Abstract

The invention relates to an electric tool control assembly. The electric tool control assembly comprises a driving component, a direct current switch, a control box and a key component, wherein the key component and the control box can be separated and connected, when the key component and the control box are connected, the key component has a first position and a second position on the control box, when the key component is located at the first position, the key component and the control box can be separated, when the key component is located at the second position, the key component and the control box can not be separated, the key component is operated so that the control box can be in an activated state, and the direct current switch can be closed by operating the driving component at the time. The electric tool control assembly adopts the key component to replace the functions of an electric key and an operation button in the prior art, and the key component can play a role in safety protection of the electric key in the prior art and can also achieve the function of the operation button in the starting process. Besides, when the key component is located at the second position, the key component can not be separated from the control box, and stable work of a machine is facilitated.

Description

technical field [0001] The invention relates to a control device and a control method of an electric tool, in particular to a start-up control device and a control method of a DC lawnmower. Background technique [0002] Lawn mowers are widely used as a lawn maintenance equipment, and can be divided into DC lawn mowers, AC lawn mowers and gasoline engine lawn mowers according to their power sources. Since the lawn mower has cutting blades, improper use may cause injury to the user or others, so the starting device and starting method of the lawn mower need to take personal safety factors into consideration. DC lawn mower refers to relying on direct current to drive the motor to make the lawn mower run. Usually, the DC lawn mower has a battery pack. The battery and the motor are connected through a circuit circuit. The battery provides power to the motor to drive the cutting of the lawn mower. blade. The starting device commonly used in the prior art includes an electric key...
