/and turning on the motor when the first member is moved towards the main body to a predetermined position relative to the second member.

First claim

What is claimed is:

1. A lawn care apparatus, comprising:
a main body;
a motor supported by the main body;
a plurality of wheels supporting the main body;
a handle connected to the main body, the handle comprising a first member and a second member wherein the first member is movable relative to the second member along a direction that is towards the main body the handle further comprising a first handle housing fixedly connected to the first member;
a switching device for controlling the motor, the switching device disposed in the first handle housing;
an operation member configured to be operated by a user, the operation member being rotatably connected to the first handle housing such that the operation member is capable of moving to a first position and a second position relative to the handle, wherein the operation member triggers the switching device to activate the motor when the operation member locates at the first position, and the switching device prevents the motor from being activated when the operation member locates at the second position; and
a safety assembly for preventing the operation member from moving to the first position when the first member is moved towards the main body to a predetermined position relative to the second member.

2. The lawn care apparatus as recited in claim 1 , wherein the switching device is disposed in the main body.

3. The lawn care apparatus as recited in claim 1 , wherein the handle further comprises a second handle housing fixedly connected to the second member.

4. The lawn care apparatus as recited in claim 3 , wherein the second member is rotatably connected to the main body.

5. The lawn care apparatus as recited in claim 1 , further comprising a second operation member for being operated by the user before using the operation member, the second operation member being movably or detachably connected to the handle, and a first clutch member for preventing the operation member from triggering the switching device when the second operation member is not operated to a preset state by the user.

6. The lawn care apparatus as recited in claim 1 , wherein the safety assembly comprises a flexible member disposed between the operation member and the switching device to transmit a drawing force between the operation member and the switching device.

7. The lawn care apparatus as recited in claim 1 , wherein the safety assembly comprises a limiting member for preventing the operation member from moving to the first position when the first member is moved towards the main body to a predetermined position relative to the second member and the limiting member is capable of moving relatively to the switching device such that the limiting member is caused to stop the operation member from being moved to the first position by the first member when the first member is moved from a predetermined position relative to the second member in a direction that is away from the main body.

8. A lawn care apparatus, comprising:
a main body;
a motor supported by the main body;
a plurality of wheels supporting the main body;
a handle connected to the main body, the handle comprising a first member and a second member wherein the first member will move relative to the second member and in a direction that is towards the main body in response to the handle being subjected to a first force that is in the direction that is towards the main body, the handle further comprising a first handle housing fixedly connected to the first member;
a switching device for turning on the motor or turning off the motor, the switching device disposed in the first handle housing;
an operation assembly for being operated by a user to control the switching device, the operation assembly rotatably connected to the first handle housing; and
a safety assembly configured to prevent the switching device from being mechanically controlled by the operation assembly when the first member is moved towards the main body to a predetermined position relative to the second member.
